How to Propagate Campsis
As a vine plant with both ornamental and medicinal values, Campsis is deeply favored by gardening enthusiasts for its stunning orange-red flowers. Mastering scientific propagation and transplantation methods will allow this climbing expert to showcase its unique charm on courtyard walls and pergola fences. This article systematically analyzes three propagation techniques and key transplantation points to help you easily create a waterfall-like flower display.
Three Core Propagation Methods for Campsis
Seed Propagation: New Generation Cultivation Technique
Select plump seeds from the current year's harvest and soak them in 40°C water for 24 hours to activate the embryo. The river sand substrate should be sterilized with high-temperature steam, and the seeds should be sown with a thin layer of soil (0.5cm). Build a small arch shed to maintain 85% humidity, and young seedlings can emerge from the soil within 15-20 days. Note that seeds over three years old have a germination rate of less than 30%.
Divide Propagation: Clone Technique from the Mother Plant
Select young plants from the base of the stem when repotting in spring, retaining a 15cm aerial root system. Soak in a 500x solution of carbendazim for 30 minutes before planting 3-4 plants per group. Use a mixed substrate of peat soil and perlite in a 7:3 ratio, and initial shading can increase the survival rate to 95%.
Cutting Propagation: Branch Regeneration Technique
Select semi-woody branches and cut 12-15cm cuttings, leaving 2 half-cut leaves at the top. Maintain a pH of 6.0-6.5 in the vermiculite substrate, and insert the cuttings to a depth of 8-10cm. Build an automatic misting system to maintain 70% air humidity, and roots will form in about 23 days at a temperature of 25°C.
Golden Rules for Transplanting Campsis
Timing Selection: Spring and Autumn Double-Season Window
The best time for transplantation is before sprouting in March-April or after flowering in September-October, when the day-night temperature difference is ≤8°C to reduce stress reactions. Avoid transplanting during the high summer temperatures to prevent root dehydration and leaf drop.
Operation Standards: Three-Step Protection Rule
Excavate with soil ball to retain a 30cm range of main roots, and wrap the root mass with jute cloth. The diameter of the planting hole should be 40% larger than the soil ball, with a 10cm layer of decomposed pine needles at the bottom. After planting, set up a 60% shade net for 15 days and apply芸苔素内酯 to the roots to promote new root growth.
Post-Transplant Care: Progressive Adaptation Management
Control watering frequency within 20 days after transplantation, keeping the soil slightly moist. Spray 0.1% potassium dihydrogen phosphate on the leaves every 10 days, and gradually increase sunlight after the new shoots grow 5cm. The first shaping pruning can be done in the following spring.
Through systematic propagation and scientific transplantation management, Campsis can form a 10㎡ vertical flower wall within three years. It is recommended to combine different propagation methods for a comprehensive approach, with divided plants flowering the same year, cutting plants shaping the following year, and seedlings suitable for mass cultivation. Mastering these core technologies will allow your Campsis to display its most magnificent vitality.
