Pruning should choose the right time and master the correct pruning method. Generally, pruning can be carried out in dormancy and growth period, but the specific time to master it depends on their habits, cold tolerance and pruning purpose.
Generally, flowers that bloom first and then grow leaves in early spring, such as plum blossom and spring jasmine, have buds on biennial branches, so they must be pruned after flowering. If pruned before germination in early spring, the flower branches will be cut off, resulting in non-flowering.
Therefore, pruning should be carried out within 1-2 weeks after flowering, but at this time, flowers and trees have begun to grow and the flow is relatively strong, so the pruning amount should not be too large.
Flowers and trees that bloom in summer and autumn, such as crape myrtle, rose and jasmine. All have their flower buds on the branches of that year, which can be pruned during the dormant period before germination.
Leaf-watching flowers can also sleep.
When pruning during dormancy, those with strong cold tolerance can be pruned in late autumn and early winter, and should not be pruned too early, so as not to induce autumn shoots, which is not conducive to flowering and fruiting in the coming year and keeping out the cold and freezing.
People who are afraid of poor things should do it before the sap begins to flow out in early spring and germinate.
In addition, the purpose of pruning or pruning flowers and trees is to renew, so when forced pruning is needed, it is suitable for dormancy.
During the growth period of flowers, pruning is mostly for ventilation and light transmission, pest control, long white branches or nutrition adjustment, so that the flower posture is more elegant, dense and robust, and the pruning degree should generally be light.
Also pay attention to the outside of the cut bud, so that the branches extend outward and the incision becomes an inclined plane, and the bud should stay on the other side of the incision.
The top of the cut slope should be slightly higher than the remaining bud 1-2 mm, not too high or too low.
Pruning and coring: Pruning and coring are the work of removing the top of growing branches.
After the branches become hard, you need to cut them slightly with scissors to make them tender. If they are tender, you can pick the core with your fingers.
The purpose of pre-pumping and coring is to inhibit the harmonious growth to a higher height, which is beneficial to nutrient accumulation, enrich branching tissues, promote the germination of lateral branches, increase the number of branches and flowers, or dwarf the plants, make the plant shape perfect and blossom neatly. For example, a chrysanthemum can bloom more than 3,000 flowers, which is the result of repeated enucleation. In addition, enucleation can also inhibit growth and delay flowering.
Bud wiping: Bud wiping is to wipe off axillary buds, twigs or buds of flowers. The purpose is to concentrate nutrients, so that the trunk is tall and straight, the flowers are big and gorgeous, and the fruits are rich and full.
Thinning branches: in order to adjust the posture of the tree, it is beneficial to ventilation and light transmission, such as dead branches, pests and diseases, slender branches, parallel branches, clustered branches and dense branches. It is usually cut off. During thinning, the stubble should not be too long and should not be cut to the next branch. The upper incision should be cut at an oblique angle of 45 degrees from the branch point, and the incision should be smooth and flowers and trees with weak germination ability, such as Magnolia grandiflora and White Finland. , should be thinned.
Root cutting: Root cutting is mostly carried out when transplanting and changing pots (turning pots). For example, when transplanting seedlings, the excessively long taproots should be cut short to promote the growth of lateral roots, while when flowers put pots or change pots, moderate root cutting can inhibit the excessive growth of branches and leaves and promote the formation of buds.
Rooting is usually carried out during dormancy, but when plants grow excessively, it can also be carried out during growth.
Vertical support: also called "tying", potted flowers climb vines, such as creeping hydrangea, Lingxiao, wisteria and so on. , should be tied with thin bamboo poles, reed poles or thick lead wires, and vines should be tied with warps to make them climb and grow and increase the ornamental effect.
Flowers and plants modeling
There are various forms of plastic surgery, such as single stem (such as single chrysanthemum, single stem dahlia, etc. ), more dry (such as begonia, pomegranate, peach blossom, plum blossom, etc.). ), overgrown (such as brown bamboo, southern bamboo, anchovies, etc. ), and drooping (such as cliff chrysanthemum, ivy, etc.). In short, according to needs and hobbies, after artistic processing and careful consideration.
