How to propagate Campsis radicans? Introduction to common propagation methods

Campsis radicans (see details) is also known as American trumpet vine or Du Lingxiao. It is a deciduous shrub often cultivated in China as a courtyard ornamental plant, and is also cultivated in parks throughout Henan. Campsis radicans can be propagated by cuttings, layering and division. Here is a brief introduction to these three propagation methods and points to note.

I. Propagation by cuttings

For Campsis radicans cuttings, spring cuttings of hardwood branches with aerial roots are mostly chosen, and layering is done in summer. Division mostly uses root suckers. Seedlings from seed propagation should be shaded. Winter pruning is needed every year, thinning out overly dry and dead branches. Applying fertilizer and water before flowering can promote lush leaves and abundant flowers. It can be done in spring or the rainy season; in the Beijing area, July to August is suitable. Cut relatively firm and sturdy branches, each 10-16cm long, and insert them into a sand bed, covering the top with glass to maintain sufficient temperature and humidity. Generally at a temperature of 23-28°C, roots can form 20 days after insertion, and by the next spring they can be moved to the field, with a row spacing of 60cm and a plant spacing of 30-40cm. In warm southern regions, the new shoots of the previous year can be cut in spring and inserted directly at the edge of the field, where they will take root and survive.

II. Propagation by layering

For Campsis radicans, in July, pull sturdy vines to the ground surface, bury them section by section with soil mounds, leaving the buds exposed, and keep the soil moist. Roots will form in about 50 days, and after rooting, cut them off and transplant. In the south, layering can also be done in spring.

III. Propagation by division

This is best done in early spring, that is, digging up the small seedlings that grow from root buds near the mother plant and planting them.

Campsis radicans has abundant, brilliantly colored flowers, smooth leaf surfaces, and dense white soft hairs along the midvein on the underside. It is highly adaptable and an ideal landscaping plant. So how do you propagate Campsis radicans? Let's find out together.

Campsis radicans can be propagated by sowing, cuttings, layering and division. Let's briefly learn about these methods.

II. Care tips for Campsis radicans

For early-stage management of Campsis radicans, pay attention to watering; later-stage management can be more rough-and-ready. When the plant grows to a certain size, set up support poles. Before sprouting each year, appropriate thinning can be done, removing dead branches and overly dense branches, so that the tree shape is reasonable and growth is favored. Before flowering, apply some compound fertilizer and compost, and carry out appropriate irrigation, so that the plant grows vigorously and blooms densely.

For potted Campsis radicans, it is best to choose plants over 5 years old, keep the main trunk and cut it back to 30-40cm, while also trimming the roots and retaining the main root system. After potting, let it regrow new branches. Of the new shoots that emerge, keep only the upper 3-5 and cut off all the lower ones, shaping it into an umbrella form, and control water and fertilizer; it can take shape after one year. Set up a trellis and let it climb freely. After buds appear in the summer of the following year, thin the flowers in time and apply one liquid fertilizer, and the flowers will be large and brightly colored. In winter, place it indoors above freezing to overwinter, strictly control watering, and prune before sprouting in early spring.
