Pruning Privet
When and how — Ligustrum ovalifolium
Prune your privet in March and April — the optimal month is usually April.
The next pruning window is March next year.
When to prune?
The shrub privet is pruned in March and April.
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 privet
Privet tolerates hard pruning and responds with vigorous regrowth, making it ideal for formal hedges. The main pruning window is March and April, just before the spring flush of growth. Pruning during these months ensures you shape the plant before it puts energy into new shoots, and any cut surfaces heal quickly as sap rises. For an established hedge, use sharp hedging shears or a hedge trimmer to cut back the previous season's growth by about half, creating a slight taper with the base wider than the top to allow light to reach lower branches. This prevents the base from becoming bare and leggy. A second light trim in late June or July keeps the hedge tidy through summer, though this is optional and should be avoided if you want to enjoy the frothy white flowers that appear in summer. Flowering occurs on new wood, so March pruning does not eliminate blooms. Neglected or overgrown privet can be renovated by cutting back hard into old wood in March—even down to 30–50 cm from the ground. It will resprout readily from the base. Spread hard renovation over two years if you prefer, tackling one side of the hedge in year one and the other in year two, to maintain some screening. Remove any dead, damaged, or crossing branches whenever you spot them. Wear gloves when pruning; the foliage and berries are mildly toxic and can irritate skin. Clean tools after use to prevent the spread of disease.
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 March and April you can combine pruning with feeding — efficient, and you only disturb the plant once. Read the full care guide for privet →
Too late this year? Here's what to do
Better to wait than prune at the wrong moment. The next optimal window is March next year. Until then: leave the plant alone — only remove dead or diseased wood (which you can do year-round).
