Pruning of flowering shrubs

Flowers and shrubs are used in large quantities and have a wide variety, which need careful maintenance. Before and after flowering, it is necessary to fertilize frequently and water more to flourish. First of all, we should observe the surrounding environment, lighting conditions, plant species, growth strength and its role in the garden, so as to be aware of it, and then trim and reshape it. Flowers bloom in spring, and flower buds (or mixed buds) are planted on biennial branches. Shrubs such as Forsythia suspensa, Prunus mume, Peach, Yingchun and Peony undergo flower bud differentiation in the summer of the previous year, and then bloom in the spring of the following year after the low temperature stage in winter. Therefore, pruning should be carried out when the leaf buds begin to swell after the flowers remain. The location of pruning varies with plant species and pure flower buds or mixed buds. Forsythia suspensa, ebony, peach, Yingchun, etc. 2 -4 full buds can be left at the base of the flower branch for short cutting. Peony can only cut off residual flowers. Flowers bloom in summer and autumn, and flower buds (or mixed buds) are planted on the branches of that year. For example, crape myrtle, hibiscus and ebony form flower buds on the sprouting branches of that year, so they should be pruned during dormancy. Two-year-old branches leave 2-3 full buds or a pair of opposite buds at the base. After pruning, some robust branches will sprout, with fewer flower branches, but larger flowers will bloom due to nutritional integrated circuits.

If some shrubs want to bloom twice in the same year, they can cut off the residual flowers and their 2-3 buds after flowering to stimulate the occurrence of secondary branches, and they can bloom twice by increasing fertilizer and water appropriately. A flowering shrub with flower buds (or mixed buds) attached to perennial branches. Such as bauhinia, begonia and so on. Although most flower buds are planted on biennial branches, perennial stems can differentiate flower buds under suitable nutritional conditions. For flowering plants in this kind of shrub, the pruning amount should be small, and the dry part of the tip of the branch can be cut off in early spring. In the growing season, in order to prevent flowering branches from being too lush and affecting flower bud differentiation, we can pick the core and concentrate nutrition on perennial branches.

A flowering shrub with flower buds (or mixed buds) attached to short flower branches. Such as Xifu Begonia, this kind of shrub has strong growth potential in the early stage, most buds occur from the base every year, and a large number of upright branches occur on its own branches. When plants enter flowering stage. Most branches form short flower branches, which bloom on them year after year. This shrub is generally not pruned, and the residual flowers can be cut off after flowering. When the growth is vigorous in summer, the growth should be properly picked to inhibit its growth, and excessive upright branches and long branches should be thinned. A flowering shrub that germinates and blooms many times a year. For example, during the dormant period of Chinese rose, the branches of the current year can be cut short or the strong branches can be retracted, and at the same time, the cross branches, disease and insect branches, combined branches, weak branches and branches with too dense cavities can be cut off. Strong shearing can be carried out in cold areas, and soil should be covered to prevent cold when necessary. Pruning can be done many times during the growth period, and it can be shortened when the new shoots are full of buds after flowering (usually the second bud-the third bud below the pedicel). The cut buds germinate quickly, sprout, form buds and then bloom, and then cut after the flowers wither, and so on.
