How to trim the Chinese dragon's tongue

When to prune the Chinese thorn tree

To shape the beautiful plant shape of the Clerodendrum thomsoniae, when the cuttings or sown seedlings grow to 15 cm after potting, cut the branches 10 cm away from the mouth of the pot to promote the sprouting of strong new branches.

During the growing period, the height of the branches must be strictly controlled, and attention should be paid to topping and pinching to ensure neat branches and dense flowering in the future. Half a month after pinching, apply chlormequat or dwarfing agent to control the height of the plant, so that the plant is short, leafy and has many flowers.

When repotting every spring, the above-ground branches should be pruned short to make the plant round, with more branches and flowers.

How to trim the Chinese dragon's tongue

Clerodendrum thomsoniae is a climbing evergreen shrub. In order to maintain its beautiful shape, it must be pruned frequently. Generally, when repotting in early spring in April, the plant is cut 10-15 cm above the pot mouth, and the upper part is removed to encourage the sprouting of thick new branches.

During the growth and development period, pay attention to pinching, control the height of the branches, and make the branches neat. After each flower fades, the flower stems should be cut off in time to make the plant short and full. This method of heavy pruning can not only promote lush flowering and leaves in the following year, but also avoid the trouble of setting up a support.

Processing of Cut Flower Materials of Clerodendrum thomsoniae

When using Clerodendrum thomsoniae as cut flower material, it is necessary to trim the branches that are thick and have many flowers. Only flower lovers who plant the flowers on a large scale need to pay attention to this.

The leaves of the Clerodendrum thomsoniae are dark green, the calyx is like jade, and the corolla is crimson, which is full of poetic and picturesque beauty. Potted plants decorate windowsills or balconies, with handsome shapes, bright and novel appearance.

During storage and transportation, the flowers are sensitive to ethylene. Ten days before storage and transportation, spray them with 0.4 mmol/L silver thiosulfate solution. If flowering plants that have not been sprayed with silver thiosulfate are transported in the dark for more than 1 day at a temperature of 20°C, the flowers will fall off.
