Is Summer a Good Time to Prune Trees? Here’s What You Need to Know

Summer is the perfect season to enjoy your garden, whether you’re soaking up the sun, planting new flowers, or entertaining friends. If you have trees on your property, you might be wondering:

Is summer tree pruning a good idea?

In some cases, yes. But not always.

While certain trees benefit from light pruning in summer, others can be harmed by it. Knowing when to prune trees in the UK is key to keeping your trees healthy and looking their best.

This quick summer pruning guide covers:

✅ What happens when you prune in summer
✅ Which trees can and can’t be pruned
✅ Pro tips for safe, effective trimming
✅ When it’s time to call a professional

What Happens When You Prune in Summer?

Spending more time outside might tempt you to tidy up overgrown branches. But before you start cutting, it’s important to understand both the benefits and risks of summer pruning.

Benefits

• Shape control – keeps your tree looking neat and well-formed

• Disease removal – cutting out dead or damaged branches improves health

• Growth management – ideal for slowing down fast-growing species

Risks

• Sun scorch – removing too much foliage exposes branches to direct sunlight

• Weakened health – heavy pruning reduces energy storage, leaving trees more vulnerable

• Stress – pruning during heatwaves or dry spells can push a tree into decline

Tip: Light pruning is usually safest in late spring to early summer, but this varies depending on the tree species.

Which Trees Can Be Pruned in Summer?

Not all trees dislike summer pruning. In fact, some thrive with the right care.

You can usually prune:

• Fruit trees – like apple, cherry, and plum (after fruiting)

• Evergreens – such as yew or Leylandii

• Fast-growing species – like willow or poplar

Just make sure the tree is:

• Well-established

• Free from disease or drought stress

• Being pruned lightly and with purpose

Which Trees Should Be Avoided in Summer?

Some trees are particularly sensitive and should not be pruned during the warmer months.

Avoid summer pruning if your tree is:

• Recently transplanted – it needs time to settle and grow roots

• Stressed – due to drought, pests, or disease

• A vulnerable species – like oak or American elm, which are prone to pests and diseases if pruned in summer

If you’re unsure, a professional Tree Inspection can help assess your tree’s health and timing.

Pro Tips for Safe Summer Tree Pruning

If you’re doing small pruning jobs yourself, follow these tips to avoid damaging your tree or injuring yourself.

✔️ Do:

• Use clean, sharp tools

• Cut just above a node or lateral branch

• Prune only 10 – 15% of the crown at once

• Choose cooler parts of the day if possible

❌ Don’t:

• Over-prune (it weakens the tree and encourages unwanted regrowth)

• Prune during drought or extreme heat

• Attempt large or risky jobs without the right equipment

Considering crown thinning in summer? This should only be done lightly and strategically, never overdo it.

When to Call a Tree Surgeon

While light pruning can be a DIY job, there are times when it’s best (and safest) to call in the pros.

Call a tree surgeon if:

• The tree is tall or difficult to access

• It overhangs buildings, roads, or rivers

• Ladders, hoists, or safety gear are needed

• You’re unsure about the species or condition
