Pruning shrubs periodically keeps them full of foliage and flowers. We prefer to prune most shrubs by hand, which maintains the shrubs natural form.

Cabling and bracing trees involves adding hardware to the tree to reduce the risk of failure and prolong the life of the tree. We have been installing support systems for twenty years.
