Prime Time for Pruning

Late winter is an excellent time to prune shrubs and trees, while they are safely dormant.

Dormant Pruning Tips

Kunso Kim, head of collections and curator, suggests you consider these different approaches.
Selective pruning: To shape the shrub or control its size somewhat, go branch by branch, choosing the branches you want to keep and removing those that are too long, superfluous or causing a tangle. Using sharp, clean pruners, prune just above the place where one stem branches off from another; don’t cut in the middle of a branch between joints, which will cause bristly, unsightly growth.
