When is the best time to trim ornamental flowers and trees?

Tree species of flowers and trees: ornamental flowers (or fruits) are the main tree species of flowers and trees. The purpose of pruning is to deal with the relationship between growth and development, because growth is not only the premise of development, but also often conflicts with development.

Therefore, the maintenance and pruning of flowers and trees are usually different from plastic surgery, generally pruning more than twice a year. ① The flower buds are late-maturing flowers and trees.

Mainly represented by summer and autumn differentiation type, this kind of flowers and trees have more deciduous leaves than evergreen trees, and the flower bud differentiation time is particularly long. After the differentiation is completed, it usually takes winter to bloom, and the flowering period or after flowering coincides with the new shoot growth period. In order to control new shoots, especially tree species with axillary pure flower buds, it is usually not suitable for pruning in winter to prevent "light festival".

Their pruning time can be simply summarized as "after flowering", that is, it should be completed before the flower buds begin to differentiate, and the specific time can be determined by referring to the flowering order.

For example, Chimonanthus praecox blooms earliest and prunes earlier, usually in March; Plum blossoms take the second place, usually pruned in April; Camellia grows late and is usually pruned in May. Among them, deciduous trees can be arranged properly in winter, but be careful not to cut more.

② The flower buds are early-maturing flowers and trees.

Mainly represented by the differentiation type of that year, most of these flowers and trees are deciduous, and they all differentiate into flower buds on the new shoots of that year, and then bloom in summer and autumn.

Because there is an obvious dormant period in winter, you can prune it calmly in winter, as long as you avoid freezing days. The main purpose of pruning is to ensure that trees grow as many new branches as possible when they grow in the next spring, and by the way, it is combined with shaping, such as brocade, crape myrtle and hibiscus. In addition, there are some special situations in flowers and trees that need attention.

Nerium indicum was a differentiated tree species in that year, and there was no obvious dormancy period. From the point of view of evergreen trees, they should be pruned in the growing period, while from the point of view of flower bud differentiation, they should be pruned in the dormant period. Considering its strong habit, easy flowering and juicy tree body, it is obviously not suitable for pruning in the growth period, and it is best to prune in the late dormancy period, that is, near early spring. The differentiation time of Magnolia grandiflora and Citrus in winter and spring is relatively late, which is basically similar to the fruit maturity. Their pruning time should be carried out as soon as possible after flower bud differentiation, which can be summarized as their own "consequences"

The basic pruning of differentiated mixed buds in summer and autumn is mostly carried out after flower bud differentiation to before and after dormancy, which can be summarized as early winter or winter, such as peony, hydrangea, pomegranate and clove. Although peach blossoms are different in summer and autumn, they are pure flower buds and should be pruned in the growing period. However, due to their strong habits, they are easy to bloom. In order to reduce "gummosis", they are mostly pruned in winter, preferably near early spring.

Osmanthus fragrans was differentiated that year. Because of the special flowering period, the pruning time has become "after flowering".

Many differentiated flowers and trees sprout and bloom many times a year, so they must be pruned many times, such as roses and jasmine.

Because their flower bud differentiation is carried out with the growth of each new shoot, in order to make them bloom many times, they need to be pruned quickly after each flowering and before the next new shoot grows, but the pruning amount is very small.
