|Are the root systems of evergreen clematis invasive? Will they displace walkways or rock walls? How do you prune clematis?|
|Clematis roots shouldn't become a problem. They are often planted next to walls and arbors for support. The roots need to be kept cool, so plant under a shrub, or some other place where the roots will be in the shade and the top of the plant will be in the sunshine. Train young clematis up a support by tying the vines as they grow. Pinch or rub out any misplaced stems as they appear. General pruning guidelines for clematis include: spring-blooming clematis bloom on the previous year's wood. Cut back after flowering.
To keep evergreen clematis attractive, prune out tangled and dead stems all summer. The plant is slow to become established, but will grow vigorously once it gets a foothold.
