Pruning and cutting back is important if your plants are to give their best display or crop, and to prevent them out-growing their space. Most woody ornamental plants are best pruned in the dormant season or, if they're spring flowering, as soon as the flowers begin to fade. Most herbaceous plants can be cut back after flowering or at the end of the growing season.

Step 1

How to prune your plants - pruning above a shoot
Pruning above a shoot

Where buds are visible, prune just above them to prevent leaving a long 'snag' of stem, which could encourage die-back. Allow 3-4mm so as not to damage the bud itself.


Step 2

Pruning at an angle

Where plants have alternately positioned buds on their stems, cut at a slight angle in the direction in which the bud is pointing.


Step 3

How to prune your plants - pruning straight
Pruning straight

If the plant has pairs of buds opposite each other, make the cut straight if you want both buds to grow. Alternatively, cut at an angle to remove one of the pair where a single stem is required.


Step 4

How to prune your plants - cutting out dead wood
Cutting out dead wood

Cut out any old or dead wood at the base of the plant to encourage vigorous new shoots from the base. You may need long-handled loppers for more leverage if the wood is thick and tough.


Step 5

How to prune your plants - rejuvenating old shrubs
Rejuvenating old shrubs

To rejuvenate old shrubs or coppice shrubs grown for the colour of their stems, hard prune all the stems down to 10-15cm above their base during the dormant season. Don't worry if no buds are visible.


Step 6

How to prune your plants - removing crossing stems
Removing crossing stems

Where stems are growing close together or crossing, cut out one to prevent them from rubbing together, which may damage the bark and cause die-back or disease.


Step 7

Trimming the stems back

Cut back flowered stems of herbaceous plants down to ground level, leaving the clump of leaves at the base. This stops the plants from wasting their energy on forming seeds.

Remove thick stems and branches using a pruning saw. For large branches, leave 1cm - 2cm where it joins the main stem, so that the tree or shrub can heal the wound.
