How to prune campsis
Pruning the vine once a year will help keep it from spreading and build a strong frame of woody branches from which flower-bearing shoots will grow. Formative pruning involves creating a strong woody framework by cutting stems back to 15cm above the ground after planting to encourage new growth. Tie two or three of the strongest resulting shoots into the trellis or other support structure, and remove the rest.
After two or three years, the framework of stems should be complete. In subsequent years, spur-prune the sideshoots back to within two or three buds of the permanent framework in late winter or early spring. Remove any diseased or damaged stems. Campsis can also be cut back hard if it has become overgrown. Cut all the stems back to 30 cm from the base in February or March. Then train the vine like you would a new plant.
How to care for campsis
Keep your trumpet vine well watered during the first year. They have fairly good drought tolerance once established, but grow better if watered in dry periods. Plants in containers benefit from regular watering and feeding with a high potassium liquid feed, such as tomato fertiliser or homemade comfrey tea, to encourage flowering. Adding a layer of mulch once a year in spring or autumn helps retain moisture in the soil and prevent plants drying out.
Campsis can take a few years to flower freely after planting. If your mature trumpet vine isn’t flowering, it could be because it was planted in too much shade, because it was fertilized with nitrogen-rich feed that promotes leaf growth over flower growth, or because it was pruned too late in the spring. Trumpet vines require full sun to ripen new wood and help the plant produce a profusion of blooms.
If foliage starts to turn yellow or brown, or leaves fall off, it is worth checking the that rootzone is not too dry or too wet. Trumpet vines can be overwintered successfully in many parts of the UK, provided they are grown in a sheltered location such as against a sunny wall.
