Pruning shrubs can be a daunting task but is pretty straightforward once you know a few basic rules.
Deciduous Shrubs: When to Prune
Deciduous shrubs can be hard pruned in July – August while they are dormant. There is also less risk of any infection in the cut branches.
Evergreen Shrubs: Light vs. Hard Pruning
Evergreen shrubs can generally be pruned lightly anytime of the year and hard pruned in late Summer to achieve the desired size and shape. Always cut at a 45° angle, above a leaf node or bud to ensure a healthy cut.
Flowering Shrubs: Time It Right
Flowering shrubs should be pruned according to individual flowering seasons to avoid removing the next season’s flowering branches. Shrubs like Buddleja, Tecoma, Solanum, Potentilla, Ceratostigma and Hypericum can be pruned hard in July to ensure plenty of blooms late Summer into Autumn.
Climbers like Clematis, Honeysuckle and Jasmine that have become straggly can be cut back to keep them tidy and healthy
When pruning any deciduous or evergreen shrubs that bear berries, remember to leave some berries for the birds to enjoy.
The best time for hard pruning Bush Roses is late July and August. Remove any diseased wood and leaves, making sure any fallen leaves are cleared from around the base of the plant. Miniature and Standard Roses will also benefit from some pruning to retain their height and shape. Climbing Roses need to have old wood trimmed. Aerating the soil around all roses after pruning will ensure better airflow.
Tool Maintenance: Prepare Before You Prune
Before beginning any pruning it’s important that your secateurs, shears and saws are sharpened and well-oiled to avoid damage to branches. Always start by pruning a few branches, then checking the shape is ok before continuing. Concentrate on removing dead, diseased or damaged branches.
