A heat wave can negatively affect even the healthiest gardens. Long periods of high temperatures and limited rainfall put lawns, trees, and shrubs under significant stress and, without the right care, grass can become brown and brittle, while trees may struggle to retain moisture.
For homeowners and businesses in Colchester, taking proactive steps during a heat wave can help maintain a healthy, attractive garden throughout the summer.
Water grass and trees the right way
One of the most effective ways to protect your lawn during a heat wave is to water thoroughly rather than little and often. This encourages grass roots to grow deeper into the soil, making the lawn more stronger during dry conditions. Watering early in the morning is ideal, as cooler temperatures reduce evaporation and allow moisture to reach the roots before it gets too hot.
Trees also benefit from thorough watering, particularly newly planted or young trees that have not yet established strong root systems. Mature trees are generally more tolerant to droughts, but long periods of hot weather can still affect their health.
Raise your mowing height
Avoid cutting your lawn too short during a heat wave, as longer blades of grass provide natural shade for the soil, helping it to hold moisture and protecting the roots from hot temperatures. Always mow with sharp blades to create clean cuts that minimise stress and encourage healthy growth.
Protect trees with mulch
Applying organic mulch around the base of trees is one of the best ways to improve moisture retention during a heat wave. A layer of mulch helps regulate soil temperature, reduces water loss through evaporation, and suppresses weeds that compete for valuable moisture. Leave a small gap around the trunk to prevent moisture build-up and reduce the risk of decay.
Watch for signs of heat stress
Regular inspections are important during a heat wave. Brown patches in the lawn, wilting leaves, early leaf drop, cracked soil, and dying branches can all signal that plants are struggling. Trees weakened by drought are often more vulnerable to fungal diseases and insect infestations, making inspections essential.
Routine tree surgery helps to keep trees healthy throughout the year, especially during a heat wave. Removing dead, damaged, or diseased branches improves airflow through the canopy and reduces unnecessary strain on the tree. Professional tree pruning also allows experienced arborists to identify potential problems before they become serious.
Avoid overfeeding your lawn
Many people assume fertiliser will help a struggling lawn, but applying high-nitrogen products during a heat wave can cause additional stress by encouraging rapid growth that requires even more water. It’s usually better to wait until cooler temperatures return before carrying out seasonal lawn feeding.
If water restrictions are introduced, prioritise watering newly planted trees rather than established lawns. Grass usually recovers once rainfall returns, while young trees can suffer permanent damage if they become severely dehydrated.
