Pruning English Holly for Berry Production and Shape

English holly (Ilex aquifolium) pruning balances berry display with desired form. Berries form on previous year's wood.

Pruning Principles

• Timing: Late winter/early spring (before new growth) OR immediately after flowering.
• Severity: Light pruning preserves berries; heavy renovation reduces crop for 1–2 years.
• Shape: For dense bush: tip-prune frequently. For tree form: remove lower limbs, select central leader.

Renovating Overgrown Hollies

1. Year 1: Remove ⅓ oldest stems to ground.
2. Year 2: Remove next ⅓.
3. Year 3: Remove remaining old wood.
4. Thin crossing branches annually.
