Ornamental branches of shrubs are generally not trimmed in winter. They can be cut again before budding in early spring and lightly cut later to encourage more sprouting branches so that the branches can fully play an ornamental role.

Foliage shrubs are often pruned according to the early spring flowering species for species that both view flowers and leaves; other species should be re-pruned in winter or early spring, and then lightly pruned in order to germinate more branches and leaves.

Be sure to pay attention:

1. Pruning shrubs on rainy days and when there is dew is likely to cause germs to hedge trimmer  invade plants through the wound with the rain. Avoid pruning.

2. The pruning of common flowering shrubs should be done as far as possible under the premise of retaining the original crown, and avoid heavy pruning.

3. For pruning older and stronger color blocks, first use pruning shears to remove some of the old and strong branches according to the established height, and then use large flat shears to flatten and trim the edges to achieve the overall effect.

4. The clumpy shrubs that have been planted for many years should renew senile branches and cultivate new branches year by year. For shrubs with main trunks that have been planted for many years, the cutting method of alternately retracting the main branches to control the canopy should be adopted every year to prevent the tree from being strong and weak.
