The summer season brings hot temperatures which, at their worst, can be lethal to trees. If you’re a homeowner with a yard full of trees, you are aware of the vital role they play in keeping our environment healthy. Therefore, when temperatures soar, it’s essential to take proactive measures to keep your trees alive. In this article, we’ll share tips to help keep your trees healthy and strong throughout the summer season.

Proper Watering

Water is essential for all living things, and trees are no exception. Proper watering is crucial to keep your trees healthy and hydrated during the hot summer months. Water your trees regularly during the morning or evening when the temperatures are lower. This will help your trees absorb the water more efficiently without losing water to evaporation.


Mulching is an excellent way to conserve soil moisture, regulate soil temperature, and suppress weed growth. During the summer heat, trees can lose up to 50% of their water to evaporation. Therefore, applying a layer of mulch around your tree’s base can help reduce water loss and keep root temperatures down.


Pruning is necessary to keep your trees healthy and safe. During the summer, it’s essential to remove dead or diseased branches. Pruning allows your trees to focus their energy on growing healthier branches, supporting their growth, and improving their general health. It’s best to prune your trees during the late fall or early spring to prevent damage during the summer months.

Protect Your Trees From Sunburn

Like humans, tree bark can be susceptible to sunburn, especially for younger trees or those with thin bark. Sun damage can lead to long-lasting scarring and, in some cases, even tree death. To protect against sunburn, it’s best to wrap paper tree wrap on trunks to shade your trees. Ensure the wrap is placed at a comfortable, tight, and sturdy height that can’t be easily dislodged by wind or pests.


Fertilizing is an excellent way to boost your tree’s resistance to disease, insect damage, and drought. However, be aware of the type of fertilizer you use and how much to apply. Over-fertilizing your trees can lead to runoff and pollute the environment. Before applying fertilizer, consult with a certified arborist or horticulturist to ensure your trees are receiving the proper nutrients.
