As a professional gardener based in Staffordshire, I've spent over 15 years pruning all sorts of trees, with plum trees being a particular favourite of mine. Pruning plum trees is not just about shaping them for aesthetic appeal; it's crucial for their health and fruit production. In this article, I'll guide you through the right amount to prune your plum trees, ensuring you have a fruitful harvest in the coming seasons.
Quick Answer
For plum trees, aim to remove about 20% of the previous year's growth each year for the best results.
When to Prune Plum Trees
The timing of your pruning can make a significant difference. In the UK, and specifically here in the Midlands, the best time to prune plum trees is in the mid to late summer. This timing helps prevent the spread of silver leaf disease, which can be more prevalent during the damp winter months.
How Much to Prune
Generally, you should look to prune about 20% of the tree's new growth each year. This means focusing on the shoots that have grown during the current year. By doing so, you allow sunlight to penetrate the tree's canopy, encouraging healthy fruit development.
Pruning Techniques
Start by removing any dead, damaged, or diseased wood. Next, thin out the centre of the tree to improve air circulation. This is particularly important in the Midlands, where the climate can be a bit damp. Finally, cut back about a third of the new shoots, focusing on maintaining an open centre and balanced shape.

Benefits of Proper Pruning
- Encourages better fruit production
- Improves tree health and prevents disease spread
- Enhances the overall shape and strength of the tree
Common Mistakes to Avoid
Many gardeners make the mistake of pruning too much or at the wrong time. Here in Staffordshire, it's essential to avoid pruning in the winter to prevent silver leaf disease. Also, never prune more than 30% of the tree's overall structure in a single year, as this can shock the tree and reduce fruit yield.
Frequently Asked Questions
Can I prune plum trees in winter?
It's best to avoid winter pruning due to the risk of silver leaf disease. Stick to mid to late summer pruning.
How can I tell if I've pruned too much?
If the tree looks sparse or struggles to produce leaves in spring, you may have over-pruned. Aim for a balanced shape with sufficient foliage.
What tools should I use for pruning?
Use sharp secateurs for smaller branches and a pruning saw for larger limbs. Always sterilise your tools to prevent disease spread.
