How to prune holm oak

Late summer (August–September) for topiary/hedging; late winter for structural tree pruning. For hedges and topiary, clip with shears or hedge trimmers in late summer once new growth has hardened. For tree form, remove dead or crossing branches at the collar in late winter. Holm Oak tolerates hard renovation but do it in stages over 2–3 years on old hedges to reduce shock.

Once or twice per year for formal hedging; every 3–5 years for trees. Holm Oak (Quercus ilex) is often grown as a formal clipped hedge or topiary in gardens, tolerating hard shearing well. As a free-growing tree it needs structural pruning when young, then mainly deadwood removal. Prune or clip in late summer after growth hardens to maintain shape without stimulating excessive regrowth.
