June – when to prune evergreen shrubs

Timing is crucial. Avoid pruning in autumn or winter, as cuts made then may not heal fully before cold, damp weather sets in, increasing the risk of dieback or fungal plant infections. Early to mid-spring pruning allows the plant to recover swiftly during the growing season.

Start by removing dead, damaged, mis-shaped or diseased branches with clean, sharp secateurs in order to reduce risk of spreading disease from one plant to another. For shaping, use loppers or shears to trim the outer growth, maintaining a natural shape rather than forcing symmetry. For dense shrubs, thin out crowded stems to improve airflow and light penetration.nd manageable year-round in the UK garden.

1. Box (Buxus Sempervirens) – Traditionally used for topiary as well as hedging, Box benefits from light trimming in May or June. Avoid cutting into old wood, as it may not regenerate.
2. Cherry Laurel (Prunus Laurocerasus) – Best pruned in late spring. Use secateurs to cut back overgrown shoots to a leaf joint, avoiding bare stems. This keeps the shrub bushy and compact.
3. Holly (Ilex Aquifolium) – Can be pruned from late spring to early summer. Remove overly long or leggy shoots and any inward-facing branches to maintain a good structure.
4. Photinia × Fraseri ‘Red Robin’ – Prune in late spring or after its red flush of young leaves fades. Regular trimming encourages repeated red growth and keeps the shrub tidy.

Routine pruning helps evergreen shrubs thrive, ensuring they stay attractive, healthy, and manageable year-round in the UK garden.
