  • Dormant Pruning Tips

    Kunso Kim, head of collections and curator, suggests you consider these different approaches.

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.
