August 2021 Tree Talk: CARING FOR TREES IN THE SUMMER HEAT

Posted on June 28, 2024 at 1:57 PM by Nicole Newsom

Establishing a summer tree care plan is essential to keeping trees healthy during hot days, droughts and summer storms. Follow these tree care tips to make sure your trees are getting the support they need to survive and thrive throughout the summer.

Mulching

Most trees love oxygen-rich soil. Mulch helps to retain soil moisture, suppress weeds, reduce water competition and remove the need to mow near the trunk, protecting the root system. TreesAreGood.org, managed by the International Society of Arboriculture, recommends two to four inches of mulch. Avoid piling mulch against the root flare, where roots begin to fan out from the trunk. Mulch should ideally cover the area underneath the canopy.

Fertilizing

Slow-release fertilizer should be given to trees in early spring, followed by treatment in the fall.

Watering

The amount of water depends on the soil type, recent weather, the age/type of tree and nearby vegetation. Intense heat during the summer can often evaporate water before it’s able to be taken in by the roots.

Some tips for watering:

  • The Georgia Forestry Commission recommends watering at night or in the early morning when it’s cooler.
  • Water should be delivered slowly, giving the roots enough time to soak it up. 
  • Give your trees lots of water periodically to encourage a deep root system. Briefly watering on a daily basis will foster a shallow root system and root rot.
  • Overwatering is problematic as it essentially drowns the root system.

Note: Consult a certified arborist to determine water and fertilizer regimens appropriate for your trees.
