Reasonable pruning of potted flowers can make the branches distribute reasonably, save nutrients and regulate growth, so that potted flowers will look graceful and bear fruit. Pruning after germination is not only a waste of nutrients, but also difficult to shape. Therefore, pruning before germination of potted flowers in spring is particularly important. Before pruning, we should fully understand the growth characteristics and flowering parts of potted flowers. Pruning is generally divided into four types: heavy pruning, medium pruning, light pruning and coring. However, potted flowers that bloom in early spring, such as Yingchun, Plum Blossom and Rhododendron, should not be pruned before germination in early spring, but should be gently pruned one or two weeks after flowering to promote the germination of new buds. One is potted flowers blooming on annual branches, such as roses, jasmine, gardenia, hibiscus and crape myrtle. , was cut again and again. Let it grow new branches and grow stronger plants again. Bloom and bear fruit. Pruning knives or scissors should be sharp, so that the incision can be smooth and prevent the branches from breaking. To prevent the blade from rotting, the blade can be waxed. When pruning, we should pay attention to the selection of bud eyes that grow outward, so as to help the branches spread evenly, make the plants look beautiful and facilitate ventilation and light transmission. Second, the middle cut is used for potted flowers that need proper pruning to bloom well, such as wintersweet, pomegranate and kumquat. You can cut it in the middle. Pay equal attention to thinning and mowing. For the annual branches that have blossomed, leave 2~3 buds on the stems and cut them short, so as to promote the germination of the lateral branches and remove the over branches, cross branches and diseased branches. Third, light cut light cut for the potted flowers blooming on the biennial branches, light cut. Such as camellia, gardenia, peach blossom, Milan, white orchid and so on. Just cut off the redundant side branches, diseased branches and tips. When pruning, the main branches are thick and can be artificially shaped. According to personal hobbies and the actual situation of plant growth, it can be trimmed into umbrella shape, pagoda shape and so on. Fourth, pick a heart for those herbal potted flowers, such as violets, daisies, snapdragons, marigolds, black hearts and so on. It is necessary to pick the heart and head many times to make them have more lateral buds, the plants are short, strong and beautiful, and the branches and leaves are lush, so as to increase the number of flowers and prolong the flowering time. After the flowers wither, we should cut off the residual flowers in time to make the remaining bloom blossom more vigorously.
