Campsis grandiflora (Chinese Trumpet Vine)

How to grow Campsis grandiflora (Chinese Trumpet Vine) in NZ

Campsis grandiflora (Chinese Trumpet Vine) grows best in full sun with fertile, free draining soil and a warm, sheltered position. Strong sunlight encourages vigorous growth and the best flowering display. Plant beside a sturdy pergola, fence, arch, or trellis and tie young stems to the support until they become established. Water regularly during the first growing seasons and during prolonged dry periods. Apply compost or a balanced garden fertiliser in spring to support healthy growth. Avoid excessively rich feeding, which can encourage foliage at the expense of flowers. Mulch around the root zone to conserve moisture while keeping mulch clear of the main stems.

Campsis grandiflora (Chinese Trumpet Vine) care tips

Campsis grandiflora (Chinese Trumpet Vine) benefits from regular pruning to control its vigorous growth and encourage a tidy flowering framework. Prune during winter when the plant is dormant, removing weak, damaged, or poorly positioned stems and shortening side shoots as required. Train strong stems onto a durable support and check ties periodically so they do not cut into expanding growth. Water during extended dry periods, particularly while plants are establishing. A spring application of balanced fertiliser can support healthy growth, but avoid excessive nitrogen. Remove unwanted shoots promptly if the vine spreads beyond its allocated space. Good sunlight and airflow will help maintain healthy foliage and reliable flowering.

Campsis grandiflora (Chinese Trumpet Vine) size, spacing, and growth rate

Campsis grandiflora (Chinese Trumpet Vine) is a vigorous climber that can reach approximately 5 to 10 m in height or spread when provided with suitable support. Growth is fast in warm, fertile conditions, making it useful where substantial seasonal coverage is required. Allow at least 2 to 3 m between plants when using several vines along a large fence, pergola, or other structure. Its ultimate size can be restricted considerably with regular winter pruning and training. Because mature stems become woody and heavy, the support should be strong enough to carry the plant long term. Adequate spacing also improves airflow and makes ongoing pruning and maintenance easier.
