ing the vine from its support. Those with tendrils and twining vines can become very entangled in other plants, and they can cause excessive damage if you simply pull at the cut branches. Additional cuts to loosen the vine will be necessary.
Frequent pruning and removal of those that grow with hold-fasts will reduce the amount of damage that they may cause to bricks and mortar.

pruning principles
The same principles for pruning shrubs apply to vine. Cut at a lateral branch, twig, or bud; and do not leave a stub. Prune dead, weak, and thin wood back to healthy wood. Thin old and weak stems annually to encourage new growth. Thin crowded stems by cutting them to the ground. Prune most vines in the dormant season before new growth begins, except for early spring-flowering vines, which should be pruned after they flower since the growth that develops after pruning produces buds for next year. Vines that flower on growth made in the current year, as do many of the hybrid clematis, can be pruned in early spring a few feet to a few inches above the ground.
