June is one of the busiest months in the garden – and a quick prune now can make all the difference. With plants putting on fast, fresh growth, a light trim will help keep shrubs, climbers, hedges and fruiting plants looking neat, healthy and full of life.
The key is gentle maintenance, not a hard cut back. A well-timed prune can encourage more flowers, stronger stems and lush foliage, while thinning fruit trees and tomatoes helps improve airflow and lets more sunlight reach developing fruit.
‘Think of it as a seasonal refresh rather than a major chop,’ says Julian Palphramand, head of plants at British Garden Centres.
These seven plants will all benefit from a prune this month.
1. Deciduous Magnolia
‘Once your deciduous magnolia has finished its spring display, it’s a good time for a gentle tidy-up,’ says Julian. ‘Keep pruning to a minimum and just remove any dead, damaged or crossing branches, as magnolias don’t tend to respond well to anything too heavy handed.’
2. Clematis Montana
Clematis montana is a wonderfully vigorous climber, but it can quickly outgrow its space if left unchecked, cautions Julian: ‘Pruning straight after flowering helps keep it under control and encourages plenty of strong new growth for next year’s flowers.’
3. Viburnum Tinus
‘After flowering, viburnum tinus benefits from a light trim to keep it looking neat and compact,’ says Julian. ‘Removing spent blooms and any straggly growth will help maintain a well-shaped plant and promote fresh, healthy shoots.’
4. Philadelphus
Philadelphus, or mock orange, should be pruned as soon as it finishes flowering, Julian advises. ‘Taking out a few of the oldest stems at the base each year keeps the plant rejuvenated and ensures a good supply of new growth for future blooms.’
5. Weigela
‘Weigela is best pruned once flowering has finished, by cutting back the stems that have just bloomed to a strong shoot below,’ says Julian. ‘This helps keep the plant nicely shaped and encourages a more generous display the following year.’
6. Deutzia
Deutzia is another spring flowering shrub that benefits from pruning straight after flowering: ‘Cut back the flowered stems to fresh growth, and if needed, remove a few older stems at ground level to keep the plant open and full of vigour,’ says Julian.
7. Rhododendron
‘Once flowering has finished, it’s worth deadheading rhododendrons to keep them looking tidy and to direct energy into new growth,’ Julian advises. ‘You can also lightly shape the plant at this stage, but avoid any hard pruning, as this can impact next season’s display.’
• Hot weather warning
Avoid pruning during very hot spells as newly exposed stems may scorch in intense sun.
