Cultivation methods and precautions for mulberry leaf peonies

How to cultivate mulberry leaf peony:

1. Select soil and change pots: The soil for mulberry leaf peony potting should be loose and fertile sandy loam. Before moving outdoors in early spring every year, Repotting should be carried out. There are three things to do when changing the pot. First, replace it with new culture soil. Second, cut off some of the overly dense curly fibrous roots. Third, apply enough base fertilizer and a little phosphorus fertilizer on the bottom of the pot.

2. Pruning: In order to maintain the beautiful shape of the tree and the large number of flowers, mulberry peony can be pruned before and after leaving the house in early spring, except for the base of each branch. Leave only 2 to 3 buds, and cut off all the upper parts. Pruning can promote the growth of new branches, which will make them grow more vigorously and the plant shape will also be beautiful. After pruning, due to the reduced consumption of the above-ground parts, water and fertilizer should be appropriately controlled.

3. Out-of-house management: Mulberry peony is a positive tree species. It should be moved outdoors and placed in a sunny place in early May. This is also the growing season of mulberry peony. It is necessary to strengthen fertilizer, water, soil loosening, and pulling. Grass management work.

Apply thin liquid fertilizer every 7 to 10 days. Watering should depend on the dryness and wetness of the pot soil. Too dry or too wet will affect flowering. Care must be taken in post-autumn management, and attention should be paid to fertilizing less in the later period to avoid losing the autumn shoots. Autumn shoots have tender tissues and weak cold resistance, and will suffer frost damage in cold weather.

4. Enter the house in time: Mulberry-leaf peonies are not frost-resistant and must be moved indoors to keep warm after frost and before the beginning of winter. The overwintering temperature is required to be no lower than 5°C to avoid freezing damage, and no higher than 15°C to avoid affecting dormancy. If the dormancy is not good, the growth and flowering will not be prosperous the next year.

Any south-facing furniture house with good thermal insulation conditions can survive the winter. When the weather is cold, it can be covered with paper or plastic film to keep warm. When moving indoors for the first time, open the windows for ventilation every day during the day, pay attention to the changes in dryness and moisture of the pot soil, and water appropriately. In the coldest days, watering can prevent frost damage, but fertilization should be stopped.

Notes on breeding mulberry-leaf peonies:

1. Because mulberry-leaf peonies are masculine flowers, they should be placed in a place with long sunshine so that they can fully receive sunlight. In summer, It can be given full light. Insufficient light will easily cause the flower buds to fall off, the flowers to become smaller and the color to be dim.

2. Excessive dryness and excessive moisture will affect flowering. During the peak flowering period in summer, water 1 to 2 times a day depending on the temperature and the dryness and moisture of the pot soil, but it must be done dry and thoroughly. Prevent root rot due to high temperature and water accumulation.

3. Change pots every year, use decomposed bean cakes and poultry manure as base fertilizer, and then apply compound fertilizers that are well absorbed and have quick effects. Spray 0.2% on the leaves every 7 to 10 days. of potassium dihydrogen phosphate to promote green leaves and more flower buds.

4. Fuso is not cold-tolerant, so whether it can survive the winter safely is the key. The temperature in winter should be kept at 12-15°C. If it is lower than 5°C, it will easily freeze to death. However, it should be noted that the temperature should not exceed 20°C. Excessive temperature will cause the branches and leaves to grow elongated, affect dormancy, and prevent flowering in the coming year. In winter, the relative humidity of pot soil should be maintained at 30%, and heavy watering is not allowed. Fertilization is generally not needed in winter, and only a small amount of liquid fertilizer is applied.

5. Prune the branches in spring, leaving thick branches to ensure concentrated nutrients and more blooming flowers.

Mulberry leaf peony propagation method:

Cutting is commonly used for propagation. It can be inserted at any time from early spring to late autumn. The survival rate is the highest in the rainy season, and only in winter. Can be done in a greenhouse. The best cuttings are annual and semi-lignified ones, about 10 cm long. Cut off the lower leaves and leave the top leaves. The cuts should be flat. Insert them into a sand bed and spray water every day to maintain high air humidity. Roots will take place three weeks after transplanting, and after 45 days of growth, they can be potted.

Sexual reproduction can be carried out by seeds. However, due to the special structure of flower vessels, especially indoor cultivation, the natural pollination and fruiting rate is almost zero, and artificial pollination is required. The seed setting rate of artificial pollination is 2-5%. It is difficult for seeds to germinate. Because the seed coat is thick and hard, it is not easy for seeds to germinate. Soaking seeds in a temperature range of 20℃-25℃ with sufficient oxygen will take about 30 days to germinate.
