Extreme Heat Plant Care: Keep Your Plants Healthy This Summer

When Virginia’s summer heat hits, your landscape can start feeling the pressure. High temperatures, strong sun, and inconsistent rainfall can take a toll on even the healthiest trees and plants. The good news? A few small adjustments can make a big difference in keeping your landscape thriving all season long.

1. Water Deeply, Not Frequently

Frequent, shallow watering can cause plants to develop weak surface roots. Instead, water deeply and less often — allowing moisture to reach the root zone.

Early morning watering is best, giving plants time to absorb moisture before the day’s heat sets in.

2. Add a Layer of Mulch

Mulch is one of the simplest and most effective ways to protect your soil. A 2–3 inch layer helps retain moisture, regulate temperature, and prevent roots from drying out. Plus, it adds a clean, finished look to your beds.

Pro tip: Avoid piling mulch directly against trunks or stems — keep a few inches of space for air circulation.

3. Shade and Shelter Young Plants

New plantings and smaller shrubs are more vulnerable to heat stress. Temporary shade cloths, lattice, or even grouping container plants together can help reduce exposure during peak sun hours.

4. Watch for Signs of Stress

Wilting, scorched leaves, or yellowing foliage can signal heat stress or dehydration. If you spot these signs, check soil moisture and adjust watering.

It’s also a good idea to trim back dead or damaged growth to help your plant focus energy on healthy recovery.

5. Choose Heat-Tolerant Varieties

Planning ahead pays off. Many native and drought-tolerant plants — like hollies, oaks, ornamental grasses, and crape myrtles — thrive in Virginia’s climate and handle summer heat with ease.

At Watkins Nurseries, we grow and supply plant varieties that are built to withstand the region’s toughest conditions.
