Culture methods of Mulberry Leaf Peony

Mulberry leaf peony is a famous flower in China, also known as Fusang, hibiscus, hibiscus, etc., is an evergreen shrub of the hibiscus genus of Malvaceae, although the flowers bloom continuously, the flowering period is long, and the summer and autumn flowers bloom the most. The cuttings of the same year can blossom in the second year. Coupled with simple management, they have become important indoor flowers. Let's take a look at the cultivation methods of mulberry peonies.

Growth habits of mulberry leaf peony

Mulberry leaf peony is a strong positive plant, which likes to be warm and humid, and requires sufficient sunlight, no shade tolerance, cold and drought tolerance. In the Yangtze River valley and the north area, it can only be potted and keep the temperature of 12: 15 ℃ in greenhouse or other protected areas to survive the winter. When the room temperature is lower than 5 ℃, the leaves turn yellow and fall off. If it is less than 0 ℃, it will suffer frost injury. Resistant to pruning and strong branching. It can adapt to a wide range of soil, but the slightly acidic loam rich in organic matter and PH6.5~PH7 grows best.

Propagation methods of Mulberry Leaf Peony

1. Cutting propagation: cutting is the most commonly used method for mulberry leaf peony propagation, which can be cut at any time from early spring to late autumn, with the highest survival rate in the rainy season and can only be carried out in the greenhouse in winter. The best cuttings are one-and-a-half Lignification, about 10 cm long, cut off the lower leaves, leave the top leaves, cut flat, insert in the sand bed, spray water every day to maintain high air humidity. It takes root three weeks after insertion and can be put on the pot after 45 days of growth. Generally speaking, the mulberry leaf peony cut in that year can blossom in the second year.

2. High-pressure propagation: high-pressure propagation is mainly aimed at woody branches, which is commonly used in woody plant species. Mulberry leaf peony can also give it a try, which is safer than cutting high-pressure propagation, at least it will not die.

3. Striping propagation: striping propagation is to press the branches of mulberry peony in the soil, let them take root, and cut off after taking root, the principle is similar to high pressure, but there are slight differences according to the actual situation. These three methods are all very simple and operable, and flower friends can give it a try.

4. Seed propagation: Mulberry leaf peony page can be propagated by seed, but because of the particularity of floral organ structure, especially indoor cultivation, the seed setting rate of natural pollination is almost zero, so artificial pollination is needed. The seed setting rate of artificial pollination is 2-5%, and it is difficult for seeds to germinate. Because the seed coat is very thick and hard, it is not easy for seeds to germinate. Soaking seeds in the temperature range of 20-25 ℃, there is plenty of oxygen, and it takes about 30 days to germinate.

Culture method of Mulberry Leaf Peony

1. Soil selection and basin change: loose and fertile sandy loam should be selected for mulberry peony potted soil, and pots should be changed before moving out in early spring and April every year. When changing the basin, there are three things to do: one is to replace the new culture soil, the second is to cut off part of the overdense curly fibrous roots, the third is to apply sufficient base fertilizer and slightly add phosphate fertilizer to the bottom of the basin.

2. Shaping and pruning: Mulberry leaf peony can be pruned and shaped before and after leaving the room in early spring according to the strong ability of sprouting and tillering in order to keep the tree shape graceful. The upper part of each branch is all cut except for 2-3 buds at the base. Pruning can promote new branches, grow more vigorously, and the plant shape is also beautiful. After pruning, due to the reduction of aboveground consumption, it is necessary to properly control water and fertilizer.

3. Out-of-room management: the positive tree species of mulberry leaf peony should be moved to the outdoor and placed in a sunny place at the beginning of May, which is also the growing season of mulberry leaf peony, so it is necessary to strengthen the management of fertilizer and water, loosening soil and pulling grass. Apply dilute liquid fertilizer every 7-10 days, watering should depend on the dry and wet condition of the basin soil, 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.

4. Enter the room in time: Mulberry leaf peony is not resistant to frost. It must be moved into the room to keep warm after Frosts Descent and the Beginning of Winter. The overwintering temperature should not be less than 5 ℃ to avoid freezing injury and not higher than 15 ℃ so as not to affect dormancy. Poor dormancy, poor growth and blossom in the following year. Furniture houses with good thermal insulation conditions facing south can survive the winter and can be covered with 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.

5, humidity management: too dry and wet will affect flowering, in the summer blooming season, depending on the air temperature and basin soil dry and wet conditions, watering 1 or 2 times a day, but to achieve dry and thorough irrigation to prevent rotting roots due to high temperature and stagnant water. Watering is better before 9: 00 a. M. or after 5: 00 p. M. to minimize the temperature difference between air temperature and water temperature. At noon, water can be sprayed on the leaf surface and around the flowerpot to reduce the leaf temperature and maintain air humidity. Mulberry peony flowers are very tender, can not spray water directly to the flowers, otherwise it is very easy to cause flower burns.
