Helping a lawn through hot, dry weather
Heat-stressed grass needs less traffic, sensible mowing and careful decisions about irrigation rather than a fixed daily watering habit.
Recognise heat and drought stress
Grass may grow more slowly, lose colour or become temporarily dormant during hot dry spells. Not every yellow area is dead or caused by the same problem. Check the soil and the condition of individual plants before applying fertiliser or mowing shorter. Persistent patchiness may also reflect shade, compaction, thatch or disease, so the right response depends on the actual cause.
Reduce wear and mowing stress
Avoid heavy foot traffic and games on badly stressed lawns where practical. Raising the mowing height can leave more leaf surface and reduce the amount of green tissue removed at one cut. Never remove an excessive proportion of the leaf at once, and avoid mowing during the fiercest heat. A blunt blade tears leaves and makes stressed grass look worse; keeping equipment sharp is a simple, practical measure.
Water only with a plan
If watering is justified and local restrictions allow it, aim to wet the root zone adequately rather than giving tiny daily surface splashes. Soil type, rooting depth and recent rainfall determine how much is appropriate. Check the result below the surface and adjust to actual conditions. Some lawns can tolerate temporary summer dormancy and recover with cooler weather; maintaining a perfectly green surface at all costs is not always a sensible use of water.
Delay unnecessary renovation
Avoid aggressive scarification or heavy feeding during extreme heat and drought. Wait for more suitable growing weather to address compaction, overseeding or persistent bare patches. If the lawn suffers in the same area each year, reconsider whether that location has enough light and moisture for the chosen grass. A smaller lawn, different seed mix or other groundcover may be a better long-term solution.
Before you begin: three practical checks
- Raise mowing height when appropriate
- Reduce traffic on stressed grass
- Check the soil before irrigating
