High Heat & Tree Care: Protecting Your Trees in College Park

If you have trees on your property in College Park, they are likely feeling the stress of high temperatures. Extreme heat can cause significant harm to trees, leading to symptoms like wilting, leaf scorch, and premature leaf drop. To ensure your trees stay healthy during heatwaves, it’s essential to provide them with proper care and attention.

When to Water:
The best time to water your trees is either early in the morning or late in the evening. Avoid watering during the hottest part of the day, between 10 a.m. and 6 p.m., as the water can evaporate quickly and may not reach the roots effectively.

How Often to Water:
Mature trees typically need watering once a week, while younger, newly planted trees require watering at least twice a week during extreme heat. Provide about 25 gallons of water per week to each tree from early spring until the ground freezes in winter. During excessive heat, increase the frequency to twice weekly.

Water Deeply:
A common mistake is shallow watering, which only wets the top layer of soil. Instead, water your tree deeply, allowing the moisture to penetrate the soil and reach the root system. Deep watering encourages roots to grow deeper, making the tree more resilient.

Best Watering Method:
The most efficient way to water your tree is by applying water directly to the soil. You can use a hose at a slow trickle around the base of the tree, or opt for a soaker hose or drip irrigation system. These methods deliver water directly to the roots, reducing evaporation and ensuring the tree gets the moisture it needs. Tree watering bags, often used by landscapers, are also available for purchase and provide a slow, steady water supply to young trees.

What to Avoid:
During periods of high heat, avoid any activities that may stress your trees, such as pruning or digging under the canopy. These actions can weaken the tree and make it more susceptible to damage from the heat.
