Which month is the best time for pruning and greening?

When sprouting in spring, you can remove the extra buds by hand, and the buds will sprout at the cut of the branches. After removal, the main branches will be weak and the branches will be staggered. In short, before lignification, all the branches and buds below the fixed stem should be removed, and the useless buds above the fixed stem should also be removed.

Short cutting of branches or trunks of seedlings should be carried out according to the needs of tree shape and seedling growth and development. Cut off pests and diseases, decaying branches, competing branches, over-dense branches and sprouting branches, the incision must be smooth and not split, and the incision of over-thick branches must be smeared.

For trees with abnormal or irregular crown, the main branches or side branches that grow too vigorously on one side can be cut off, or the strong main branches can be cut off and replaced with outward side branches.

Greening and cold protection measures:

1. Irrigation with frozen water: In late autumn, trees should be irrigated with frozen water once before the land freezes. The time to pour ice water is after the first frost and before the light snow.

2. Covering the soil: Before the land is frozen in the middle and late June (5438+065438+ 10), the shrubs with soft branches and short trees will be submerged and covered with soil. Or cover with a layer of dry leaves first, and then cover with 40-50 cm of fine sand to prevent peeling.

3. Roots cultivation: After irrigation with frozen water, the roots of trees should be cultivated with a weir with a diameter of 80 ~ 100 cm and a height of 30 ~ 50 cm to prevent frostbite.

4. Spraying white: Spraying white with lime sulfur powder on trees can reduce the risk of sudden temperature difference and kill some overwintering pests and diseases.
