Fertilization method during basin changing and pruning

Loose and fertile sandy loam should be selected as potting soil, and the pots should be changed before moving out of the room in early spring and April every year. In the fertilization method of Fusarium flower, three things should be done when changing pots: first, replace with new culture soil; The second is to cut off some dense curly fibrous roots; Third, apply sufficient base fertilizer and slightly add phosphorus fertilizer to the basin bottom. In order to maintain a beautiful tree shape and a large amount of flowers, pruning and shaping can be carried out before and after leaving the house in early spring according to the characteristics of strong sprouting and tillering ability of Fuso. Except for leaving 2-3 buds at the base, the upper part of each branch shall be cut off. Pruning and repairing can promote the development of new branches, which will grow more vigorously and have a beautiful plant shape. After pruning, due to the reduction of aboveground consumption, water and fertilizer should be properly controlled

Fertilization after leaving the room

In early May, the positive tree species of Fuso mulberry should be moved outdoors and placed in a sunny place. This is also the growing season of Fuso mulberry. The management of fertilizer and water, soil loosening and grass pulling should be strengthened. Thin liquid fertilizer shall be applied every 7-10 days. Watering shall depend on the dryness and humidity of the basin soil. Excessive dryness or humidity will affect flowering. The management after autumn should be cautious, and pay attention to less fertilization in the later stage to avoid pumping autumn shoots. Autumn shoot tissue is young and tender, with weak cold resistance. It will be damaged by freezing in cold days

Fertilization after entering the house

Fusang is not resistant to frost. It must be moved indoors to keep warm after frost falls and before the beginning of winter. The overwintering temperature shall not be lower than 5 ℃ to avoid freezing damage; Not higher than 15 ℃, so as not to affect dormancy. Dormancy is not good, and the next year's growth and flowering is not prosperous. All furniture houses with good thermal insulation conditions facing south can survive the winter. When the weather is cold, they can be covered with paper or plastic film to keep warm. Open windows every day to ventilate the newly moved room, pay attention to the dry and wet changes of basin soil, and water appropriately. In the coldest days, watering can prevent freezing injury, but fertilization should be stopped
