Pruning method of Tripterygium

Tapestry Begonia blossoms for a long time, large and colorful, and is welcomed by flower lovers. Today we would like to introduce the pruning method of Tripterygium. If you are interested, let's have a look at it.

Pruning method of Tripterygium

Spring pruning: pruning is best when the tree has not yet germinated in early spring, and the pruning methods are mainly short cutting and branch thinning.

1. Newly planted plants: according to the principle of keeping the good and eliminating the bad, 3 to 5 strong branches are generally selected to cut off too many weak twigs, disease and insect pests and curved branches from the base, so as to promote the germination and growth of new branches from the rhizosphere in the coming year, increase the number of branches in the clump, and pay attention to not leaving stakes when cutting. For the selected strong branches, usually the strong branches are cut lightly, the weak branches are heavily cut, and the outward buds are left at the cut in order to expand the scope of the clump, and at the same time, the cluster is hollow, which is conducive to ventilation and light, and more flower buds are formed. In places where the conditions of fertilizer and water are good, they should be cut lightly and long, and where conditions of fertilizer and water are poor, they should be cut again and stay short.

2. The plants after planting:

The ideal shrub type should keep the state of high inside and low outside, sparse and dense inside, which can not only make the branches receive sunlight evenly, but also increase the permeability of shrubs, which is more conducive to the healthy growth of plants. The specific pruning methods are as follows:

The main results are as follows: (1) cut off the disease and insect branches, cross branches, over-dense branches, overlapping branches and introverted branches from the base. Choose 5 to 8 branches with suitable direction and thickness, and the cutting height should be the same at the base.

(2) since the flowering branches of 3-5-year-old begonia are the most, the flowering branches should be renewed year by year to keep the plants in full bloom, and the floral branches should be renewed year by year, generally 2 to 3 branches per year, and the excess new branches and old flowering branches can be removed.

(3) as the flower buds of Begonia are basically born on the short branches, a few sections should be left and cut off to increase the short branches.

Post-flowering pruning

In order to maintain the tree shape and make the overall effect beautiful, it needs to be pruned properly after flowering. Remove the crowded branches on the plant and the protruding branches on the crown outline two weeks after flowering. Properly truncate the long branches, leave 3 to 4 buds from the base, and cut off the rest, which is beneficial to increase the number of short branches that form flower buds. The fruit after anthesis should be removed as soon as possible to avoid nutrient loss and affect the formation of flower buds in the following year.

Matters needing attention

1. In order to control the plant height, the truncation of flower branches should be light and should be carried out year by year, so as to avoid the influence of heavy truncation on the number of flowers in spring.

two。 The number of branches should be determined according to the size of the space. When planting a single plant, you can leave more branches; if you plant in rows or in pieces, if the space is small, you can leave fewer branches.

3. When pruning after anthesis, the branches with leaves are subtracted, the photosynthetic area is reduced, and the growth of the plant is inhibited, so the pruning should be light.
