Key points: the so-called tree month is almost always grafted with roses, and the rootstocks used are generally roses and shanhuangxiang. Roses are generally grafted with lollipop roses or old bonsai, and big trees are generally grafted with mountain yellow incense. Tree Moon is very popular. A tree can be grafted with roses of several colors, which will be colorful and beautiful after flowering. It is widely used in urban greening. Of course, it is also a good choice as a potted plant. One or two trees are quite suitable for the courtyard.
How to prune trees and the moon? Tree pruning mainly adopts the modeling characteristics of 3 stems and 6 branches or 6 stems 12 branches. After molding, it looks like a pagoda, which is very beautiful.
1, wipe the bud
The maintenance in the later period after grafting is mainly to wipe off all new buds on the rootstock and all budding buds at the root. What we need is grafted roses, not rootstock branches, so removing budding buds can concentrate nutrition on grafted roses. The job of wiping buds is long-term, just needed and can't be lazy. Laziness easily leads to the waste of rootstock nutrition and the premature aging of grafted branches.
2, cultivating main grafting branches
As I said just now, we mainly adopt the modeling methods of 3 stems and 6 branches and 6 stems 12 branches. Of course, there are other modeling features. We graft the branches according to the size of the rootstock, arrange the grafting according to the spacing, make up the grafting in time if the grafting fails, and maintain the trunk after the grafting survives.
When the new main branch of the grafted rose branch grows to about 4 cm, it is cut short to achieve the purpose of 3-6,6-0/2. The simple thing is to increase the number of branches. When the secondary branches grow to about 4 cm, cut them off again. In the later stage, the primary and secondary branches are mainly cultivated to thicken the branches, and the tertiary branches are responsible for flowering. Don't cultivate tertiary trunk branches, because there are too many branches and insufficient nutrition.
3. Pruning and maintenance
We mainly use 6 stems with 12 branches for greening, which is of course related to the size of rootstocks. We mainly maintain the first and second branches, and then prune them frequently. Branches should not be too dense, so trim three spaces to ensure the light and growth space of branches. The third branch is a flowering branch, which should be pruned in time after each flowering so as to sprout new branches and blossom. The first and second branches can be properly thinned according to the needs of the rootstock.
Finally, in addition to trimming the shape, it is also important to maintain the tree month. Nutrition and water should be supplemented regularly, and the light should be sufficient. The most important thing is to keep the roots of rhizomes strong. If there is no problem with the rootstock, it will continue to provide nutrients and water to ensure the good growth of roses, and the branches of roses should be pruned frequently to prevent diseases and insect pests and enhance the tree potential, so as to achieve the effect of perfect shape and flourishing leaves.
