How to Help Your Garden Survive the Summer Heat

Summer has officially turned up the heat! With this month bringing some of the hottest temperatures of the season so far, your plants may need a little extra care to stay healthy, hydrated, and thriving.

High temperatures, intense sunlight, and dry conditions can put stress on even the toughest plants. Whether you’re caring for a vegetable garden, flower beds, containers, or newly planted trees and shrubs, these tips can help your landscape beat the heat.

Water Smart — Not Just More

When temperatures rise, it’s tempting to water more often, but how and when you water matters just as much as how much water you give your plants.

The best time to water is early in the morning, when temperatures are cooler and water has time to soak into the soil before the heat of the day. If morning watering isn’t possible, evening watering is the next best option.

Focus on watering deeply and thoroughly rather than lightly sprinkling your plants. Deep watering encourages roots to grow farther into the soil, helping plants become more resilient during hot, dry weather.

Check Your Containers Daily

Container plants dry out much faster than plants growing in the ground. During extreme heat, some pots may need to be watered every day — especially smaller containers or plants placed in direct sun.

A quick way to check if your plant needs water is to stick your finger a few inches into the soil. If it feels dry, it’s time to water.

Don’t forget hanging baskets! These often need extra attention during heat waves because they have limited soil volume and are exposed to more airflow.

Add Mulch to Protect Plant Roots

A layer of mulch acts like insulation for your garden. It helps regulate soil temperature, keeps moisture from evaporating too quickly, and reduces stress on plant roots.

Adding 2–3 inches of mulch around trees, shrubs, and garden beds can make a big difference during the hottest days of summer. Just be sure not to pile mulch directly against plant stems or tree trunks.

Watch for Signs of Heat Stress

Plants can show several signs when they’re struggling with high temperatures, including:

• Wilting leaves
• Drooping stems
• Leaf scorch or brown edges
• Yellowing leaves
• Dry soil that pulls away from the edges of containers

Some plants naturally wilt slightly during the hottest part of the day and recover in the evening. If a plant is still wilted in the morning, it may need additional water or protection from intense afternoon sun.

Give Plants a Break From the Heat

Avoid major pruning, transplanting, or fertilizing during extreme heat if possible. These activities can add additional stress while plants are already working hard to survive hot conditions.

If you recently planted something new, keep a close eye on it. Newly planted trees, shrubs, and perennials have smaller root systems and require more consistent watering while they become established.

Protect Your Plants and Enjoy Your Garden

Hot summer weather can be challenging, but with a little extra care, your garden can continue looking beautiful all season long. A few minutes spent checking soil moisture, watering properly, and protecting roots can make a big difference.
