Heat Stress & Drought: Protecting Our Trees
With prolonged hot, dry weather becoming more common, our trees are under increasing pressure. Heat stress and drought can have serious impacts—not just on young or newly planted trees, but on mature ones too.
What’s happening?
High temperatures increase water loss through leaves, while dry soil limits how much water roots can absorb.
Drought conditions mean trees can’t replace lost moisture, leading to dehydration and stress.
You may notice signs like wilting leaves, early leaf drop, scorched or browning edges, and reduced growth.
Why does it matter?
Stressed trees are more vulnerable to pests, diseases, and long-term decline. Even if they survive a drought period, the damage can weaken them for years to come.
How can we help?
Water wisely – Deep, slow watering is more effective than frequent light watering, especially for young trees.
Mulch matters – Apply a layer of mulch around the base (but not against the trunk) to retain soil moisture.
Avoid extra stress – Limit pruning during extreme heat and avoid compacting the soil around roots.
Monitor regularly – Early signs of stress can be managed if caught in time.
Trees are vital for shade, biodiversity, and cleaner air—so giving them a little extra care during hot, dry spells makes a big difference
Let’s look after them, so they can keep looking after us
