Pruning in a broad sense refers to the attitude of pruning trees, and "cutting" refers to cutting off branches.

Through shaping and pruning, not only can the plant shape be neat, layered, patchwork, moderate height and beautiful shape, but also the ornamental value can be improved; Moreover, cutting unnecessary branches in time can save nutrients, adjust tree vigor and improve light transmission conditions, thus regulating the growth and development of flowers and trees and promoting the robust growth and fruiting of flowers.

This paper expounds the contents of flower and tree pruning, including pruning, coring, leaf picking, bud stripping, fruit thinning, bud wiping, shoot cutting and root cutting.

After pruning, foliage plants are beneficial to sprout new branches and produce more leaves, thus enhancing the ornamental effect.

If you don't do plastic pruning for a long time, first, the branches sprouting at the base of flowers and trees grow into clusters, which leads to scattered nutrients and unbalanced branches and leaves. It is often easy to have lush branches and leaves at the top and "bare legs" at the bottom, which is very ugly; 2. Let it grow naturally, not only the branches grow disorderly, but also some indoor flowers and trees grow taller and taller, which affects indoor lighting and makes the flowering part move up, so the number of flowers is greatly reduced, which greatly affects the ornamental effect.

Therefore, plastic pruning is an essential daily management measure for cultivating flowers.

The flower proverb "seven points depend on management, three points depend on cutting" is scientific and also an important flower cultivation experience.

The best time for flower pruning

There are many kinds of flowers, and different kinds of flowers and trees have different pruning time.

When pruning flowers and trees with ornamental flowers as the main purpose, we should master the flowering habits of different flowers and trees.

Places in bloom in spring, such as plum blossom, peach blossom and winter jasmine. Their flower buds are formed on the branches in the first year, so they are not suitable for pruning in winter. If you prune before germination in early spring, the flower branches will be cut off.

Pruning should be carried out within 1-2 weeks after flowering, which can not only promote the germination of new shoots, but also form flower branches in the next year.

If you wait until autumn and winter pruning, the branches that have formed flower buds in summer will be damaged, which will affect the flowering of the next year.

All the flowers and trees that bloomed on the branches of that year, such as rose, hibiscus, poinsettia, hibiscus, kumquat, bergamot, etc. Pruning should be done in winter dormancy to promote more buds, more flowers and more fruits.

Vine flowers generally do not need pruning, just cut off the old and dense branches.

Flowers and trees mainly used for leaf viewing can also be pruned during dormancy.

How to prune flowers during their growing period

1. Fruit cracking: In order to prevent branches from overgrowth or forming certain artistic shapes, fruit cracking treatment is often carried out in early spring when tender buds are slightly sprouted.

The extensive technique is to break branches by hand; The ingenious technique is to cut with a knife first, then carefully bend the branches and smear mud at the incision to prevent the wound from evaporating too much water.

2. Bud removal (that is, bud wiping): Usually, lateral buds or redundant buds sprouted on branches are removed.

3. Core-taking: remove the top of the new shoot by 2-5 cm to inhibit the growth of the new shoot and transfer nutrients to reproductive growth.

When the bud on the upper part of the new branch germinates the second bud, when it grows a few leaves, it can be cored again.

4. Twist: Twist the new branch, but don't break it from the mother branch. This method is mostly used when the new branch grows too long.

The purpose of twisting the tip is to prevent nutrients and water from being transported to the growing point, weaken the growth potential of branches, and facilitate the formation of flower branches.

At the same time, because of the small stimulation, it will not produce secondary cusp.

3. Bending branches (bending branches, binding branches and tying branches): that is, measures such as bending, binding or erecting branches or new branches are taken to control the germination of branches or buds on them, and can also be used to shape trees into various artistic shapes.

4. Leaf removal: remove too many leaves appropriately to improve ventilation and light transmission conditions.

5. Picking buds: In order to obtain large and colorful flowers, the growth of main buds can be promoted by picking off side buds.

6. Fruit picking: Sometimes in order to enrich the growth of branches and avoid excessive nutrient consumption, young fruits are often picked; Sometimes in order to obtain large and good quality fruits, appropriate fruit thinning is carried out; Sometimes, in order to keep the flowers blooming, fruits are often picked.

Four methods of pruning flowers during dormancy

1, relay: relay trunk or thick main branch and backbone branch.

When cutting off thick side branches, first saw 1/3-2/5 from bottom to top under the base of thick branches, and then saw it from top to bottom to avoid splitting.

Finally, flatten the wound with a sharp knife and apply a protective agent to prevent pests or water evaporation.

2. Thinning: Prune from the base without retaining the buds at the base.

Thinning can make the distribution of branches reasonable and symmetrical, improve the ventilation and light transmission conditions in the crown room, and reduce the occurrence of pests and diseases.

The objects of thinning branches are mainly pests and diseases, disabled branches, dense branches with cavities, dead branches, combined branches, excessively dense cross branches, weakly drooping branches and interfering branches.

Generally speaking, thinning should reduce the number of branches and buds and prevent excessive new shoots from consuming nutrients, so it is beneficial to flower bud differentiation and flowering and fruiting.

3. Pruning: Prune a part of the annual branches and keep a few buds at the base to stimulate the lateral buds below the pruning opening to sprout new buds, increase the number of branches and promote more leaves and flowers.

At the same time, it can shorten the distance between branches and roots, which is beneficial to the transportation of nutrients.

Pruning can also change the position of top advantage, control the size of crown and the length of branches.

4. Shrinking: it is pruning of perennial branches, which is mostly used to update branches or backbone branches, or to tighten the crown.

When pulling away, thick branches and upright branches should be left under the incision, and the wound should be small, so that the branches under the incision can flourish or stimulate the germination of marrow buds.

The main thing is to make the branches centripetal again, which is more robust.
