Summer Drought: Caring for Trees and Hedges in the Heat

Drought doesn't just stress lawns — trees and hedges suffer too, and the damage can be longer lasting. Here's how to look after them through a hot, dry summer.

Spotting drought stress in trees

  • Wilting or curling leaves that don't recover in the cool of evening
  • Early leaf drop or scorched, brown leaf edges
  • Browning needles on conifers and evergreens Young and newly planted trees are most at risk, but even established trees can struggle in a prolonged drought.

Watering trees the right way

  • Water deeply and slowly — a slow, deep soak at the root zone is far better than frequent light watering
  • Target the roots — water the area around the drip line (the spread of the branches), not the trunk
  • Newly planted trees need regular deep watering for the first couple of years — a good soak once or twice a week in dry weather
  • Mature trees generally cope, but a deep soak during extended drought helps protect them
  • Use a watering ring or slow-release bag for young trees to get water down to the roots

Mulch matters

A layer of organic mulch around the base (not touching the trunk) locks in moisture, keeps roots cool and suppresses weeds. Aim for a 5–7cm layer over the root area.

Hedges in a drought

  • Water newly planted hedges deeply and regularly
  • Avoid trimming in extreme heat — a cut during drought stresses the plant further; wait for cooler weather if you can
  • Mulch the base to retain moisture

Plan ahead

The best protection against drought is healthy, well-established plants with deep root systems. Good aftercare in the first few years, regular mulching and avoiding over-pruning all build long-term resilience.
