Mulberry leaf peony is Fusang, also known as hibiscus, hibiscus. As an evergreen shrub, it is a famous flower in China with large flowers and many colors. Although the flowers are blooming and falling, they are continuous, with a long flowering period and the most blooming flowers in summer and autumn. What are the breeding methods and matters needing attention of mulberry leaf peony? What if the leaves turn yellow?

Culture methods and matters needing attention of Mulberry Leaf Peony

1. Soil: it can adapt to all kinds of soil, but the fertile and loose weak acid soil is the best.

Land selection and preparation: weak acid soil with sunny, warm and humid climate, fertile soil, loose drainage and good drainage.

2. Temperature: the optimum temperature for the growth of mulberry leaf peony is 15-25 ℃ and 13-18 ℃ from October to March of the following year. The winter temperature should not be lower than 5 ℃, otherwise the leaves turn yellow and fall off. It is easy to suffer frost damage when the temperature is lower than 0 ℃, but it can still grow normally at high temperature above 30 ℃.

It must be moved indoors after Frosts Descent and before the Beginning of Winter, because mulberry leaf peonies are not resistant to frost. The overwintering temperature is not lower than 5 ℃ to avoid freezing injury, and not higher than 15 ℃ to avoid affecting dormancy. Cover paper or plastic film to keep warm when the weather is colder. The first moving room should open windows every day for ventilation, pay attention to the dry and wet changes of the basin soil, and water properly. In the coldest weather, watering can prevent frost injury, but fertilization should be stopped.

3. Sunshine: Mulberry leaf peony is a strong positive plant, and sufficient light is needed during the growing period in order to grow and bloom normally. If the light is insufficient, the bud is easy to fall off, the flower is small and the color is dim, but when the sun is too strong, the plant will burn, so it should be protected by shade properly.

4. Watering: keep the basin slightly moist during the winter. generally, the amount of water watered every 5 to 10 days should not be too much, so as to avoid root rot caused by low temperature and high humidity. The dry climate in northern winter will appear the phenomena such as yellowish leaf color and dry leaf edge, so we should pay attention to improve the indoor air humidity. Spraying and washing branches and leaves or covering plastic film can be used to increase the air humidity around the plant to create suitable humidity conditions for its growth.

5. Management: management is also very important. When you want to move outside and put it in a sunny place at the beginning of May, it is necessary to strengthen the management of fertilizer and water, loosening soil, pulling grass and so on. Apply dilute liquid fertilizer every 7-10 days, pay attention to the dry and wet condition of the basin soil when watering, too dry or too wet will affect flowering. Post-autumn management should be cautious, pay attention to less fertilization in the later stage, so as to avoid the emergence of autumn shoots. Autumn shoot tissue is young, cold resistance is weak, cold weather will suffer frost damage.

6. Change the basin: the basin should be changed before moving out of the house in April every year. Loose and fertile sandy soil should be selected. When changing the basin, we should also replace the new culture soil, cut off part of the overdense curly fibrous roots, apply sufficient base fertilizer, and slightly add phosphate fertilizer to the bottom of the basin.

7. Pruning: after being moved outside, pruning is carried out. Except for 2-3 buds at the base, all the branches are cut at the top. Pruning can promote the development of new branches, which will grow more vigorously and the plant shape will also be beautiful. After pruning, water and fertilizer should be properly controlled.

8. Prevention and control of diseases and pests: after entering the room in winter, if the indoor ventilation is poor and the light is insufficient, it is easy to be harmed by aphids and shell insects. Attention should be paid to improving the ventilation and light transmission conditions of the indoor environment combined with drug control. A small amount of shell worms can be gently brushed off with a brush. The main pests of mulberry leaf peony are aphids, chaff, cotton blowing medium and mites (commonly known as red spiders). These pests are all prick-sucking pests. That is, they use their mouthparts to pierce the leaves or epidermis of plants to absorb plant juice. The leaves of the killed plants lost green and grew weakly, which reduced the ornamental value. After the occurrence of aphids and mites, aphids and mites can be diluted by a certain number of drugs, such as aphids and mites, and then foliar spray can be used to kill aphids and mites once a week, usually 2-3 times. Bran medium and cotton blowing medium can harm leaves and epidermis. Generally, imidacloprid drugs or their modifiers can be used to dilute a certain number of times, and then spray to kill the affected parts. The harm is serious, but once every 10 days, 3 times can be basically extinct.

What reason is mulberry leaf peony leaf yellowing? What shall I do?

1. Yellow leaves are caused by too low temperature.

Mulberry leaf peony is a strong positive plant, the sun should be sufficient, the temperature should not be too low, cold in winter is easy to be frostbite and leaves yellow fall off.

Solution: if the potted plant can be moved indoors, if the room temperature is also very low, you can cover the pot with a plastic film, pay attention to basking in the sun as much as possible, and keep the basin soil dry, so as to ensure that it will not be damaged by freezing. If it is cultivated in the open field, you can also cover transparent plastic film or do other heat preservation measures.

2. Yellowing of leaves caused by sudden changes in the environment

For example, after the winter, it is urgent to move the mulberry leaves outside and put them in a place much warmer than indoors, coupled with sun exposure, which will result in falling leaves unable to adapt to the abrupt environmental conditions.

Solution: Mulberry leaf peony environment temperature, light and other conditions can not change too much, there should be an excess, you can move out of the indoor and outdoor again in warm spring or early summer.

3. Yellow leaves caused by improper watering

The yellowing of mulberry peony leaves may also be caused by improper watering. Stagnant water or over-drying will cause the leaves to turn yellow or even fall off.

Solution: if the basin soil is too wet, dry the basin soil before watering, because it likes the air temperature to be slightly higher than the moisture content of the basin soil; if it is too dry, it should be watered in time, and pay attention to the amount of water and frequency of watering.

4. Yellow leaves are caused by alkaline soil.

The slightly acidic loam of PH6.5~PH7 is the best and most favorable for its growth. If the basin soil is alkalized, it will cause its leaves to yellowing or even fall off.

Solution: change the basin soil, change the hardened or alkalized soil into acid soil, and pay attention to apply acid diluent regularly when watering in the north to prevent basin soil from alkalization.

5. Lack of light or poor ventilation can also cause yellowing of leaves.

Mulberry leaf peony is a sunny plant, sunshine can not be less than 8 hours a day, otherwise it is easy to cause yellow leaves, if the ventilation is poor, it is also easy to cause leaves yellowing.

Solution: plant or put it in a sunny and well-ventilated environment.

[tip] if the leaves of potted mulberry peonies are not washed with water for a long time, then the photosynthesis of the leaves will be hindered by the accumulation of dust. this situation will also lead to the yellowing and falling of the leaves, so we must pay more attention to daily maintenance. in addition, remember to prune in spring, leaving stout branches can make nutrients more concentrated and bloom more vigorously in summer and autumn.

Mulberry leaf peony is a flower that blossoms in summer, and many flower lovers do not know how to maintain it when they are cultured, resulting in the phenomenon of falling buds during flowering. How to deal with this situation? what are the ways to let mulberry peony blossom more?
