When is the most suitable time to prune plant branches? Which potted plants should not be pruned in September?

In the blink of an eye, more than half of the year has passed, and from summer to autumn, the weather is getting cooler and cooler. Many flower enthusiasts begin a series of operations such as repotting and pruning at this time. However, during the process, attention should be paid: some plants that bloom in autumn and winter or bloom in spring and summer have already begun flower bud differentiation now. If you cut them with one snip at this time, there will be no flowers blooming afterward. The following summarizes several plants that should not be pruned carelessly in autumn.

Hydrangea

Hydrangea, also known as eight-immortal flower and purple sun flower, is also divided at the time of purchase into new-wood blooming varieties and old-wood blooming varieties. The pruning time for new-wood blooming varieties can be a bit more flexible, but if it is an old-wood blooming variety, you need to be more cautious, because August is exactly the time when old wood develops flower buds.

Pruning method: after August, pruning is not recommended. At this time, it is recommended to only prune detailed parts such as thin, weak, diseased and dead branches. Do not touch the robust old branches again. Because if you cut too severely, it will affect next year's flowers.

Chrysanthemum

Chrysanthemum, as one of China's traditional famous flowers, has diverse varieties and is also a must-choose flower in autumn. At this time, if you have been growing chrysanthemums all along, do not pinch the tops now, because they are already developing flower buds. If you forcibly pinch the tops now, the branches will probably find it hard to bloom again, because after pinching, the new branches need a relatively long time to recover their bud-producing function.

Pruning method: it is recommended to pinch the heart and top chrysanthemums in summer. This can, first, control height, and second, promote branching and sprouting. At this time, it is only recommended to cut off overly dense branches and diseased or pest-infested branches, and wait for new buds to sprout.

Daphne

Daphne is considered one of the few flowers that bloom in winter. Its flowers are small and exquisite, usually white or pale yellow, with petals arranged tightly and yellow stamens in the center. As long as one or two daphne flowers open, the whole room is filled with fragrance. In September, it has already begun to develop flower buds. If you severely cut off the well-developed buds now, you will definitely not see flowers this winter.

Pruning method: do not prune carelessly. The more you fiddle with it, the harder it is for it to develop flower buds. So whether you are a flower enthusiast in the north or the south, if you want to prune, do it before flower bud differentiation. After differentiation, do not use scissors to prune severely again.
