Pruning Hebe
When and how — Hebe pinguifolia
Prune your hebe in April and May — the optimal month is usually May.
The next pruning window is April next year.
When to prune?
The shrub hebe is pruned in April and May.
Pruning time depends on when the shrub flowers.
The rule of thumb for ornamental shrubs: spring-flowering shrubs (forsythia, lilac, flowering currant) are pruned immediately after flowering, because they set their buds on last year's wood. Summer-flowering shrubs (buddleia, paniculata hydrangea, hardy hibiscus) are pruned in March, because they flower on wood produced this season. Get the timing wrong and you cut off this year's buds. Evergreen shrubs (yew, box) are best pruned around Midsummer (24 June): the first flush of growth is finished and the plant still has time to seal the wounds before winter.
How to prune hebe
Hebe pinguifolia requires minimal pruning, which is one reason it's valued as a low-maintenance evergreen. Prune lightly in April or May, after the risk of hard frost has passed but before the main flush of new growth. Spring timing allows cuts to heal quickly and encourages bushier growth through the summer. Use clean, sharp secateurs or hand pruners. Focus on removing any frost-damaged, dead, or diseased stems first—cut back to healthy wood where you can see green tissue beneath the bark. Then lightly trim back the previous year's growth by about one-third to maintain a compact, rounded shape and prevent the plant from becoming leggy. Avoid cutting into old, thick wood, as hebes are reluctant to regenerate from bare stems and may not recover well from hard pruning. If your hebe has become straggly or overgrown, resist the temptation to cut it back severely. Instead, prune more frequently but lightly, shaping it over two or three seasons. Deadheading spent flower spikes in late summer encourages a tidier appearance and may prompt a second, lighter flush of blooms, though this isn't essential for plant health. Hebes grown in exposed or coastal sites may suffer wind scorch or dieback over winter. In early spring, assess the damage and prune out affected growth. If the plant has become lopsided, trim the longer shoots to restore symmetry. Always step back regularly as you work to check the overall shape, aiming for a natural, domed outline rather than a rigid form.
Common mistakes
✗ Hard-pruning all hydrangeas in early spring
Mophead hydrangea (Hydrangea macrophylla) flowers on old wood — cut it back in March and you get no flowers. Paniculata flowers on new wood and can be cut back hard. Check the species first.
✗ Trimming everything to the same length
Looks 'chopped' and weakens the shrub. Instead, remove one in three of the oldest stems each year right down to the base (renewal pruning). This keeps the shrub vigorous and natural in shape.
✗ Pruning in summer heat
Fresh cuts dry out quickly in full sun and become an entry point for fungal disease. Wait for an overcast day or postpone until autumn.
Combine with feeding
In April you can combine pruning with feeding — efficient, and you only disturb the plant once. Read the full care guide for hebe →
Too late this year? Here's what to do
Better to wait than prune at the wrong moment. The next optimal window is April next year. Until then: leave the plant alone — only remove dead or diseased wood (which you can do year-round).
