1. Choose soil and change pots: loose and fertile sandy loam should be selected for potted soil in mulberry leaf peony, and pots should be changed before moving out in early spring and April every year. There are three things to do when changing pots: first, put in new culture soil; Second, cut off some fibrous roots that are too dense and curly; Third, apply sole fertilizer and slightly add phosphate fertilizer to the basin bottom.

2. Trimming: In order to maintain a beautiful tree shape and a large number of flowers, mulberry leaf peony can prune and trim before and after leaving home in early spring according to the characteristics of strong sprouting ability of branches. Except for 2 ~ 3 buds at the base, all branches are cut off. Pruning can promote the new branches to grow more vigorously and the plant shape is beautiful. Water and fertilizer should be properly controlled after pruning, because the consumption of aboveground parts is reduced.

3. Outdoor management: The positive tree species in mulberry leaf peony should be moved outdoors in early May and placed in sunny places. At this time, it is also the growing season in mulberry leaf peony, so we should strengthen the management of fertilizing water, loosening soil and pulling weeds.

Apply dilute liquid fertilizer every 7 ~ 10 days, and water it according to the wet and dry conditions of the basin soil. Too dry or too wet will affect flowering. Management should be cautious after autumn, and pay attention to less fertilization in the later period to avoid sprouting autumn shoots. Autumn bamboo shoots are tender and weak in cold resistance, and will be frozen when the weather is cold.

4. Enter the house in time: mulberry leaf peony is not frost-tolerant, so you must move indoors to keep warm after the first frost and before beginning of winter. The overwintering temperature should not be lower than 5℃ to avoid freezing injury, and not higher than 65438 05℃ to avoid affecting dormancy. Poor dormancy leads to poor growth and flowering in the following year.

All furniture rooms with good heat preservation conditions facing south can survive the winter, and can be covered with paper or plastic film for heat preservation when the weather is cold. Move the house for the first time every day, open the window for ventilation, pay attention to the dry and wet changes of the basin soil, and water it properly. In the coldest days, watering can prevent freezing injury, but fertilization should be stopped.

Matters needing attention in mulberry leaf peony aquaculture:

1, because mulberry leaf peony is a sunny flower, it should be placed in a place with long sunshine, so that it can fully receive sunlight, and it can be fully illuminated in summer. Insufficient light can easily make the buds fall off, the flowers become smaller and the colors darken.

2. Too dry and too wet will affect flowering. When the summer flowering season is prosperous, water 1 ~ 2 times a day according to the temperature and the dry and wet conditions of the basin soil, but thoroughly dry it to prevent the roots from rotting due to high temperature and accumulated water.

3. Change pots every year and use rotten bean cakes and poultry manure as base fertilizer. In the future, compound fertilizer with good absorption and quick effect should be applied, and 0.2% potassium dihydrogen phosphate should be sprayed on the leaves every 7 ~ 10 days to promote green leaves to sprout more.

4. Fusang is not cold-tolerant, and whether it can survive the winter safely is the key. The temperature should be kept at 12 ~ 15℃ in winter, and it is easy to freeze to death below 5℃. However, it should be noted that the temperature cannot exceed 20℃. If the temperature is too high, branches and leaves will grow in vain, affecting dormancy, and flowers will not bloom in the coming year. The relative humidity of basin soil should be kept at 30% in winter, and a lot of watering is not allowed. Generally, fertilization is not needed in winter, only a small amount of liquid fertilizer is needed.

5, pruning should be carried out in spring, leaving thick branches to ensure concentrated nutrition and more lush flowers.

Extended data:

Mulberry leaf peony reproduction method:

Commonly used cutting propagation, from early spring to late autumn, can be inserted at any time. The survival rate is the highest in rainy season, and it can only be carried out in greenhouse in winter. The annual semi-lignified cuttings are the best, and the length is about 10 cm. Cut off the lower leaves and leave the upper leaves. The incision should be flat. Put them in the sand bed and spray water every day to keep the air humidity high. Three weeks after transplanting, it takes root, grows for 45 days, and then goes to the pot.

Sexual reproduction can be carried out with seeds. However, due to the particularity of flower structure, especially indoor cultivation, the seed setting rate of natural pollination is almost zero, and artificial pollination is needed. The seed setting rate of artificial pollination is 2-5%. Seeds are difficult to germinate. Because the seed coat is thick and hard, seeds are not easy to germinate. After soaking seeds at 20℃-25℃ and sufficient oxygen, it takes about 30 days to germinate.
