The recent heatwave across the UK has reminded us just how challenging prolonged periods of hot, dry weather can be, not just for us, but for our trees too.
Whilst mature trees are remarkably resilient, extended spells of high temperatures and limited rainfall can place them under significant stress. Younger trees and those recently planted are particularly vulnerable, making summer tree care more important than ever.
How Does Hot Weather Affect Trees?
Trees rely on water to transport nutrients from their roots to their leaves. During a heatwave, the ground dries out quickly, making it much harder for roots to absorb enough moisture.
Common signs of heat stress include:
- Leaves turning yellow or brown around the edges
- Wilting or curling foliage
- Early leaf drop
- Dead twigs or branches
- Cracks developing in the soil around the base of the tree
While some trees recover once rainfall returns, prolonged drought can weaken them, leaving them more susceptible to pests and disease.
Watering Your Trees Properly
One of the biggest mistakes people make is watering little and often.
Instead, water deeply once or twice a week, allowing the moisture to soak well into the root system. This encourages roots to grow deeper, helping the tree become more drought-tolerant.
Young trees should be your priority, as they haven’t yet established extensive root systems.
Top tip: Water early in the morning or late in the evening to minimise evaporation.
Add Mulch Around the Base
Applying a layer of organic mulch around the base of your tree can make a huge difference during hot weather.
Mulch helps to:
- Retain moisture in the soil
- Keep roots cooler
- Reduce weed growth
- Improve soil health over time
Leave a small gap around the trunk to prevent excess moisture building up against the bark.
Avoid Heavy Pruning During Heatwaves
Although some pruning can be carried out during summer, major reductions or extensive pruning should generally be avoided during periods of extreme heat.
Removing too much foliage reduces the tree’s natural shade, increasing stress and moisture loss.
If your tree requires maintenance, a qualified arborist can advise on the most appropriate timing and the safest approach.
Check for Dead or Damaged Branches
Hot weather, combined with previous storm damage, can cause weakened branches to fail unexpectedly.
If you notice:
- Dead limbs
- Cracks in large branches
- Hanging branches
- Significant dieback
It’s worth arranging a professional inspection before they become a safety risk.
Give Your Tree Space to Breathe
Overgrown canopies can reduce airflow and create unnecessary competition for light and water.
A professionally carried out crown reduction or crown thinning can improve the tree’s overall structure while maintaining its natural appearance and long-term health.
Every tree is different, so any work should be tailored to its species, age and condition.
