Methods of propagating Salix babylonica
Today's focus is on the introduction of the propagation of Salix babylonica, a method of propagating this plant. If there are any mistakes, please feel free to correct them!
Propagation of Salix babylonica usually adopts the cutting method, which is very easy to survive. Cuttings can be taken from any part of the branch, and propagation by cutting is possible in spring, summer, and autumn. Cut branches 8 to 10 centimeters long, leaving 2 to 3 leaves, using fine sand as the cutting medium, and cover with a shading net. The best temperature for root growth is between 20°C and 25°C. During the day after planting, it is necessary to spray water frequently to maintain air humidity. Roots usually begin to grow in about 15 days, and the plants can be transplanted after one month. The roots of seedlings propagated in sand beds are relatively fragile and easily dehydrate, so once the seedlings are lifted, they should be planted immediately.
Seedling care Before potting young seedlings, they should be planted in the ground for a period of time to allow the roots to grow better and promote the dense growth of the aboveground branches and leaves in a short time.
Seedling transplanting can be done at any time of the year. In winter, plastic film should be added to prevent frost and increase the survival rate. The planting method involves making ridges that are 1 meter wide and at least 30 centimeters high, digging holes in two rows, with a spacing of 25 to 30 centimeters between plants, and planting 3 plants closely together in each hole. It is best to place some fire soil ash at the bottom of the hole, which helps the young seedlings grow new roots quickly and provides more soil when lifting seedlings for potting. After transplanting, if the seedlings have not yet sprouted new leaves, it is important to keep the soil moist.
Cultivation management For seedlings planted in spring and summer, new leaves can grow in about 20 days. At this time, fertilization can begin, once every 15 days, mainly using nitrogen fertilizer. Fertilization should stop after the Minor Snow festival, and watering should be gradually reduced to make the soil slightly dry, which is beneficial for overwintering.
Seedlings planted from May to July can be successively lifted and potted after the following April. If used for landscaping, they need to be cultivated for another year. The specific operation of lifting seedlings involves digging up the 3 combined plants at the same time, trying not to loosen the roots, removing the lower leaves of the stems after digging, then tying the 3 plants into 1 with plastic tape at the upper part of the stem, and potting them. After potting, pruning and shaping should be carried out according to the intended use, generally cutting off half or one-third of the top leaves.
Although Salix babylonica has the characteristic of heat resistance, because most of the potted plants are used for indoor display, they should be placed in the shade after potting. This is conducive to the recovery and growth of the tree body and allows it to gradually adapt to the change of environment from the field to the indoors. In a short period after potting, the leaves may show signs of wilt and droop. During this period, no fertilization should be applied; after watering thoroughly once, keep the potting soil moist, but do not overwater. The plants can recover after a week. Then, fertilization can be carried out as described previously. Before moving the plants indoors, apply 20 grams of compound fertilizer to the edge of the pot. Generally, it takes about 2 months of care and management from potting to moving indoors.
