1. Cuttage propagation: Cuttage is carried out in spring or autumn every year.Choose strong, annual cuttings, about 10 to 15 centimeters long, with the leaves cut off.Also prepare a breathable, soft substrate.After preparation, insert the cutting directly into the line, the depth is half of the cutting.Later, pay attention to moisturizing and temperature control, more than 20 days can take root.
2. Sowing and propagation: Sowing is carried out in spring.The seeds should be full and robust, and first soaked in clean water for two or three days to germinate.Sprinkle directly on the soil surface after germination treatment.The humidity is controlled in the later period, and the leaves can germinate and grow soon.
3. Layering propagation: The layering method is usually carried out in July.Pull the long and strong branches to the ground, bury them with soil in sections, expose the buds, pay attention to moisturizing treatment, take root in about 50 days, dig out and transplant them after rooting.
The growth rate of Campsis grandiflora is relatively fast. If properly maintained, the branches can grow more than 2 meters each year.Therefore, when potted plants are planted, large pots should be used, and large enough pots need not be repotted every year.If the flowerpot is small, after a year of growth, the space will be insufficient, you need to change the pot frequently.
