How to prune Clerodendrum thomsoniae

1. Topping and pinching

Whether it is propagated by sowing or cuttings, when the height of the seedlings is over 15 cm, it is necessary to top and pinch the branches and leaves at the top of the plant. The purpose of pinching is to promote the growth of the plant's side branches and control the height of the plant.

2. Pruning branches

During the growth process of the Clerodendrum thomsoniae, it is also necessary to promptly cut off the yellowing, overgrown, and diseased branches and leaves, and trim the withered flowers after the flowering period. This can reduce excessive consumption of nutrients, promote the growth of the plant, and improve the ornamental value of the plant.

3. Comb the branches

During the maintenance of the Clerodendrum thomsoniae, if you find dense and overlapping branches, you should thin them out in time and cut off the overly dense branches to increase the light transmittance of the plant. Otherwise, it will not only be detrimental to the appreciation of the plant, but also affect its normal growth.

4. Repotting and pruning

The growth rate of Clerodendrum thomsoniae is relatively fast, and the soil in the pot generally needs to be changed every 1-2 years. During the process of repotting the plant, rotten and overgrown roots can be cut off to ensure the growth of the plant.

5. Post-cutting processing

After completing the pruning of the Clerodendrum thomsoniae, you must strengthen the management of the plants. First, disinfect the plants to prevent the incision from being infected by bacteria. During daily maintenance, you need to control the light, water, and nutrients. The most critical thing is to ensure the rapid recovery of the plants.
