Pruning Your Boxwood. 1  1. Know when to prune your tree. Prune boxwood shrubs at any time between the last expected spring frost and six weeks prior to the first expected fall frost. 2  2. Use sharp bypass pruners to trim off dead, injured or diseased branches. Prune them off all the way to the base of the branch.
Boxwood can be pruned easily and has the ability to grow from old wood. To maintain trimmed forms and hedges you need to prune them twice a year. The first time should be done around late May or mid-June, after the first growth spurt. You can prune for a second time in September or October so the plants will look tight when winter comes. It is best to do it when the weather is cloudy to reduce the chance of burning the leaves. By cutting them you damage part of the leaves and these will turn brown.
