Potted flowers have just sprouted in spring. At this time, pruning can make the branches evenly distributed, adjust the tree potential, control excessive growth and reduce nutrient consumption, thus making potted flowers graceful and vibrant, and promoting more flowers and more fruits. Pruning before germination can make flowers and trees germinate vigorously and reach an ideal tree shape; Pruning after germination not only wastes nutrients, but also is not easy to shape. Before pruning, we should fully understand the growth characteristics and flowering parts of potted flowers and prune them according to their physiological habits. Rose, pomegranate, hibiscus, jasmine, kumquat, gardenia, etc. Those that bloom on the branches of a year can be pruned again to make them branch, blossom and bear fruit. Buds of Spring Festival, Plum Blossom, Rhododendron, Peach Blossom, etc. Flowers in early spring are formed on the branches of the first year, and should not be pruned before germination in early spring, so as not to affect flowering and fruiting. Pruning should be carried out within 1 ~ 2 weeks after flowering to promote the germination of new shoots and the formation of flower branches in the coming year. Pruning should be based on the principle of leaving no outside, no inside, no straight and no horizontal. Cut off dead branches, twigs, long branches, cross branches and over-dense branches. The buds outside the incision should be kept to grow outward, and the incision should not be too close to the buds, which is easy to cause water loss and hinder germination. Flowers and trees that are easy to branch, such as winter coral, wintersweet and pomegranate, will be top-heavy if there are too few branches at the base of the plant. They can be cut short from the base of the trunk about 5 ~ 10 cm away from the basin soil, so that they can grow new branches again and develop into full crowns. Don't prune flowers and trees that are not easy to branch, such as five-needle pine, camellia, cymbidium and so on. Flowers and trees with soft branches, such as Yingchun and honeysuckle, are generally not pruned, but only the branches that are too old and too dense. Can be tied up and put on a shelf, so that the branches are evenly distributed, ventilated and transparent, and promote growth.

Leaf-viewing plants For large-scale leaf-viewing plants with large plants, if they are pruned frequently, they can promote their growth and make them robust and beautiful. For example, cutting the top can make the leaves of the plant dense, the shape of the plant symmetrical, and prevent the growth of vain; Cutting off the redundant lateral buds can make the plant tall and straight.

For smaller plants, such as cold spray, watercress green, reed moss and so on. , beautifully trimmed and lush. Therefore, it is necessary to cut off the bad branches before the new buds grow to keep the beautiful shape.

In order to reduce the excessive branches of foliage plants, it is necessary to determine a certain height, and often cut off the terminal buds of stems or branches to inhibit growth and make them dwarf or cluster. This method is completely different from the pruning principle of ordinary outdoor plants.

The so-called T-shaped standard plant shape of T-shaped plants means that leaves only grow at the top of the trunk, and other parts of the trunk (below the top) do not grow leaves, and the plants form an umbrella-shaped growth potential, like the shape of the English letter "T". For some tall woody foliage plants, pruning into a "T" shape will have a better decorative effect, and plants will look particularly tall and handsome, such as Brazilian wood and yucca.

The main purpose of "T" pruning is to straighten the trunk of plants. When the plant grows to a suitable height, it is necessary to cut off unnecessary side branches and leaves at the lower part of the trunk, leaving the branches and leaves at the top, then cut off the branches and leaves that grow too high and messy at the top, and finally trim them according to the determined height. In this way, after a period of growth, the top branches and leaves will become more and more lush, naturally forming a "T"-shaped standard plant shape.

In short, the height of the T-shaped trunk should be determined before pruning.

Qiao Muhua has strong branching ability. If they are allowed to grow at will, their appearance will be affected, such as plum blossom, peach blossom, Prynne, cherry blossom, bamboo peach and rubber tree. Therefore, after the survival of trees and flowers by cutting or grafting, we should first cultivate the thick trunk, cut off all the sprouting lateral branches below 30 ~ 50 cm, and then cut off the top of the trunk two years later to prevent it from growing into a single stem, and the height of the top should not exceed 80 cm. After cutting the top, the nutrients absorbed by the root system will be concentrated near the incision, which will stimulate the axillary buds to germinate and produce side branches. At this time, we should choose three evenly distributed lateral branches with different growth directions as primary lateral branches, and cut off the redundant lateral branches from the base.

When the lateral main branches are about 80 cm long, it is best to cut them short, and the remaining branches are about 60 cm long, so that secondary lateral branches can germinate, or three branches can be kept and redundant lateral branches can be sparse, thus forming a basic tree with three branches and nine tops. In the future, these nine secondary lateral branch techniques will be shortened, so that they can continue to germinate small lateral branches and form a complete crown, while retaining some branchlets in the tree cavity to increase the flowering position.

Flowers, shrubs and shrubs have no trunk, and branches are clustered from the ground. In the first few years after planting, it can grow naturally. When the clumps are too dense, the main branches in the clumps will be sparse by about half from the base, otherwise it will not bloom normally due to unfavorable ventilation and light transmission. Such as roses, forsythia, elm leaves, winter jasmine, cloves and so on.

Chimonanthus praecox, hibiscus, Chinese rose, cinnamon, Milan and Michelia are all shrub flowers. They are characterized by weak rhizosphere germination rate and clustered branches concentrated in the root neck. We can use this feature to make them into small trees, thus improving their ornamental value.

In spring, we should first remove the redundant branches and keep only one main branch, so that the axillary buds on the main branch and the adventitious buds on the root neck can grow many side branches. At this time, only four lateral branches at the top of the main branch are kept, and all the lower lateral branches are cut off, and then secondary lateral branches can grow on these four lateral branches. Then some side branches will sprout at the main branch and the base of the main branch, which should be cut off in time. In this way, a shrub is changed into the shape of a small tree, and the flower branches are pulled out from the side branches.

Beat binding Beat binding modeling is suitable for potted flowers with soft branches that cannot stand upright, such as Tanchun, Yingchun, Ivy, Guanglingxiao and Xianrenzhi. Each tree can only keep 1 main branch, and at the same time keep the trunk with the length of 10 cm. After the lateral branches germinate, they are evenly drawn or tied to the beat. For succulent plants such as fairy fingers, it is necessary to help the knotted succulent stems droop naturally after crossing the beat.

When shooting, one side branch should be left on the main branch every 6 ~ 10 cm, and the redundant side buds should be removed as soon as possible. Too many and too dense lateral branches will interweave with each other and lose their layers. When pulling, they should try to be sparse and dense. After the plants grow on the beat for many years, the branches will become thicker year by year, although they will become thinner year by year. When the bracket can't bear it, it is necessary to change the basin, change the soil and re-bind it with a larger bracket.

In order to restrain the growth of flowers and make them grow into small and exquisite plant shapes, the trunk can be pinched into an "S" shape when it is young. Such as peach blossom, straight smile, plum blossom, bougainvillea and so on. When bending the trunk, insert a thick stick in the pot soil, then twist the branches and tie them to the stick in sections. For their side branches and the side branches of poinsettia, bend them by pulling ropes. Stop watering from the day before bending, and wait until the branches become soft before watering to facilitate bending. If you catch a branch when you bend, you can wrap the broken parts with plastic strips and let them heal slowly.

The characteristics of viewing flowers and fruits are beautiful flowers, many flowers and fruits, and timely viewing. In addition to water and fertilizer management, pruning should also be used to adjust the relationship between branch growth and flower and fruit development in order to promote flowering and fruiting. First of all, we should consider the number of flowers and fruits and the area of leaves, and maintain an appropriate proportion, so as to fully carry out photosynthesis and supply enough nutrients to meet the needs of flowering and fruiting. Especially ornamental plants, we should pay more attention to leaving enough leaves.

The flowering and fruiting time of flowers and trees is different because of different varieties. Generally, when flowering in early spring, flower buds are mostly formed on the first-year branches. Therefore, in the winter dormancy period, it is not advisable to cut peaches and plum blossoms. Only the autumn shoots without flower buds can be cut off, but a plastic pruning should be done after flowering.

Flowers in full bloom that year, such as crape myrtle, oleander, rose, poinsettia, kumquat, etc. Strong pruning should be carried out in winter dormancy period to concentrate nutrition, which can promote more strong branches in the next spring. Some flowers and trees generally do not need to be pruned frequently, such as azaleas and camellias. In order to maintain the beauty and symmetry of the tree, the tops of some branches can also be cut off appropriately, but don't prune them vigorously. Vine flowers generally do not need pruning, just cut off old branches, dense branches, pest branches, blind bud branches and so on. Keep it ventilated and transparent.

There are also flowers such as hydrangea. In winter, all branches and leaves should be cut off, so that their stems can continue to sprout, promote the propagation of flower buds and make the plants neat and strong. After autumn, Zhu Dinghong can cut off all the leaves. When entering the room, it should be placed in a sunny place, and the room temperature should be kept at around 20℃, so that it can bloom before and after the Spring Festival. Generally, carnation and other grass flowers, after flowering in June, cut off the aboveground parts and open another crop in autumn.
