What about the growing bugs on the orchid? six treatment methods.

What about the bugs growing on the orchids? 1. Kill the insects with spirits

Liquor has a certain alcohol content, which can make the cells of pests lose water, so as to achieve the effect of killing pests.

Method

After mixing liquor and water at the ratio of 1 ∶ 5, the pest could be killed by applying it to the parts of Cymbidium damaged by shell insects and aphids, once a week for 3 to 4 times.

2. Kill insects with vinegar

Vinegar is also a very effective insecticide, it can effectively remove the pests on the orchid, suitable for killing those soft pests without shells, this method is convenient and safe, it can not only achieve the purpose of killing insects, but also make the damaged leaves green again.

Method

Can use vinegar 50 ml, put small cotton balls into vinegar soaked, with wet cotton balls on the damaged flowers and trees stems, leaves gently wipe, can wipe off the shell insects.

3. Use plant ash to kill insects

The residue of plants (herbs and woody plants) after burning is called plant ash. It belongs to an insoluble substance. Sprinkling plant ash on the orchid can block the aphids' breathing holes and suffocate them to death.

Method

A, sift the plant ash at the end of the grind, spray the plant ash on the aphids when the dew is not dry (or sprinkle water first) in the early morning, or shake it with gauze and sprinkle it again every three or five days for 2 to 3 times.

B, with 500 grams of plant ash with 2.5 kg of water, soak for one day and night to filter out impurities, and spray the injured orchid with filtrate, which can effectively kill aphids.

4. Kill insects with onions

Onions contain a special pungent smell that keeps pests away from orchids, especially for molluscs.

Method

Take 20 grams of onion, mash into a fine mud, add 1000 ml of water to soak for 24 hours and then filter and spray to prevent red spiders and aphids.

5. Killing insects with tobacco

Tobacco contains nicotine, that is, nicotine, which is highly toxic and long-lasting to insects. The solution made from tobacco can also invade the insect from any part of the body to poison the nerves and cause its death.

Method

We can use the cigarette butts left over from ordinary smoking and then mix the right amount of water to make insecticides, which can be sprayed on the leaf stems of Cymbidium, which has a good effect on aphids, shell insects, white flies, leafhoppers, bean flies and flat beetles.

6. Kill insects with soapy water

Soap contains fatty acid decomposing ingredients, which can be turned into a natural wax coating, which is sprayed on pests and causes them to dehydrate and die.

Method

Cut the remaining soap into thin slices, melt it with hot water, add water at the rate of 1:60, cool and spray on the orchid with a frequency of three times a week to prevent aphids and red spiders. If soap + tobacco + water can have the right insecticidal effect.

The orchid can absorb formaldehyde and create a good breathing environment for us. Leaves thin and light green, flowers small do not fly red, although do not understand those poetic flowers, but still can raise hanging orchid drop! The following Huahua will popularize the maintenance of hanging orchids for everyone!

I. the culture method of Cymbidium

Cymbidium is a perennial evergreen perennial herbaceous flower with various forms, strong shade tolerance and easy management. It is often used to hang potted plants for indoor decoration or garden setting. The following points should be mastered in its management:

1 light

Hanging orchids like a semi-overcast environment. Spring and autumn should avoid the strong direct sun, the summer sun is particularly strong, can only see some oblique light sooner or later, during the day need to cover 50% of the sun 70%, otherwise it will make the leaf tip dry, especially the flower and leaf varieties, more afraid of strong sunlight. But it should be more sunny in winter in order to keep the leaves tender and fresh green.

The family potted orchid should be placed in front of the south window, otherwise the leaves will lose their luster and even wither.

2 temperature

The optimum growth temperature of the orchid is 15 mi 25 degrees Celsius. If the winter temperature is lower than 5 mi 7 degrees Celsius, we should pay attention to cold protection and heat preservation.

3 watering

Hanging orchids like the humid environment, always keep the basin soil moist, adequate watering in summer, and spray water on the branches and leaves around noon and in the evening to prevent the leaves from drying up.

There is often much dust in the room, such as more dust on the hanging orchid, which not only affects the growth, but also harms the freshness and freshness of the branches and leaves, so we should often spray and wash the branches and leaves to keep them bright and beautiful.

Lower withered leaves, yellow leaves should be picked at any time, usually to maintain normal humidity, should not be dry, should not be too wet.

4 fertilization

Cymbidium is a more fertilizer-tolerant foliage plant, if the lack of fertilizer and water, it is easy to scorch head aging, leaves yellowing, loss of ornamental value. From late spring to early autumn, organic fertilizer can be applied every 10 days, but less nitrogen fertilizer should be applied to Phnom Penh, Jinxin and other mosaic varieties, so as not to fade or even disappear.

The retting organic manure such as bone meal and eggshell can be properly applied. After full fermentation, appropriate amount of diluent should be taken and poured once every 10 li for 15 days to make the flowers and leaves bright and bright.

5. Change soil and basin.

In the management of basin hanging orchid, in order to achieve luxuriant stems and leaves, the soil and basin should be changed once in March every year. If the basin is deeper and the base fertilizer is more sufficient, the basin can be changed once every two years. When turning the basin, knock the plant out of the basin, cut off the withered roots and excess roots, replace it with a new humus-rich culture soil, and then apply livestock hoof horns or rotten cake fertilizer as base fertilizer. After planting, put the seedlings in a warm and semi-overcast place.

The optimum growth temperature of Cymbidium is about 25 ℃. After the plant returns to robust growth, hang the flowerpot under the eaves of the corridor or in an appropriate position in the room. The general height is not to meet, and should pay attention to ventilation.

2. the method of hydroponic culture of Cymbidium

1 Select Container

Concise version: choose glass vases according to the size of hanging orchids, any yogurt bottle, beverage bottle or wine bottle, but the mouth of the bottle is a little smaller, so that the plant can be fixed and not tilted.

Tuhao version: Tuhao has its own hydroponic containers, all kinds of literary ceramic pots, online, florist everything, as long as there are coins in the pocket, what kind of hydroponic containers can be found!

2 take off the basin

Choose an auspicious day of the zodiac and remove the basin for the orchid. As long as the temperature is right and cooler, it will be fine.

Pull out the whole plant from the original flowerpot, and the strength must be small at this time. If you pull it out at once, it will be easy to break roots and leaves, and be gentle. Shake off the old soil above the root system and rinse it with water.

3 pruning

You don't need to be soft at this time, you must cut it again. Cut off all the ones with roots, leaving behind the stout roots that have not yet been planted.

Why do Huahua say so? hydroponic flower friends must know that those white and fat roots will rot after hydroponic culture and pollute the water quality, and they also need to be pruned in the later stage, so it is better to deal with them directly at the initial stage of hydroponic culture. After the root system is trimmed, the rotten leaves and weak leaves should also be cut.

In a word: cut off everything that should be cut, leaving a clean hanging orchid.

4 colonization

Put the trimmed hanging orchid into the container, this step many flower friends say it is difficult to operate, the hanging orchid always can not stand, stagnant.

If you buy a tuhao version of the container, you don't have to worry about it. But if you make your own hydroponic bottle, the flower will give you two tricks to make it easy to use.

According to the plant size, use a small mouth bottleneck to jam the orchid.

If you stubbornly want to use a jar, then you can.

In such a small space, even the smallest hanging orchid can stand.

5 add water

Some people like to add water before planting, but Huahua still recommends that you first plant and then add water. There is a scientific basis here.

Because it is best not to let the roots of the orchid all soaked in water, the water does not pass the root of the 1Accord 3-1 stroke 2 on it, leaving a few centimeters in the air can enhance the respiration of the roots.

As for how much this amount is, of course, after planting, it will be decided according to the length of the bottle and the root system, so water should be added later.

Third, the method of ramet breeding of Cymbidium.

Preparation tools: scissors, soil, flowerpots, orchids, water, sand

1 ramet soil culture method

① uses a shovel to break up the prepared flower soil, prepare scissors, flowerpots, and the right amount of water.

② found a vigorous new branch and cut it off with scissors. It is best to keep the rhizome so that it is easier to survive.

③ in the flowerpot to add half a pot of soil, add some water, if the soil is fine, it is recommended to spread a layer of granular soil at the bottom of the flowerpot, can better drainage.

After adding half the soil to the ④ flowerpot, hold the orchid by hand and put it into the pot. Add the soil until it is close to the pot surface. Add some more water. Remember to water regularly!

⑤ Ok, it's done! After transplanting, remember to wipe the soil around the flowerpot and take a beautiful picture.

2 ramet water culture method

① Cymbidium stolon grows a lot of small Cymbidium, when the small Cymbidium grows a little, about 5cm or so can be longer, take a basin, pour water, put the stolon into the water or the surface of the water, the ability to sense water is super.

② a few days later, look at the bottom of the orchid, there will be small white buds, this is the air root of the orchid, that is, in the case of sufficient water, the small orchid on the stolon will take root by itself.

③ will cut off the branch when the air root is longer. Find a glass bottle of about the same size, a basin of perfect hanging orchid is finished, it is so simple, it is so capricious!

Fourth, what about the dry tip of the leaves of Cymbidium?

1 failed to change the basin in time

If the basin is not changed for a long time, the nutrients in the soil will be exhausted, which is bound to affect the growth of the plant.

Solution:

The pot can be changed every March. If the plant is larger and the flowerpot is deeper, the pot can be changed every two years. When changing the pot, take the plant out of the flowerpot, cut off the withered roots, and apply a certain amount of base fertilizer to the soil. After changing the pot, put the plant in a warm semi-shady place to slow down the seedlings.

2 improper illumination

Cymbidium likes the environment with sufficient light, the lack of light affects the accumulation of photosynthetic nutrients, and the leaves are easy to dry up. But for the flower and leaf varieties of Cymbidium, yellow leaves will appear when the sun is too strong.

Solution:

In spring and autumn, avoid the strong sun at noon. In summer, the sun is particularly strong, with more than 70% shading during the day, except for some sunshine in the morning and evening. You can see more sunshine in winter to keep the leaves green. For the already yellowed leaves cut off in time, after replenishing the sun, new branches and leaves will grow slowly.

(3) improper fertilization

Cymbidium is a more fertilizer-tolerant plant, which is prone to plant senescence and leaf tip dryness due to insufficient fertilization.

Solution:

The application of organic fertilizer about 10 days from late spring to early autumn can appropriately reduce the content of nitrogen fertilizer for the varieties of flowers and leaves, so as to prevent the color of flowers and leaves from becoming lighter and affecting the ornamental.

4 improper watering

In the process of growth, the water is insufficient and the air is dry, especially when the orchid is placed in a narrow corner, the leaves will appear dry tip phenomenon because of the lack of water.

Solution:

Spring, summer and autumn, often spray water to prevent the leaves from drying up and moisturize the soil in the moisturizing basin. In addition, indoor culture, a lot of dust on the leaves, to regularly clean the leaves to keep the leaves gorgeous and beautiful.

Fifth, what if the leaves of hanging orchids turn yellow?

1 hypertrophy and burning seedlings

Fertilize too much, the orchid can not absorb the fertilizer, the rest of the fertilizer will burn out the roots of the orchid, reflected in the rest of the orchid, that is, the leaves turn yellow.

Solution:

Stop fertilizing immediately, irrigate clean water, or turn over the basin to change soil.

In addition, the usual fertilization should also pay attention to the usual demand for flower fertilizer is not very large, if you want the exuberant growth of Cymbidium, you can use bean dregs to soak in water, fully fermented and diluted. Can also use a little compound fertilizer, preferably organic fertilizer, nitrogen, phosphorus and potassium compound fertilizer is the best, once every half a month. When the temperature is below 4 degrees Celsius, the orchid should stop fertilizing.

2 improper illumination

If the orchid does not bask in the sun, the chlorophyll in the leaves will be reduced and the leaves will turn yellow. But exposure to the sun is also a kind of torture to the orchid, if the sun is too strong, the orchid will be "dried" oh ~ the leaves will turn yellow!

Solution:

We need to let the orchid be exposed to astigmatism for at least four hours a day, or we can put the orchid under the indoor incandescent lamp or on the balcony. When the sun is very strong in summer, put the orchid in the shade and do not expose yourself to the sun.

(3) improper watering

Too much watering, coupled with the basin soil drainage caused by stagnant water, the root system of the orchid can not breathe, reflected on the leaves is the leaves yellow! Another reason is that the hanging orchid is watertight for a long time, resulting in the loss of water at the root of the hanging orchid, and the lower old leaves will turn yellow.

Solution:

Water too much to timely loosen the soil and control moisture, and usually watering must be thoroughly. In general, the orchid is watered once every ten days in winter and every five days depending on the dry condition in summer. It should be thoroughly watered and drained smoothly.

If the air is dry, you can often spray and wash the branches and leaves with a sprayer, which can not only increase the air humidity, but also prevent the dry tip of the leaves, but also keep the leaves clean, improve the ornamental, and get more with one stone.

In addition, watering time flower friends should pay attention to, it is best to water in the morning or evening, can not be watered at noon, a hot day suddenly to the hanging orchid basin cold water, will be thoroughly cold.

4 temperature discomfort

The suitable temperature for the growth of Cymbidium is 15-25 ℃, the fastest growth is when the temperature is 20-24 ℃, the growth stops above 30 ℃, and the overwintering temperature is 5 ℃. If the temperature is too low or too high, the leaves will turn yellow!

Solution:

The best solution, of course, is to give the orchid a suitable temperature ~ the most suitable growth temperature is 20-24 ℃. Usually I think it's good to keep this temperature.

(5) insufficient nutrition

The source of nutrition here is not only fertilizer, but also the soil itself. If the basin soil is not replaced for a long time, the lack of some trace elements will lead to poor growth and yellowing of leaves.

Solution:

Of course, the best way to solve this problem is to change the basin for the orchid. Remember to mix fertilizer when changing the basin to avoid the loss of fertilizer and burning roots.

6. What about the rotten roots of hanging orchids?

1 the water is big

Reason:

Hanging orchid, like water, but also the most taboo water, too much watering, the root for a long time soaked in anoxic environment, over time, the root system will blacken and rot.

Solution:

Reduce watering, bask in the sun more, strengthen ventilation, and let the moisture in the soil evaporate as soon as possible. Several holes can be made around the root of the orchid to increase air permeability. If there is too much watering, it is recommended to remove the basin directly, dry the soil or change the new soil.

If it is found that it is not timely and the rotting roots of Cymbidium are serious, it is recommended to remove the plant from the pot, trim the rotten roots, soak them in disinfectant for a while, dry them for 2 or 3 days, and then plant them with new soil.

2 fat weight

Reason:

Whether fertilizing too much orchid itself will have a sense, frequent fertilization or fertilization is too thick, it is easy to burn roots.

Solution:

If the concentration of fertilizer is too high, water should be watered immediately to let water flow out from the bottom of the basin. Or, remove the plant from the pot and change the soil. In addition, timely check the root rot, trim the root, disinfect the slow root.

(3) soil clay

Reason:

If the soil is not changed for a long time, there will be the problem of soil consolidation, and the soil viscosity is heavy, which is not conducive to the growth of roots.

Solution:

This is the simplest and most direct way to change soil. For soil hardening is not very serious, you can mix perlite into the soil to ease it. The more serious consolidation can be replaced with loose and fertile soil.

4 injuring root

Reason:

The root injury may be an instant thing, when you change the basin, one will appear carelessly, scratch the skin, break the root, and there will be no problem in a short time. But in the soil environment, the roots with wounds will slowly rot.

Solution:

Try to avoid damage to the root system, in the process of basin change, root trimming, we should pay attention to handle it gently.

Within 1 ~ 2 months after root injury, the root system will gradually rot if it can not be recovered. After changing the basin, we should pay attention to check the growth of Cymbidium, and deal with any abnormality in time. If the root is completely rotten, the hope of regeneration is a little slim, but a timely transplant can be saved. Cut off the small plant on the stem of the plant, plant it directly in the culture soil or water, and wait for it to take root.

5 Diseases and insect pests

Reason:

Diseases and insect pests are an unavoidable problem for many plants. When bacteria, fungi and even root-knot nematodes are found in the soil, the root is of course the first to bear the brunt. Worms eat the roots and then cause decay.

Solution:

If the rotten root is light, the pot soil can be irrigated with 400-500 times carbendazim solution for sterilization and disinfection. Use it once a week for three weeks to remove the yellow leaves.

If the rotten root is serious, dig it out, cut it off, disinfect it with potassium permanganate solution, and dry it in a ventilated place, about 1 day or 2 days, and replant it.

6 the temperature is low

Reason:

The root of the orchid is very sensitive, especially the hydroponics, environment and water temperature are very important. When the water temperature is quite different from the room temperature, or the newly added water is too cold, the growth of the roots will be affected, which may cause rotten roots.

Solution:

Hydroponic hanging orchid rotten root is much easier, often check the growth of the root system, rotten root system should be cut off in time. Pay attention to changing water at ordinary times, make sure it is equal to room temperature, and avoid overcooling or overheating.

7. Excess nutrition.

Reason:

Many people love nutrient solution when maintaining hydroponic plants. If it is used too much, it will affect the growth of Cymbidium. The content of dissolved oxygen in the nutrient solution of hydroponic culture is low, resulting in the death of plant roots due to hypoxia and gradual decay.

Solution:

Change the water frequently, clear the container wall and the root system of Cymbidium every time. The nutrient solution can be used, but be careful not to overdo it. Follow the instructions.

After the roots of Cymbidium are rotten, you can only raise them with clean water. Wait for the roots to adapt to the environment, and then add nutrient solution after growing new roots.

8 the water quality is poor and the water level is high

Reason:

This problem of water quality should be well talked about. If there are residual plant debris or residual matrix or nutrient solution precipitation in the water, it is easy to cause rotten roots. In addition, the level of water level is also the key factor of rotten roots.

Solution:

Leave half of the orchid root in the nutrient solution, while the other half is exposed to the air. This can greatly increase the oxygen supply of plant roots and effectively reduce the occurrence of root rot.

Change the water in time to ensure that the water quality is clean. The tap water at home should be used after one day.

1 display of hanging orchids in the kitchen

The kitchen generally uses white or light color decoration, stainless steel sink, hanging orchid can soften hard lines, so that your kitchen is full of vitality. Put the orchid by the window or on the table away from the stove, and the air in the kitchen will be great.

2 bedroom with hanging orchids

Hanging orchid easy to maintain, put at the head of the bed or bedside, the sun came in, simple and elegant bedroom, plus green hanging orchid, in a good mood. Choose the hanging orchid is not the whole plant, choose a small plant or hang on the wall opposite the bed.

3 hanging orchids are placed in the living room

General door to the west of the living room is relatively bright, the application of gold and soil potted plants, hanging orchids can be. Put on the coffee table in the living room or next to the TV cabinet, full of positive energy, but also can effectively absorb harmful gases in the air.

All right, all the frequently asked questions are introduced.

Florists, do you have any questions?

Comment on it below.

Huahua is waiting for you!

Your orchid will never die again because of its maintenance knowledge.

Your orchid will never die again because of its maintenance knowledge.

Are you still struggling with the hanging orchids at home? Still watching his own dead hanging orchid crying without tears? Today Huahua gives you a copy of the all-round maintenance of hanging orchids, from maintenance to frequently asked questions, are you sure you don't want one?

Daily maintenance

Lighting requirements:

Hanging orchids should be placed in bright living rooms and other places. When cultivating, we should pay attention to the need for shade if the light is too strong. Temperature requirements: Cymbidium likes warm and humid climate, is afraid of cold and high temperature, grows fastest at about 20-24 ℃, stops growing above 30 ℃ and below 0 ℃, and leaves are easy to turn yellow and dry. Moisture requirements: in the peak growing season, watering should be adequate, basin soil should always be moist, and branches and leaves should be sprayed with water close to room temperature to prevent dry tip, but not stagnant water. Soil requirements: if the basin has not been turned over for a long time. The various nutrient elements in the basin soil have been exhausted, the three elements of nitrogen, phosphorus and potassium have not been replenished in time, the plant is lack of nutrients, and the leaves are yellow and thin. Fertile loam, compound fertilizer and slow-release fertilizer should be replaced in time. As the plant grows, it is necessary to trim and change the pot. in order to maintain a good plant shape, the old leaves at the base should be cut frequently and the soil should be changed every once in a while. Fertilization requirements: apply more nitrogen fertilizer, but not too much at one time, it is best to apply thin fertilizer frequently. If you fertilize too much, more than the plant needs, at the beginning, the leaves are bright and uneven, and then the roots rot, and the leaves will be yellow. you should stop fertilizing, irrigate more water, or turn the pot to clean the roots and replace the new soil.

Winter maintenance tips

YANGHUADAQUAN

Under 5 ℃ in winter, less watering, basin soil should not be too wet, otherwise the leaves will be easy to yellowing. Stop fertilizing when the ambient temperature is below 4 ℃.

North China

In areas with heating in the north, normal indoor maintenance is fine. Please join us for details.

If there is no heating in the north, try to ensure the temperature, do not water, because the orchid is fleshy root, will store some water, do not water temporarily will not die, even if the leaves withered, there is still a chance to sprout next spring.

South

There is no heating in some parts of the south, but the temperature is relatively cold in winter. As long as there is no ice, the orchids can survive. Do not worry about the withered leaves, flower friends, and remember not to water them, so that the roots are still alive. Spring can bring life back to life.

Hydroponic orchid

YANGHUADAQUAN

Tools, raw materials:

1. Hanging orchids, small scissors 2, bottles, trays or decorative pots 3, cold boiled water or treated tap water

Step 1: choose tap water after placement

Find a transparent glass bottle filled with water. Remember: it can't be ordinary tap water. Because tap water contains chemicals such as bleach, it is not conducive to the growth and development of the root system of Cymbidium. Preferably cold boiled water, no diseases and insect pests, algae spores and other acrobatics.

The tap water released from the faucet should be left open for 12 hours to remove chlorine from the tap water, which is more conducive to the healthy growth of plants, especially the roots can keep white and tender for a long time without turning green and improve ornamental.

Step 2: place washed pebbles

Wash the pebbles. Many novices try to grow water-raised orchids for the first time, simply thinking that as long as they put them in the water.

In fact, if the whole plant is immersed in water, the root of the orchid will rot due to excessive anaerobic respiration. Find some pebbles of the right size and smooth appearance, wash them and put them into a glass bottle, accounting for about 2/5 of the total volume of the bottle.

Step 3: choose the plant on the stem.

To select varieties, we can choose the aerial root of the plant on the stem to plant, because this kind of aerial root is very suitable for hydroponic environment, it is relatively easy to manage, and the root system will sprout after 5 days of water culture.

Cut off the orchid with small scissors, remove the old leaves, cut off the old roots, leave only a few new leaves, and slowly put them into the bottle. Too many old leaves and roots will not only consume nutrients in vain, but also delay the germination of new roots, so they must be removed.

Step 4: take root after 3-5 days

After about 3 to 5 days, something a little white begins to appear on the top or edge of the original green root (air root). If you take a closer look, you may cry out with surprise: "A new root has grown!" With the passage of time, there are more and more new white roots and gradually fill the bottle.

Before and just growing roots, do not change water frequently, because young roots just grow out of particularly fragile, the process of changing water will hurt young roots and hinder the growth rate of young roots.

Step 5: change water frequently in post-management.

In the post-management process, the most important thing is to change water frequently. Especially in the high temperature season, the respiration of plants is strengthened, and in addition, in its own metabolism, it can also convert the carcinogenic formaldehyde in the air into sugars and amino acids, which can be transported to the roots or released in water.

If you can not change the water in time, the clear water quality will turn gray, and a layer of dirt will float on the surface, which will seriously lead to rotten roots, slippery and dirty with your hands.

Step 6: clean up the aging excess roots regularly

When there are more and more new roots, you must also pay attention to two points: first, you can use small scissors to cut off some of the earlier roots in time; second, do not let the whole root be immersed in water. The roots need to be exposed in the air for a few centimeters, so that even if the roots soaked in the water cannot absorb oxygen, the roots exposed in the air can replenish some oxygen.

Step 7: add a small amount of nutrient solution on time

Hanging orchid does not like direct light, generally placed in a place where there can be scattered light, on the line. The requirement for water nutrition is not high. After half a month or so, less nitrogen fertilizer or granular compound fertilizer can be added to the water, and the proportion of fertilizer and water will be 11500.

People also have the habit of growing flowers with rice water. However, the Amoy rice water must be placed for three or five days, and after full fermentation, the supernatant is taken. However, the concentration is not too high when mixed into the water-raised hanging orchid bottle at the ratio of 1:10.

common problem

YANGHUADAQUAN

1 dry tip of hanging orchid

1. Give the root system a comfortable home

Selecting a flowerpot and suitable culture soil suitable for the root growth of Cymbidium is the basis of cultivating Cymbidium. If you want to develop a potted plant of a certain scale, you should choose a barrel-shaped basin with a diameter of more than 20 centimeters, so that the root system can stretch.

Before planting, the basin bottom should be covered with 3 cm sawdust or small gravel as drainage layer, and loose and breathable sandy loam and rotten leaf soil should be added to make the root system not only absorb water and fertilizer, but also breathe freely, so that it can grow healthily. Generally speaking, small cuttings are used in small pots, and large pots are replaced after full growth.

Let the basin soil be a little dry, will you

Many people believe that hanging orchids like a warm and humid environment, so they should keep the basin soil and the environment moist and spray water 1-2 times a day in order to keep the leaves green and not dry. In fact, in family maintenance and management, spraying water every day is very troublesome, and it will also have an impact on the surrounding environment, such as furniture, walls and so on.

In fact, hanging orchid in the long-term family maintenance, has adapted to the dry environment. As long as the root system grows normally, it will not dry tip. Therefore, on weekdays, watering should be done without drying or watering, and watering should be thoroughly watered. Sometimes even if it is dry, the leaves become weak and recover quickly after watering. On the contrary, if the potted soil is too wet, it is easy to rot the roots and form dry tips and yellow leaves.

3. Topdressing too much, not good ~ bad ~

Hanging orchids do not like thick fertilizer, and many dry tips of hanging orchids occur after fertilization. Some people like to add liquid fertilizer or chemical fertilizer when watering, resulting in too high concentration of mineral elements in the basin soil.

Raising Cymbidium can basically not be fertilized. When the pot is changed in spring, the loose and fertile soil can be used as the foundation to make the branches flourish, and then the mature fertilizer can be irrigated 1-2 times during the bud formation period.

4. Ventilation is good for people and plants.

The hanging orchid is indeed a green plant that can absorb a variety of harmful gases and is very suitable for the maintenance of new houses. However, the amount of some toxic gases absorbed by Cymbidium is limited, and drug abuse by Cymbidium or other green plants alone can not solve the fundamental problem of indoor pollution.

In fact, the orchid itself also needs fresh air and ventilation. A poorly ventilated environment is also easy to dry, so check to see if the doors and windows are closed all the year round.

5. Return the orchid to a stable environment

Hanging orchids do not like strong light, domestic hanging orchids should avoid direct sunlight, but too dark will also affect growth. If the pot hanging orchid is placed improperly, the light is too strong or too dark, even if there is enough fat and water, it can not be raised well.

You should choose a place with bright scattered light, and it doesn't hurt to see some sunshine every day in spring, autumn and winter. For example, the inside of the south balcony, 1 meter in front of the south window can be placed for a long time, generally do not need to move back and forth.

2 yellow leaves of Cymbidium chinense

The most common reason: overwatering

Hanging orchid afraid of stagnant water, watering too much plus basin soil drainage is not smooth, the root of the hanging orchid can not breathe, it will lead to yellow leaves.

Solution:

In this case, if you water too much water, you should loosen the soil in time and let the excess water evaporate as much as possible, and then you must not water more in the daily watering. Basically, it is good to master the principle of "dry and wet". The orchid is watered once every ten days in winter and every five days depending on the dry condition in summer. It should be thoroughly watered and drained smoothly.

Other reasons:

1. Lack of light

Although the orchid can grow in the shade, it does not mean that the orchid does not need sunlight. If the orchid is placed in the shady corner for a long time, the chlorophyll in the leaves will decrease and it will slowly turn yellow. If you always expose the orchid to the sun, it will also cause the leaves to turn yellow.

Solution method

It is best to let the orchid receive at least 4 hours of light every day, or you can put the orchid under the indoor incandescent lamp or on the balcony. When the sun is very strong in summer, put the orchid in the shade and do not expose yourself to the sun. In winter, you can put the orchid on the south balcony and other places to bask in the sun.

two。 Excessive nutrition or too little nutrition

There is too much fertilizer for the orchid to digest, and the remaining fertilizer will burn the roots of the orchid. Immediately stop fertilizing, irrigate the water, or turn the basin to change the soil. And less fertilizer, nutrition can not keep up, but it will turn yellow? The basin soil should be changed in time.

Solution method

In addition, hanging orchid usually does not have a great demand for flower fertilizer, so it can be soaked in water with bean dregs and diluted after full fermentation. Can also use a little compound fertilizer, preferably organic fertilizer, nitrogen, phosphorus and potassium compound fertilizer is the best, once every half a month. When the temperature is below 4 degrees Celsius, the orchid should stop fertilizing.

3 soil culture to hang orchid rotten root

Reason 1: the water is too large

Hanging orchid, like water, but also the most taboo water, too much watering, the root for a long time soaked in anoxic environment, over time, the root system will blacken and rot.

Solution:

Reduce watering, bask in the sun more, strengthen ventilation, and let the moisture in the soil evaporate as soon as possible. Several holes can be made around the root of the orchid to increase air permeability. If there is too much watering, it is recommended to remove the basin directly, dry the soil or change the new soil.

If it is found that it is not timely and the rotting roots of Cymbidium are serious, it is recommended to remove the plant from the pot, trim the rotten roots, soak them in disinfectant for a while, dry them for 2 or 3 days, and then plant them with new soil.

Reason 1: fat

Whether fertilizing too much orchid itself will have a sense, frequent fertilization or fertilization is too thick, it is easy to burn roots.

Solution:

If the concentration of fertilizer is too high, water should be watered immediately to let water flow out from the bottom of the basin. Or, remove the plant from the pot and change the soil. In addition, timely check the root rot, trim the root, disinfect the slow root.

Reason 3: soil stickiness

If the soil is not changed for a long time, there will be the problem of soil consolidation, and the soil viscosity is heavy, which is not conducive to the growth of roots.

Solution:

This is the simplest and most direct way to change soil. For soil hardening is not very serious, you can mix perlite into the soil to ease it. The more serious consolidation can be replaced with loose and fertile soil.

Reason 4: root injury

The root injury may be an instant thing, when you change the basin, one will appear carelessly, scratch the skin, break the root, and there will be no problem in a short time. But in the soil environment, the roots with wounds will slowly rot.

Solution:

Try to avoid damage to the root system, in the process of basin change, root trimming, we should pay attention to handle it gently.

Within 1 ~ 2 months after root injury, the root system will gradually rot if it can not be recovered. After changing the basin, we should pay attention to check the growth of Cymbidium, and deal with any abnormality in time. If the root is completely rotten, the hope of regeneration is a little slim, but a timely transplant can be saved. Cut off the small plant on the stem of the plant, plant it directly in the culture soil or water, and wait for it to take root.

Reason 5: diseases and insect pests

Diseases and insect pests are an unavoidable problem for many plants. When bacteria, fungi and even root-knot nematodes are found in the soil, the root is of course the first to bear the brunt. Worms eat the roots and then cause decay.

Solution:

If the rotten root is light, the pot soil can be irrigated with 400-500 times carbendazim solution for sterilization and disinfection. Use it once a week for three weeks to remove the yellow leaves.

If the rotten root is serious, dig it out, cut it off, disinfect it with potassium permanganate solution, and dry it in a ventilated place, about 1 day or 2 days, and replant it.

4 hydroponic rotten root

Reason 1: low temperature

The root of the orchid is very sensitive, especially the hydroponics, environment and water temperature are very important. When the water temperature is quite different from the room temperature, or the newly added water is too cold, the growth of the roots will be affected, which may cause rotten roots.

Solution:

Hydroponic hanging orchid rotten root is much easier, often check the growth of the root system, rotten root system should be cut off in time. Pay attention to changing water at ordinary times, make sure it is equal to room temperature, and avoid overcooling or overheating.

Reason 2: overnutrition

Many people love nutrient solution when maintaining hydroponic plants. If it is used too much, it will affect the growth of Cymbidium. The content of dissolved oxygen in the nutrient solution of hydroponic culture is low, resulting in the death of plant roots due to hypoxia and gradual decay.

Solution:

Change the water frequently, clear the container wall and the root system of Cymbidium every time. The nutrient solution can be used, but be careful not to overdo it. Follow the instructions. After the roots of Cymbidium are rotten, you can only raise them with clean water. Wait for the roots to adapt to the environment, and then add nutrient solution after growing new roots.

Reason 3: poor water quality and high water level

This problem of water quality should be well talked about. If there are residual plant debris or residual matrix or nutrient solution precipitation in the water, it is easy to cause rotten roots. In addition, the level of water level is also the key factor of rotten roots.

Solution:

Leave half of the orchid root in the nutrient solution, while the other half is exposed to the air. This can greatly increase the oxygen supply of plant roots and effectively reduce the occurrence of root rot. Change the water in time to ensure that the water quality is clean. The tap water at home should be used after one day.
