As Charleston rolls into peak summer—with soaring temps, relentless humidity, and sun that just doesn’t quit—our gardens can start to feel the stress. But with a few thoughtful strategies, you can help your plants not only survive, but thrive.
At Hyams Garden Center, we’re here to guide you through the hottest months with expert advice and the right tools to keep your landscape lush and resilient.
1. Water Deeply, Not Frequently
It’s tempting to water every day, but shallow watering leads to shallow roots. Instead, water deeply 2–3 times per week. This encourages roots to grow downward, where the soil stays cooler and moisture lasts longer. Early morning is best to reduce evaporation and fungal risk.
Hyams Tip: Install a soaker hose or drip irrigation system for consistent, targeted watering that saves time and water.
2. Mulch is Your Garden’s Best Friend
A 2–3 inch layer of mulch helps retain moisture, regulate soil temperature, and suppress weeds. Organic mulches like pine bark or pine straw are excellent choices in the Lowcountry.
Bonus: As it breaks down, mulch improves soil health—especially important in Charleston’s sandy soils.
3. Protect Young Trees & Shrubs
Newly planted trees and shrubs are especially vulnerable. Shield them with shade cloth during extreme heatwaves, and water at the root zone—not the leaves. Avoid pruning in high summer, as this can stress plants and expose tender growth to sun scorch.
4. Feed Strategically
Avoid high-nitrogen fertilizers during peak heat. Instead, choose slow-release or organic options that gently nourish without promoting tender, thirsty growth. For trees and shrubs, mid-to-late summer feeding with a balanced fertilizer can strengthen roots going into fall.
5. Mind the Pots and Containers
Potted plants dry out faster and heat up quickly. Group containers together in partial shade, and consider double-potting (placing the nursery pot inside a larger decorative one with insulation in between). Use a water-retaining soil mix for extra moisture control.
6. Stay Ahead of Pests & Stress
Heat-weakened plants are more vulnerable to insects and disease. Check regularly for signs of stress like wilting, leaf scorch, or discolored foliage. Bring a sample to Hyams and let our team help diagnose the issue and suggest safe, effective treatments.
Charleston summers may be intense, but your garden doesn’t have to suffer.
With the right care—and a little help from your friends at Hyams—your trees, shrubs, and blooms can beat the heat and keep your outdoor space looking vibrant all season long.
