Planting pile:
Before planting Vitex negundo, all branches should be trimmed and dwarfed, and root wounds should be corrected to be smooth and burr-free, Mao Kou. Conducive to root wound repair and rapid rooting.
Fresh river sand can be used as soil for planting yellow stems, which is sterile and disease-free, loose and breathable, and well drained. Using river sand to support piles is suitable for most downhill piles except Vitex negundo.
Daily management:
In the daily management, the wet and dry state of the flower soil is used to achieve "watering thoroughly without doing it". And often spray wet Vitex negundo trunk and branches. Create a humid microclimate environment. Keep the branches for a long time.
Vitex negundo grows very rapidly after planting. After planting in spring, nutrition can be properly supplemented in autumn. Water the flower soil with the dilute solution of farm organic fertilizer and supplement the "nitrogen-based" nutrients, 2 to 3 times a month. "Phosphorus and potassium" can promote root growth. Bury a small number of holes in the flower soil every month.
Pruning and storing branches:
Vitex negundo has super ability of sprouting tillers. Erase adventitious buds frequently after planting to reduce nutrient consumption. Concentrate nutrients on branches for storage. In summer, the flowers of Vitex negundo are cut off, which consumes less nutrition. Continue to stock the branches.
The shape of Vitex negundo is mainly "keeping branches and cutting dry". When the main branch is 2/3 of the trunk size, shorten the main branch and shrink it into segments to form a first-class branch. Side branches are born on storage nodes, and secondary branches are reserved. Step by step, release three. Form a cloud-like branch. The aluminum wire is tied, and the main branches are arranged in four directions of the trunk in an orderly manner. And form a clear hierarchical structure of leaves.
