Flower cultivation: 3 tricks to help you solve the problem of yellowing of leaves!

Plant leaves yellowing, both affect the beauty, serious may lead to plant death, but also a headache for growers, welfare has arrived, today Huinong network editor will teach you three ways to bid farewell to plant leaf yellowing trouble!

3 tips for solving the yellowing of leaves:

Green pineapple

1. Soybean water

Green pineapple leaves turn yellow because of lack of nutrition, which can be treated with soybean water. It is rich in nutrient elements and weakly acidic, which can adjust the acidity of soil.

Usage: (1) boil the soybeans in clean water. The pots that boil the soybeans should be clean and oil-free, and salt should not be added to the water. (2) after cooking, remove the soybeans, cool the soy water and pour it on the green apple.

2. Aspirin

Green pineapple watering too much is easy to yellow leaves, mainly because there is too much water in the soil, bacteria breed, affecting the life activities of green pineapple. Aspirin contains salicylic acid, which can be sterilized, enhance plant cell activity, and relieve green radish yellow leaves.

Usage: 1. Break two aspirin tablets with a rolling pin and mix them in 500g water. 2. Pour the aspirin solution to the green apple.

3. Maintenance

Green pineapple should be placed in an indoor ventilated and bright place, preferably near the windowsill of the living room or study, pay attention to watering frequency, flowers are generally watered once every 4-6 days, flower friends should be watered according to the actual situation.

Hanging orchid

1. Broken bones

Leftover fish bones, chicken bones, pig bones and so on, a simple treatment, can supplement nutrition for the orchid, to avoid the lack of nutrition and yellow leaves.

Usage: (1) boil the leftover bones in the pot for half an hour and boil off the salt in the bones. (2) smash the bones and dry them, then dig a small hole in the edge of the basin soil of the orchid and put a small amount of broken bones in it.

2. Fish tank water

The water replaced in the fish tank can water the flowers. on the one hand, the water has a high oxygen content and can avoid rotten roots and yellow leaves to a certain extent; second, the water contains fish excretion, which can supplement the nutrition for the orchid.

Usage: replace the fish tank water and pour it directly to the hanging orchid.

3. Maintenance

Hanging orchids need to be sprayed around to avoid dry tips, and to avoid putting them in such shady places as toilets. Flowers generally water their own hanging orchids every 5-7 days.

Make a fortune tree

1. Less watering

99% of the rich trees died from watering, and most of the rich trees had yellow leaves because of overwatering. The root system of the rich tree is very underdeveloped. once it is overwatered, it is difficult to breathe, and then the yellow leaves rot the roots.

Xiaobian's rich trees are usually watered only once in more than half a month. Flower friends should determine their own watering frequency according to their own conservation status and take flowers as a reference. If they are flower friends in the south, if the temperature is relatively high, they can appropriately increase the watering frequency.

2. Compound fertilizer

Having fewer roots does not mean that there is no need for nutrition. on the contrary, rich trees with larger plant size need more nutrients to maintain their own supply, otherwise they will have yellow leaves. At this point, a few grains of compound fertilizer can make the rich tree avoid yellow leaves.

How to use it:

1. Dig a small hole at the edge of the rich tree basin soil and put 5-10 grains of compound fertilizer in it according to the size of the rich tree.

2. Watering after burying, observe for two days, if the rich tree has no obvious bad condition, you can add 2 fertilizers appropriately next time and use compound fertilizer once a month.

3. Large pots and deep pots should not be used to maintain small rich trees. Because the root system of the small rich tree is short, and there is too much soil in the big basin, after watering, the water in the upper soil is absorbed by the rich tree, although the soil below is still moist, the rich tree has no way to continue to absorb water, so it can only continue to water. In the long run, it is easy to rot the roots with yellow leaves.

Gentleman orchid

1. Beer

Beer is rich in carbon dioxide, which can promote the photosynthesis of Cymbidium, avoid the yellow leaves of Cymbidium, and make it green.

Usage: 1. Beer is diluted with water at the ratio of 1:10. 2. Dip the diluted beer with cloth and wipe the leaves of Cymbidium.

2. Bury melon seeds

Gentleman orchid especially likes oil crops, fry melon seeds, peanuts, castor seeds and so on into the flowerpot of gentleman orchid, can prevent it from yellowing because of lack of nutrition.

Usage: dig a small hole next to the magnolia basin soil, throw in more than a dozen melon seeds and peanuts, and bury them.

3. Maintenance

Gentleman orchid had better be placed in the study, living room and other places, do not accept direct sunlight, usually should be more scrubbing leaves.

Asparagus asparagus

1. Bean cake

Water bean cake is the residue left after oil extraction of soybeans, peanuts and sesame seeds. It is nutritious and can be fed to asparagus to avoid its yellow leaves due to lack of nutrition.

Usage: (1) break the bean cake and seal it with water and put it in the sun. (2) it can be used after about 2 months. When using, take the supernatant and pour it to asparagus with water according to 1VR 2000.

2. Spray

Asparagus originally lived in the south, the air humidity is high, after entering the room, because the humidity can not reach, often yellow leaves, so if you want to avoid yellow leaves of asparagus, you need to spray around asparagus to moisturize.

Usage: spray around asparagus every day.

3. Maintenance

Asparagus does not like direct sunlight, but it should not be overshadowed. It should be placed in an indoor ventilated and bright environment. Flowers should water their asparagus about once every 4-6 days.

Jasmine

1. Ferrous sulfate

Jasmine is a southern flower, originally grown in the red soil, the soil is rich in iron. After moving into the indoor flowerpot, if there is not enough iron, the leaves will be yellow, so it needs to be poured with ferrous sulfate.

Usage: dilute ferrous sulfate in the ratio of 1 to 2000 and pour it into jasmine.

2. Vinegar

The northern basin soil is partial to alkali, which is also the reason why many northern flower friends can not raise jasmine and gardenia well. You can use vinegar to neutralize the alkalinity in the basin soil.

Usage: White vinegar should be salt-free, diluted according to the proportion of 1:50, then pour down the jasmine.

3. Maintenance

It is said that jasmine blossoms more and more fragrant, the growth of jasmine needs plenty of sunshine, it is best to put it on the balcony with good light.

Happiness tree

1. Rice washing water

Amoy rice water is weakly acidic and contains nutrients, which can alleviate the yellow leaves of happiness trees due to lack of nutrients.

Usage: a small amount of rice washing water can be used directly. When using a large amount of rice washing water, you need to put it in a plastic bottle first and then use it after sealed fermentation.

2. Tea

The tea is weakly acidic, and overnight tea can be poured on the happiness tree, helping to relieve its yellow leaves.

Usage: filter out the tea in the tea and pour the tea to the happiness tree. Pay attention to this method to have a certain frequency, can be once every half a month, can not take the happiness tree as a tea bucket, otherwise it is easy to rot roots.

3. Maintenance

The happiness tree likes the semi-shady environment and is suitable for the broad and bright living room, which is watered every 5-7 days. Rich bamboo 1, iron nails rich bamboo yellow, mostly because of the lack of iron, rusty iron nails can release iron elements, ease the yellow leaves of rich bamboo.

Usage: (1) find the old rusty nails, do not remove the rust. (2) after changing the water, throw the nails into the water culture bottle.

2. Charcoal

Another important reason for the yellow leaves of rich bamboo is that the water quality is unclean. If the water in the hydroponic bottle is not changed all the year round, it will lead to rotten roots and yellow leaves. Charcoal can absorb impurities to purify water and prevent rich bamboo from rotting roots and yellow leaves.

Usage: (1) smash the charcoal into pieces the size of the belly, be careful not to be too small, otherwise the adsorption capacity will be much worse. (2) put 7-10 pieces of charcoal into a hydroponic bottle and change the charcoal with the water when changing water.

3. Maintenance

To put the rich bamboo in the living room, study and other bright places, change the water every 10 days or so, and cut off the yellow leaves in time.

The above are different types of plant leaf yellow problems sorted out by Huinong net Xiaobian, and the treatment methods. I hope it will be helpful to the growers!

Goldfish orchid blossoms several times a year. What if the leaves turn yellow?

Goldfish hanging orchid, also known as goldfish flower, gets its name because its flowers are similar to goldfish. Goldfish hanging orchid is one of the common family farmed flowers in our life, because it is easy to breed, and the flowers are unique in shape and colorful, so they are deeply loved by everyone. So when do goldfish orchids usually blossom?

Goldfish orchid blossoms several times a year

Theoretically, the flowering time of goldfish orchid is in winter, but the flowering time of goldfish orchid is a little out of order because of the different maintenance environment. It is possible that some areas blossom at the end of March, some in early May, and some in October and December.

What if the goldfish orchid leaves turn yellow?

1. Environment. Ensure that the growth environment of goldfish hanging orchid is in a semi-shady environment to avoid strong sunlight.

2. Moisture. Pay special attention to the watering of goldfish orchids, to ensure that the soil is moist, but do not let stagnant water in the basin, especially in summer, always spray water around the flowerpot or on the leaves to keep moist.

3. Temperature. Ensure that the growth temperature of goldfish orchid is about 20 degrees Celsius, and the indoor temperature in winter is about 5 degrees Celsius.

Culture method of goldfish Cymbidium

1. Soil: goldfish orchid potted plants require that the substrate is rich in humus, loose and well drained. Peat soil, perlite and vermiculite are commonly mixed, and the soil leaves are slightly acidic to facilitate growth.

2, temperature: the best growth temperature of goldfish hanging orchid is about 18-22 ℃, and it is not cold-resistant. If the lowest temperature is lower than 10 ℃, it will cause goldfish hanging orchid leaves to turn yellow, dry, and even defoliate, avoid high temperature, and even cause defoliation if the temperature exceeds 30 ℃.

3, lighting: goldfish hanging orchid likes negative environment, can not be exposed in the hot sun, before flowering in winter can appropriately increase sunlight exposure, will increase the quality of flowering. But the sun can not directly shine on the goldfish orchid, otherwise the leaves will wither or even die.

4. Humidity: the growth of goldfish hanging orchid needs sufficient moisture, always keep the basin soil moist in the peak growing season, and water again after drying at a depth of about one centimeter on the surface of the basin soil in winter. But not too much water, otherwise it is easy to rot the root.

5. Fertilization: thin organic fertilizer solution was applied every 1-2 weeks in the peak growing season. Phosphate fertilizer should be added before flowering to increase the quantity and quality of flowering, and nitrogen fertilizer should be applied after flowering. Nitrogen-based topdressing can be applied to those who have begun to grow small plants every half a month.

The function of goldfish orchid

1. Ornamental function

The appearance of goldfish hanging orchid is one of the reasons why it is very popular, because it has bright colors, hundreds of flowers can bloom on the same plant, and the flowers are large and beautiful, which can increase the beauty of the room when planted at home or in the courtyard. if you plant a large number of plants, it will look more spectacular.

2. Purify the air

Goldfish orchids, which are also green plants, are both beautiful and noble if they are potted indoors, and goldfish orchids can absorb indoor carbon dioxide and some toxic substances, such as some newly decorated houses can plant several pots of goldfish orchids, which can quickly help you purify the indoor air, in addition, goldfish orchids can also play a wetting effect indoors, and its purification effect is very powerful. So it is said that breeding several pots indoors can not only watch but also purify the air. Goldfish orchids can carry out photosynthesis in weak light and can absorb 80% of the harmful and toxic gases in the room. Generally, 1-2 pots in the room can absorb all the toxic gases, but it is a different matter if the room is very large. A basin in a room of 8-10 square meters is equivalent to an air purifier.

3. Family potted plants

Because the growth ability of goldfish hanging orchid is very strong, and its stem hangs naturally, it is very suitable for family potted plants, especially for some people who usually spend a lot of time to take care of it. In its full bloom, more than a hundred flowers can bloom on a plant at the same time, and the flowers are huge and colorful, which is really spectacular. It is a kind of plant that is satisfied with both negative and negative hanging leaves and ornamental flowers. Goldfish orchids can be raised indoors or in their own courtyards or gardens at a suitable temperature. This kind of flower is not very difficult to raise, and can also be used as a family hanging.

As mentioned above, the flowering time of goldfish orchids is different in different places, which is mainly determined according to the climate. Goldfish hanging orchid is very suitable as a potted plant, small and delicate, not only beautiful, but also can purify the air!

Are potted green roses and magnolia succulent plants afraid of heat? How do you spend the summer with flowers and plants at home?

Huangmei season is the season of a large number of plant diseases and insect pests. It is expected that there will be more dog days this year than last year. Garden experts teach you to avoid three misunderstandings and do a good job in three details.

Help your family's flowers and plants spend the summer safely.

Jiangsu, China, July 14-Changzhou has been ambushed, and the Meiyu day just ended yesterday, but the weather is still humid and muggy, and the ensuing dog days are even more powerful because of the help of El Nino. This summer, the life of plants at home is destined to be difficult. However, it does not matter. A few days ago, the reporter interviewed Changzhou garden experts and obtained some conservation secrets for everyone. As long as they do not offend the following misunderstandings of growing flowers in summer and do a good job in the relevant details, even in this humid, high-temperature, unpredictable weather, your flowers and plants will certainly be able to survive safely.

These three "take for granted" are all wrong.

It is rare for the sun to bask in the sun after rain.

Myth 1: having just come out of the plum and saw the sun that has not been seen for a long time, many citizens feel that they should move the plants out to enjoy the sunshine they have not seen for a long time.

Experts read: "do not directly get exposure to the sun." Xu Yi, a staff member of Changzhou Greening guidance Station, said that too strong environmental changes are not conducive to the growth of plants, especially the recent rainy Huangmei days encountered sudden high temperatures in dog days, and plants that have lived indoors for a long time are suddenly exposed to the sun, which can easily cause burns of tender leaves and buds. In addition, shading and ventilation should be done for negative plants. Potted flowers put outdoors can be moved to the ventilation place for shelter from the rain; if it is not easy to move, the bottom of the pot can be put up to remove the stagnant water plate and create drainage and ventilation conditions.

If it is rainy in summer, you need more fertilizer.

Misunderstanding 2: after the heavy rain in summer, the nutrients in the soil will be lost with Rain Water, so it is necessary to apply more fertilizer.

Experts interpret: "in summer, especially in Huangmei season, fertilization should not be too much, especially unfermented human feces and urine, chicken manure, milk, soybean milk, fish offal and chemical fertilizer." Xu Yi said that improper fertilization in Huangmei season is mainly reflected in two aspects: first, burning seedlings caused by excessive concentration, such as excessive urea will cause rapid withering and blackening of leaves and flowers; and second, humid air in summer and breeding of microorganisms. at this time, random fertilization is very likely to cause plant roots to rot because of too many microorganisms.

There is no need to water after such a long time of rain.

Myth 3: after continuous overcast and rain, the humidity is relatively large, and the soil is relatively easy to moisturize, so there is no need for watering.

Experts read: "even in the rainy summer, the right amount of watering is still essential." Especially the high temperature after rain should pay more attention to plant moisturizing. " Xu Yi said that some time ago, the overall humidity in the Meiyu season was on the high side, and even if the soil water content increased, timely watering was needed, and attention should be paid to controlling the frequency of root watering, with the exception of succulent plants. See that the basin soil is dry and then watered, the leaves of the plants need to be properly wiped to keep the plants breathing smoothly. Do not have stagnant water, strengthen ventilation after watering, let it dry naturally.

The more varieties of plants raised in Changzhou are orchids, green apples and succulent plants.

These plants with high appearance rate should be very careful in summer.

What is mentioned above is the method for most plants to spend the summer, but different plants have different temperaments and weaknesses. Gentleman orchids, green apples, and succulent plants are all more varieties raised in Changzhou families. Wang Qiang, a greening engineer in Weidun Park, prescribes the right medicine for these plants with a high rate of appearance in the home, providing a detailed guide to safety in the summer.

The gentleman orchid preferred by presbyopia: pay attention to the rotten roots.

The appearance rate of gentleman orchid in the homes of Changzhou citizens has been very high, and it has a very long history of breeding, so it is deeply loved by presbyopia. Wang Qiang said that high temperatures and days of rain in summer are the high incidence period for the rotten roots of gentleman orchids. To prevent the rotting root of the gentleman orchid, it is necessary to avoid waterlogging and water soaking for a long time in summer. Fertilizing should use fermented organic fertilizer, appropriate amount, thin fertilizer applied frequently. If the rotten root is found, it is necessary to remove the rotten root in time and disinfect the root.

"to rescue rotten roots, we must first pour out the whole plant, remove and cut off the rotten roots, then coat the wound with charcoal powder or fine furnace ash (it can also be rinsed with potassium permanganate water), put it in the sun for about 10 minutes, and use ultraviolet light to disinfect and sterilize." Wang Qiang said that if the roots have rotted more than half, they can be put into fine sand to promote the roots. If only a few roots rot, they can be transplanted into the nutritious soil that has been replaced, and watering can be controlled within half a month, and can be restored after a month or two.

Green pineapple essential to many families: beware of yellow leaves

Green pineapple is very easy to raise and is one of the necessary green plants in many citizens' homes. Wang Qiang said that the leaves of green pineapple, which are common in ordinary residents' homes, turn yellow in summer. on the whole, green pineapple leaves turn yellow. if they are cultured in water, there are bacteria in the water, and if they are cultivated in soil, their roots may be rotting. Relatively speaking, the probability of yellow leaves in hydroponic green pineapple is higher than that in soil culture.

"the specific factors for the yellowing of green radish leaves are improper watering, unbalanced light, incorrect fertilization and so on." Wang Qiang said that too much or too little watering will cause the green apple to turn yellow. If the leaf surface is dark and yellow without luster, the new shoot shrinks not long, it may be too much watering, and if the leaf tip or edge is withered and dried, the new leaves grow normally, but the old leaves are withered and yellow and fall off is underwatered.

Secondly, green pineapple likes shade, strong light exposure will cause the tip and edge of flowers to wither, and the sunrise part of the leaves will appear macula; on the contrary, if the leaves are placed in a dark environment for a long time, the leaves will not get enough sunlight and can not form chlorophyll. it will also cause green radish leaves to turn yellow and need to replenish light in time.

It is crucial to do these three details well this season.

"in addition to the three misunderstandings mentioned above, there are three key details." Xu Yi said that most plants will be dormant or semi-dormant in summer, which is a bit "delicate", and the three details of reasonable watering, lighting and ventilation and pest control are particularly critical.

"the first is watering. The best watering time is before 10:00 and after 4pm every day. If the temperature is above 30 ℃, try to reduce the watering of plants." Xu Yi said that if it is placed on an outdoor platform or hard ground, it is usually watered once a day, according to the actual situation, appropriately increase the watering times and amount of water, or spray water on the foliage surface to achieve the effect of humidification; if it is an indoor foliage plant, it does not need to be watered every day, see that the basin soil is dry and then water through, and pay attention to foliar spraying.

In terms of lighting and ventilation, too much Rain Water and too strong light are not conducive to the growth of indoor flowers, but ventilation conditions are essential. Lighting can be arranged according to the characteristics of domestic plants, such as rose, bowl lotus and other strong positive flowers must have sufficient light, while rich trees, green pineapple, evergreen and other neutral or negative plants can appropriately lower the light requirements.

In terms of pest control, the plum rain season is the season of frequent occurrence of potted flower diseases and insect pests, and the most common pests are red spiders and aphids. Affected by high temperature and heavy rain, plants are easily infected by fungi, and diseases such as black spot and powdery mildew occur from time to time. Considering the safety of drug use, low-toxic insecticides or fungicides in small packages can be purchased in the market according to the instructions, and attention should be paid to the alternate use of pesticides.

Third, too much fertilizer, too much concentration, or no lack of fertilizer may cause the green gong leaves to turn yellow. when applying too much fertilizer, the green gong leaves are thick and without luster, and the leaves are not stretched, and the old leaves are yellow. When there is a lack of fertilizer, the color of the leaves will become lighter, showing a light green or yellow shape, need to supplement fertilizer, seriously important to change the basin soil.
