Understanding Summer Stressors for Trees

Summer brings several environmental stresses that challenge tree health. Here are the most common:


During summer, the high temperatures can cause leaves to wilt or drop early and edges to brown. This weakens the tree and makes it more sensitive to diseases.

Low Soil Moisture

Low soil moisture is another challenge. Without enough water, trees can’t get the nutrients they need, leading to poor growth and increased vulnerability to pests.

Increased Pest Activity

Pests are more active in the summer. They take advantage of weakened trees, causing further damage. Some signs of pest problems you may watch out for are holes in leaves, sticky residue, and unhealthy-looking bark.

Essential Summer Tree Care Practices

You can follow these key tree care tips to help them survive the summer heat:

Deep Watering

Watering is critical in summer—water trees deeply a few times a week instead of shallowly every day. Early morning or late evening is the best time to do it.

Proper Mulching

Mulch helps retain soil moisture and regulate temperature. Apply a 2-4 inch layer of mulch around the tree base to prevent fungal growth and maintain the soil cool and moist. Be careful to keep the mulch far from the trunk, as it can suffocate the plant.

Light Pruning

Prune trees in summer to remove dead or damaged branches and improve air circulation. Use sharp, clean tools to cut just above a bud or branch. Avoid heavy pruning (this is better during winter or early spring), as it can stress the tree further.

Preparing Trees for Summer Storms

Summer storms can be harsh. To minimize storm damage, we recommend you do the following:

  1. Regularly inspect for weakened parts and remove them.
  2. Secure young trees with stakes for added stability.
  3. Ensure proper drainage around trees to prevent waterlogging.

When to Seek Professional Help

Sometimes, it’s best to call someone experienced in properly caring for trees. They can help you treat severe pest infestations and significant storm damage or even get advanced tree health assessments.

To choose a reputable tree services provider, check reviews and certifications and ask for references. This will ensure you get the best service to keep your trees healthy.
