The reproduction of weeping willow is dominated by cuttings, and it can also be reproduced by seeds. Cuttings are carried out in early spring, choose fast-growing, no pests and diseases, and use cuttings for reproduction.
The reproduction of weeping willow is dominated by cuttings, and it can also be reproduced by seeds. The cuttings are carried out in early spring, and the male plants with fast growth, no pests and diseases, and graceful posture are selected as the mother plants for the cuttings, and the 2 to 3 year-old thick branches are cut and cut into 15 to 17 cm long as cuttings. The spacing between the rows of plants is 20×30cm, and the plants should be inserted straight and fully watered after insertion, and the soil should be kept moist. The survival rate is extremely high.
Weeping willow is one of the commonly used street trees. To make weeping willow grow fast and straight, you should pay attention to the following points:
1. Water and fertilizer: Plant growth requires a lot of water and fertilizer, so it should be fertilized frequently and watered more often. Generally, it can grow to about 2 meters a year.
2. Pruning: Weeping willows are not easy to control during the growth process and often grow and bend. The key to making the weeping willows straight is pruning.
1. Pruning of cuttings: The side buds of cuttings should be removed when cutting.
2. Pruning of annual seedlings: If the annual seedlings are less than 1 meter or poor in shape, they should be shortened to about 10 cm in the early spring of the following year, leaving only one main branch and cutting off all the other side branches.
When the annual seedling grows to 2 to 3 meters, all the side branches cannot be cut off, otherwise the tree will easily bend. Diseased branches or short side branches can be removed to balance the nutrient supply. In this way, although the tree has many side branches, the tree grows straight.
3. Pruning of two-year-old seedlings: For two-year-old seedlings, the lower side branches can be cut off, and the upper side branches can be cut short.
3. Hand pinching: Because the trunk of the weeping willow is soft, you can pinch it firmly in the bend, and the tree will grow straight over time.
Through the above management measures, weeping willows can generally grow into street trees 3 cm thick and 3 meters high within 3 years.
