Q. How and when should I prune my trumpet vine (Campsis radicans)?
A. Trumpet vine (Campsis radicans) is a vigorous, deciduous, woody vine. Pruning should be done in the late winter or early spring. For mature plants, trumpet creeper tolerates heavy pruning to control its spread and maintain a desired size. Prune annually, spur-pruning lateral shoots back to within two or three buds of the main stems. Remove weak and diseased growth. Renovate by cutting back all growth to within 12 inches of the ground to encourage strong new shoots to break from the base.
