Help Your Trees and Shrubs Beat the Heat

Mulching

Mulch is a protective layer for your plants, protecting roots from the harsh sun and holding moisture in the soil. A thick layer of organic mulch, such as wood chips or straw, conserves water and moderates soil temperature during hot spells. Spread mulch around the base of your trees and shrubs, but leave a small gap around the trunk to prevent rot. If you prefer a more hands-off approach, hire a tree care company in Jefferson to determine suitable mulch material and handle the application process.

Pruning

While it is tempting to prune damaged or excess branches during summer, it’s important to be cautious. Pruning can expose more of the plant to the sun, increasing its vulnerability to heat stress. Instead, focus on light pruning to remove dead or diseased branches and avoid heavy pruning and the subsequent problems like deterioration, death, and premature tree removal. This approach helps maintain the plant’s natural canopy, providing shade for its roots and reducing water loss through transpiration.

Shade Protection

In extreme heat, providing temporary shade for young or sensitive plants can be a lifesaver. Erecting shade cloth, netting, or even using patio umbrellas can protect your trees and shrubs from the sun’s direct rays. This is important for newly planted or vulnerable species that haven’t yet established deep root systems. Shade protection reduces the amount of stress on these plants, allowing them to cope better with the heat. If you notice signs of heat stress despite your efforts, consult a tree service professional for a more effective solution.

Fertilizing: Timing is Key

Fertilizing during the peak of summer can sometimes do more harm than good. High temperatures combined with fertilizer can lead to nutrient burn, damaging the roots and stressing the plant. Instead, apply fertilizer in the spring or fall when the weather is milder. If you must fertilize during summer, work with certified arborists to ensure you use the appropriate slow-release fertilizers. This provides a steady supply of nutrients without the risk of burning roots.
