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 needs to bloom in winter, and the flowering period or after flowering coincides with the growth period of new shoots. In order to control new shoots, especially trees with axillary pure flower buds, it is usually not advisable to prune them 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, generally pruning in April; Camellia grows late and is usually pruned in May. 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, these flowers and trees are mostly deciduous, all of which differentiate into buds on the new shoots of that year and then bloom in summer and autumn.
Because there is an obvious dormancy period in winter, you can prune it calmly in winter, as long as you avoid frozen 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, they are combined with plastic surgery, such as brocade, crape myrtle and hibiscus flowers. In addition, flowers and trees have some special circumstances to pay attention to.
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, and from the point of view of flower bud differentiation, they should be pruned in the dormant period. Considering its strong habit, easy flowering and abundant sap, it is obviously not suitable for pruning in the growing period, and it is best to prune in the late dormant period, that is, near early spring. Magnolia grandiflora and citrus, which differentiated in winter and spring, differentiated later, which was 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 can be divided into summer and autumn, they are pure flower buds, and they should be pruned during the growing period. However, because of their strong habits, they are easy to bloom and reduce "gummosis", so they should be pruned in winter, preferably near early spring.
Osmanthus fragrans was differentiated that year. Because the flowering period is special, the pruning time becomes "after flowering".
Many differentiated flowers and trees have to 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 growth of the next new shoot, but the pruning amount is very small.
