Should Hedges Be Pruned?

Ideally, hedges should be pruned in late winter, when plants are dormant and haven't produced buds—particularly if you're cutting back drastically. "You don't want them to break bud before you prune because you want the plant's energy to go toward producing new growth where you want it," says Roger.

When should I not trim my hedges?

Late spring, early fall,or winter (when the hedges are fully dormant) are the best times for pruning hedges. Don't prune hedges during very hot, dry weather, and prune well before your first frost date.

What time of year do you cut back hedges?

When to trim hedges. New hedges require formative pruning for their first couple of years after planting. Formative pruning is usually carried out in winter or early spring. After this, maintenance trimming is carried out, usually once a year for informal hedges and twice a year for formal hedges.
