Culture methods and matters needing attention of cyclamen what to do with yellow leaves and curls

Cyclamen itself looks like a fairy, is very good-looking, many people want to breed, cyclamen breeding methods and points for attention what are there? In the process of breeding, there are yellowing leaves in the hair curls how to do?

Cyclamen culture methods:

Cyclamen prefers cool, moist, sunny and ample environment. The suitable temperature for growth and flower bud differentiation is 15 ℃ 20 ℃, and the humidity is 70%-75%; the temperature during flowering in winter should not be lower than 10 mol. If the temperature is too low, the flower color will be dim and easy to wither; if the summer temperature reaches 28 ℃ and 30 mol, the plant will dormancy, and if it reaches more than 35 mol, the tuber is easy to rot.

The seedlings of cyclamen were slightly more resistant to heat than the old ones. For Chinese and Japanese plants, the suitable light intensity in the growing season should not be too strong, and it can be a little more in winter. It requires slightly acidic sandy loam which is loose, fertile, rich in humus and well drained. The florescence is from October to April of the following year.

Points for attention in cyclamen culture:

When cyclamen is cultivated, the soil should be loose, and it can be used as a mixture of 2 rotten leaf soil, 1 garden soil and a small amount of calcium superphosphate. You can also use sun-dried or broken river mud, or a mixture of 2 parts of peat and 1 part of perlite. The cultivated soil needs to be fumigated.

When changing pots, depending on the size of the plant, gradually increase the flowerpot, should not directly use large pots to cultivate small seedlings. It should be planted shallowly when planting.

When the big seedlings are potting and changing pots, they should make the ball 2, 3, 3, 1 and 2 live on the soil surface, so as to prevent the ball from wet rot in the soil. Avoid applying thick fertilizer, which is easy to hurt the root. Topdressing can be about 3 times a month, before fertilization, it is appropriate to loosen the soil, to choose clear days to apply fertilizer, fertilizer should not be applied from the top of the plant, should be applied on the side, and should be washed by spraying water after fertilization.

Causes and treatment of cyclamen leaves yellowing:

1. Lose weight for a long time

There is no application of nitrogen fertilizer or no change of water for a long time, and the lack of nitrogen and other nutrient elements in the water leads to thin branches and leaves and thin and yellow leaves. It is necessary to change into new culture water in time and gradually apply rarefied mature liquid fertilizer or compound flower fertilizer.

2. Excessive fertilization

If you fertilize too much, the new leaves will be thick, and the old leaves will be rugged, and the dry tips of the old leaves will fall off. You should immediately stop fertilization, increase the amount of water exchange, make the fertilizer lose, or immediately pour the pot, rinse the bulb root with water and then plant it again into the basin.

3. Hot and high temperature

If you put the daffodils in a high temperature and let the strong light shine directly, it is very easy to cause the leaf tip and edge of the young leaves to scorch, or the leaves yellow to fall off. Move to a well-ventilated shady place in time.

4. Excessive shade

If the daffodils are kept in shade or lack of light for a long time, it will cause the branches and leaves to turn yellow.

5. Alkali in soil and water.

If there is a lack of soluble iron and other elements that can be absorbed by it in the growth environment, the leaves will gradually turn yellow. Acid soil and water should be selected when planting, and alum and fertilizer water should be often irrigated during the growth period.

5. Whether it is ventilated or not

If too much nitrogen fertilizer is applied, the branches and leaves will grow luxuriantly, coupled with the long-term unpruned, resulting in insufficient light in the inner chamber branches and leaves, which is easy to cause the leaves to yellowing and falling off. Reasonable fertilization should be applied and pruning should be strengthened to make it ventilated and transparent.

6. Air drying

When the indoor air is too dry, daffodils often appear phenomena such as leaf tip dryness or leaf edge scorching. Attention should be paid to water spraying, plastic film cover and other methods to increase air humidity.

Cyclamen leaves curled and yellowed:

Solution:

Lack of nutrition, pay close attention to fertilization, to the florist to buy special fertilizer can not be too much to supplement the nutrition of flowers, usually a small number of pots can bury some cooked soybeans, cooked peanuts. Bean cakes, changed steamed buns, etc., so as not to worry about lack of nutrition (can reply: life fertilizer).

Cyclamen has rotten stems and yellowing leaves:

Solution:

Too much water. Stop watering until it heals and the soil dries.

If you water too much, the leaves will turn yellow, but if you water less, the buds will wither.

When the summer temperature is high, cyclamen will go dormant.

Watering as little as possible during dormancy, just keep the soil moist to prevent the roots from rotting away due to too much water. When planting, it is advisable to expose the bulbous roots of flowers to 1/3 of the soil.

When watering, water directly in the flowerpot, flowers and leaves as far as possible do not touch water, because cyclamen leaves are round and concave in the middle, it is easy to store water, it is not good to leave water marks after evaporation.

For a long time, the foliar breathing is not smooth, it is easy to dry and yellowing, affecting the ornamental, it is best to wipe with a soft cloth. When watering, you should see it dry and wet once, and you can't water it every day, because cyclamen has the function of storing water and watering more water, it is easy to produce flower buds. The leaves turn yellow and dry every three days in spring and once every five days in autumn.

The leaves are yellow and dry:

Solution:

Cyclamen is also yellowing and drying up is mainly caused by the poor air permeability of the basin soil and the over-drying of the basin soil. The soil with better permeability can be changed when the air temperature is 15-25 ℃, and the water should be fed from the bottom, and the basin soil can be watered only when the basin soil is dry, and the water temperature is close to room temperature.

Cyclamen pest control:

The main diseases and insect pests of cyclamen are root rot, soft rot, aphids and scale insects.

Root rot disease

Root rot is a seedling disease, root water stains, softening rot, wilting and withering of diseased seedlings.

Prevention and control measures:

1. Soak the seeds in 0.1% copper sulfate solution for half an hour for disinfection.

2. Before sowing, spray potassium permanganate 1800-2000 times solution to disinfect the soil.

3. Strengthen ventilation, control humidity, properly release air and cultivate seedlings to enhance resistance.

4. In the early stage of cripple disease, 72.2% Pulicol water agent, 50% Likujing and 40% Gen Funing 1000 times solution can be sprayed or irrigated.

Soft rot

The leaves produce waterlogged disease spots, and then soft rot, overflow of white bacteria, plant wilting and death.

Prevention and control measures:

1. Remove diseased leaves and diseased plants.

2. Control watering and pay attention to ventilation.

3. Spray control with 50% carbendazim wettable powder 1000-2000 times liquid.

Aphids

It harms young leaves and buds, forms galls, induces coal fouling disease and spreads virus.

Prevention and control measures:

1. Prevention and control of natural enemies such as ladybugs and lacewings.

2. Set up armyworm board to trap or cover with plastic film to avoid aphids.

3. Alternate spray control with 2000 times solution of 50% aphid fog wettable powder and 10% imidacloprid 1500 times solution.

Shell worm

Harm leaves and flowers.

Prevention and control measures:

1. Get rid of the infected plants in time.

2. Spray 10% imidacloprid EC 1000 times or 25% Fen Jieling 1500 times for prevention and control.

Cyclamen breeding methods and problems in the breeding process are introduced here, do not hurry to a cyclamen at home.

How to raise cyclamen, the breeding methods and precautions / temperature of cyclamen are the most important.

Cyclamen, also known as poinsettia, is very similar to the name of poinsettia. It is a beautiful, magnificent and brightly colored flower. In modern times, keeping cyclamen indoors is the first choice for many people, but they can't raise it, so how to raise potted cyclamen? Soil, light, etc., are essential, but watering is also critical. The following are the breeding methods and precautions of cyclamen. Friends who want to raise them must have a look.

First, how to raise cyclamen, temperature is the key

Take cyclamen to indoor potted plants, without the advantages of nature, in order to raise it well, we need to be prepared in the soil, light, watering, temperature and so on, especially the temperature, must reach the standard. In addition, how cyclamen is raised, we also need to pay attention to many places. Here are the breeding methods and precautions of cyclamen. Let's move on.

2. Breeding methods and matters needing attention of cyclamen

1. The soil is loose and fertile

The culture soil of cyclamen can be prepared with 3 parts of humus soil, 2 parts of forest rotten leaf soil, 2 parts of furnace ash, 2 parts of river sand (sandy vegetable garden soil), 1 part of mature compost, and adding appropriate amount of calcium carbonate and other chemicals. This kind of soil is loose and fertile and suitable for cyclamen growth.

Note: when potted, the cultivation soil must be disinfected at high temperature strictly by the method of fumigation, and the cultivation container should be gradually enlarged according to the size of the bulb, and the seedlings should not be cultivated in large pots.

2. Light and temperature

In cyclamen culture methods, light and temperature are very important. In the whole growth process, it is mainly from the temperature to consider prolonging the florescence. From April to August, the light and temperature of cyclamen should meet the following requirements:

① after the flowers are reduced by the end of April, the potted flowers should be removed from the greenhouse and kept in a well-ventilated and cool place with scattered light.

② leaves all withered in July to the hottest period, to put the flowerpot in a low-temperature, ventilated environment, the pot soil should not be too dry, let it dormancy for a month.

After August, ③ placed cyclamen in the temperature and light environment suitable for growth, and watered it slightly, so that the bulbs could sprout as soon as possible, and cyclamen could sprout in advance.

④ turned the basin and changed the soil at the end of August to cut off the abortive roots so as to make the plants grow vigorously under good ecological conditions.

Note: the suitable growth temperature of cyclamen in winter is 10: 22 ℃, and the temperature difference between daytime and night should be 8: 10 ℃. It can also bloom when the night temperature is controlled at 7: 8 ℃, but the florescence will be delayed slightly, but if it is lower than 6 ℃, it can not blossom normally. In summer, conditional cooling equipment should be used to lower the ambient temperature.

3. Watering method

Cyclamen can withstand drought, but it is best to keep the soil moist during its growing season and be careful not to accumulate water in the basin. Cyclamen does not like soil that is too wet. Watering should be frequent and less, not too wet. If the summer is not dormant, normal watering can be carried out, and the basin soil needs to be kept sweet and moist.

Note: after the Beginning of Autumn, cyclamen enters the period of human reproductive growth, at this time to apply phosphorus and potassium fertilizer. If it is found that the plant is overgrown, apply calcium superphosphate or plant ash extract to control vegetative growth. promote flower bud differentiation, bud pregnancy and flowering.

4. Fertilizing, not fond of thick fertilizer

Cyclamen like fertilizer, but do not like thick fertilizer, in addition to turning the basin to change the soil to apply some basic fertilizer, generally can be fertilized once every ten days and half a month, pay attention to thin fertilizer diligently. After planting, during the vegetative growth period for several months, organic liquid fertilizer can be applied with a concentration of 1, 6, 1, 8, 1 and 10, and the flowers can be watered with muddy water.

Note: stop fertilizing when you can't control the temperature in summer.

Matters needing attention in the breeding of cyclamen

Although in the above cyclamen breeding methods, there are many points for attention, but if you want to raise cyclamen, there are many places that flower friends need to pay attention to, such as spending the summer. When the summer temperature exceeds 28 ℃, cyclamen seeds will begin to dormancy, the dormancy period is not well managed, and the bulbs are easy to dry or rot, so it is difficult for cyclamen cultivation to spend the summer safely.

It is the best way to spend the summer with strong seedlings. The annual seedlings sown have vigorous growth and weak dormancy tendency in summer. it is necessary to strengthen fertilizer and water management before the beginning of summer to form strong seedlings so as to make the leaves thick, many leaves, thick color and luster. This kind of seedling has strong heat resistance, and it is necessary to do a good job of cooling and dampness reduction at the same time. Cover the sunshade net, increase ventilation, apply thin fertilizer frequently, and spray water around the plant to cool down. After spending the summer in late August, cyclamen enters the growing period, so it is necessary to strengthen fertilizer and water management.

For more than two-year-old balls, they should also be moved to shade and rain shelter in summer, and often spray water around to cool down, strictly control the watering in the basin, rather dry than wet, generally pour 2-3% water into the dry basin for about 10 days, never be flooded or caught in the rain, otherwise the bulbs will rot. Until early September, gradually resume watering, two or three weeks later, can be moved to the sun, and normal application of fertilizer water, during the Spring Festival can blossom as scheduled.

After the cyclamen leaves fall off completely, dig out the bulbs, remove the soil and dead leaves, store them in a cool and ventilated place indoors, put them back into the basin after autumn, and apply fertilizer and water reasonably to restore vitality. Cyclamen breaks dormancy but artificially creates a cool environment, such as in an air-conditioned room. Keep the temperature at 20-30 ℃ and water it normally, cyclamen will continue to grow, sprout new leaves and produce new flowers. The original environment will be restored after autumn.

What if the cyclamen leaves turn yellow? Cyclamen culture methods and precautions detailed explanation of cyclamen flower language has the meaning of welcoming distinguished guests, in fengshui has the meaning of "cyclamen floated to", is a symbol of auspiciousness. Cyclamen, also known as radish and begonia, is a crown. The flowers and colors are white, red, purple, orange-red, red-edged and white-hearted, and some of them are fragrant. The flowering period can last as long as half a year, and they are very popular.

When maintaining cyclamen, flower friends often encounter problems such as yellow leaves, moldy leaves, rotten stems, dim flowers and so on. So how can we raise cyclamen well? Next, let's learn the maintenance methods of cyclamen together with the blue demon. First, seed selection and seedling raising. 1. Seed selection cyclamen family planting often adopts the method of sowing and breeding. Seed selection should choose the brown seeds harvested in the same year, full, glossy and free from diseases and insect pests.

2. Sow the seeds in the mixture of gibberellin of 50ppm and methyl thiophanate or chlorothalonil of 500ppm for one day and night, then control clean water, rinse in clean water, and control water to dry the surface moisture. Then sow the seeds, and the florescence of the soaked seeds is about 10 days earlier than that of the unsoaked seeds. The sown soil requires good ventilation, mixed with peat and perlite in a certain proportion, the PH value is 6-6.5, the humidity is moderate, and it should not be too wet. Cyclamen germination temperature is about 18 ℃, the germination period does not need light, after sowing with vermiculite or perlite cover, thickness is just enough to cover the seeds, and covered with plastic film. 3. After sprouting management seeds, shading net should be used to shade properly, or the seedling pot should be covered with non-woven cloth to maintain seed humidity. The relative humidity is controlled at about 85% and can be sprayed if necessary.

4. Water and fertilizer management at seedling stage. Watering at seedling stage should not be flooded, and sprinkler should be applied close to the soil surface. The temperature of watering should be controlled above 14 ℃. According to the growth of seedlings, fertilizer should be applied from the fifth week after sowing, the ratio of nitrogen: phosphorus: potassium is 1:1:1, the leaves of seedlings should be glossy, if dark red, fertilizer should be applied. 5. Transplanting seedlings in the upper pot can be carried out 10-11 weeks after sowing. Cyclamen is easy to rot because of stagnant water, so it is best to choose sandy soil or other soil with good permeability and water permeability. It can be mixed with peat plus a certain proportion of garden soil and perlite, and the PH value is 6-6.5.

The transplanting soil just covers the root system, leaving the bulbs exposed. Do not press the seedlings or the surrounding soil with your hands. If the relative humidity is controlled between 65% and 85%, the humidity can be increased by spraying. Second, planting points for attention: if you buy cyclamen directly, you need to decide the specific planting method according to the season when planting. Because cyclamen has the characteristics of summer dormancy, if the time to buy the ball is summer, it is mainly to spend the summer. If the ball is bought during the growing period, it can be cultivated normally and wait for germination. When burying the ball, you should expose the planting ball to the soil, or expose the bud point to the outside.

If it is in summer, usually after May, cyclamen has already begun to dormancy, so when planting, you must not pour the basin soil thoroughly, but plant it when the basin soil is slightly wet, and then put cyclamen in a cool and ventilated place. Every now and then look at the dry and wet condition of the soil, if it is dry, just sprinkle a little bit of water and keep the soil slightly moist, which will continue until the weather turns cooler, cyclamen will sprout, and then transfer to normal maintenance.

Not all cyclamen can wake up after summer dormancy, which is closely related to the quality of planting balls and the preservation environment. When the autumn temperature is cool, it will be below 25 degrees, thoroughly watered and awakened (sometimes naturally). Third, cyclamen daily maintenance 8 key points: 1, bought cyclamen do not have to rush to change pots, the flowering period will not grow very big in half a year. 2. If the leaves are too luxuriant, it is recommended to remove them properly. 3. Continue to fertilize after budding. If you want flowers to be strong, nutrition must keep up with 4. Watering must be thorough. Generally bought cyclamen to use the soil is nutritious soil (beneficial to raising seedlings). The water permeability is excellent, and it will leak as soon as it is watered. In fact, it may not be thoroughly watered. It is best to soak the basin for a while, so that the flowers and leaves can absorb enough water before they are tall and straight; (be careful not to water the flowers) 5, do not need strong light, put indoor astigmatism ventilation 6, flowering can help pollination, easier to seed. Of course, sowing and cultivation requires patience 7, cyclamen winter flowering temperature should not be lower than 10 ℃, if the temperature is too low, the flower color is dim, and easy to wither 8. Cyclamen summer temperature reaches 28 ℃ 30 ℃, then the plant dormancy, if more than 35 ℃, then the tuber is easy to rot.

Fourth, cyclamen breeding points in each month: November-March is cyclamen flowering season, potted flowers should be placed in front of the south window or south closed balcony 1 meter in front of the light. When the room temperature is more than 10 ℃, keep the basin soil moist and pour 1 ‰ potassium dihydrogen phosphate foliar fertilizer once a month, it can blossom continuously. In a room without heating facilities, you should pay attention to prevent low temperature and cold wind. You can cover it with a transparent plastic bag in a basin and put it in a warm and bright place. Open the plastic bag to get some air when the temperature is high at noon. It can blossom from February to March. When watering, pay attention to the water temperature and medium temperature as close as possible, it is appropriate to choose at 10:00-12:00, and water do not stick to flower buds and tender leaves, so as not to rot and affect flowering.

April-May April-May cyclamen florescence is coming to an end, it is necessary to cut off the residual flowers as soon as possible and gradually put them in the outdoor sun. If the compound fertilizer solution of 1 ‰ is poured once a week, the new leaves will grow quickly, the old leaves will fall off, and the corms will grow larger. If aphids occur, you can use brushes or cotton swabs dipped in water brushes to eliminate; if leaves are found to shrink and turn yellow, carbofuran 1g can be buried along the edge of the basin to eliminate root-knot nematodes.

The water and fertilizer management of cyclamen in June is the same as in May. Keep it in the shade when the temperature is high. Some potted flowers fall their leaves and enter dormancy after flowering until September. At this time should be placed in a cool and ventilated place, keep the basin soil slightly wet, do not fertilize. From July to August, it is the high temperature season in the north, so water should be controlled and fertilizer should be stopped. Undormant plants should be placed on the east or north balcony, bask in the sun for more than an hour every morning, or in the shade of trees. At this time, new leaf buds and flower buds grow at the top of the bulb. In case of rot (Botrytis cinerea), 1000 times of chlorothalonil wettable powder can be sprayed and irrigated.

Cyclamen dormant bulbs begin to sprout in September. The old plants of more than two years can be changed, and the newly purchased bulbs can also be planted at this time. When planting, first pad 2cm thick charcoal slag or ceramsite, coarse gravel at the bottom of the basin, and then add culture soil. The old plant should be planted with soil. After planting, the potted surface should be high in the center and low around it. The bulb should be exposed to the soil at 1 / 2. Water should be thoroughly watered the next day and maintained in a shady place. The light can be increased after the new buds grow.

Entering the vigorous growth period in October, it should be maintained in the sun. The foliar fertilizer of 1 ‰ potassium dihydrogen phosphate was sprayed once a week with compound fertilizer solution of ‰. Frosts Descent moved into the room before. It will blossom in November.

Fifth, cyclamen common maintenance problems: symptom one: cyclamen leaves curling and yellowing. Reason: lack of nutrition, we should pay close attention to fertilization. Solution: you can buy special fertilizer from the florist. But do not add too much nutrition to flowers, usually a small amount of cooked soybeans, cooked peanuts, bean cakes, changed steamed bread and so on, so that you do not have to worry about cyclamen lack of nutrition.

Symptom 2: the flower stem of cyclamen is rotten and the flowers and leaves are yellow. Reason: too much water. Solution: stop watering, wait until the leaves of cyclamen are not yellow, and the soil is dry before watering. And watering should be supplied from the bottom, the basin soil can only be watered when it is dry, and the water temperature is close to room temperature.

Symptom 3: the leaves turn yellow when watered, and the buds that just grow out of less water wither. Reason: dormancy solution: cyclamen can bloom twice a year, mainly in spring and autumn. Cyclamen likes half shade, so don't shine directly in the sun. With the high temperature in summer, cyclamen is going to go dormant. Water as little as possible during dormancy and keep the soil moist to prevent the roots from rotting off due to too much water.

Symptom 4: cyclamen leaves turn yellow. Reason: the yellowing of cyclamen leaves is mainly caused by the poor air permeability of the basin soil and the over-drying of the basin soil. Solution: when the temperature is 15-25 degrees, cyclamen can be replaced with better breathable soil.

Symptom 5: the color of cyclamen flowers is getting lighter and lighter. The reason: cyclamen flowers are getting lighter and lighter is mainly related to insufficient light and insufficient fertilization. Nowadays, most cyclamen sold in the flower market apply special fertilizer before going on the market, and the watered water is also softened water, so the cultivated flowers are particularly gorgeous. Solution: improve the light of cyclamen, apply cyclamen special fertilizer every half a month, and try to use pure water or plain boiled water that has been cold for two days.
