Pruning of Campsis Lour.
Campsis Lour. requires minimal pruning, but some occasional maintenance pruning is necessary to keep the plant healthy and attractive. Prune the plant in late winter or early spring before new growth begins. Remove dead or damaged wood, as well as any weak or crossing branches that may hinder air circulation.
You can also prune long shoots to maintain the plant size and shape, but avoid excessive pruning that can reduce flowering. Always use clean and sharp bypass pruners to make clean cuts and avoid spreading diseases.
Propagation of the Campsis Lour. Plant
The Campsis Lour. plant, commonly known as trumpet vine, can be propagated through several methods such as seed, cuttings, and layering.
Seed Propagation
Seed propagation is the most common method used for Campsis Lour. plant. Collect seeds from matured fruits that have fallen or are about to fall from the plant. Soak the seeds in water for 24 hours before planting. Sow the seeds in a mix of well-draining compost and sand. Cover the seeds lightly with soil and water them gently. Place the pots in a warm, bright location, keeping the soil moist until germination occurs.
Cuttings Propagation
Cuttings are another propagation method that is commonly used with Campsis Lour. plant. Take cuttings of semi-hardwood stems during the growing season, typically in the early summer, using a sharp knife. Remove the lower leaves of the cutting and dip the cut end into rooting hormone. Place the cutting into a pot filled with well-draining soil and sand. Keep the soil moist and place the pot in a warm and bright location. Roots should form in about four to eight weeks, which can then be transplanted to a larger pot or directly into the ground.
Layering Propagation
Layering is also a popular propagation method for Campsis Lour. plants. Choose a matured and healthy stem that is close to the ground and without any damage. Gently bend the stem towards the soil and make a shallow slice in the branch's underside. Coat the slice with rooting hormone, and then cover the slice with compost or soil, gently pressing down to secure it. Water the soil and wait for the stem to form roots. Once roots have developed, you can then separate the new plant from the parent plant and plant it in a pot or directly into the ground.
