When the plant has finished flowering, you should consider pruning it.
In many cases, pruning is merely a cosmetic procedure. For instance, you can prune the bushes into the shape you want by trimming some leaves and stems.
If the plants are left intact, they may lose their initial shape. However, if you strive for a natural appeal or even artistic chaos, we recommend leaving your plants alone.
Pruning has other benefits apart from aesthetic pleasure. Some plants may be short-lived if unpruned. Moreover, the following flowering and fruiting may be unsuccessful.
Please note that pruning more than 30% of the foliage at once will provoke shock and stress.
