Keep Your Lawn Hydrated (But Not Drowning)
August heat can quickly stress grass, especially cool-season varieties like fescue or bluegrass. Water early in the morning to minimize evaporation and help roots absorb moisture. Aim for 1–1.5 inches of water per week, either from rainfall or irrigation. Overwatering can lead to shallow roots and fungal growth, so keep a balance.
Pro tip: If you’re planning sod installation, August can still work for warm-season grasses like Bermuda, zoysia, or St. Augustine — just ensure consistent watering until roots establish.
Control Weeds Before They Spread
Weeds like crabgrass and spurge thrive in hot weather. Pull them before they go to seed or apply a targeted post-emergent weed killer. By acting now, you’ll reduce the problem in the fall and next spring.
Mulch to Protect Plants
A fresh layer of mulch around trees, shrubs, and garden beds helps retain soil moisture, regulate temperature, and suppress weeds. In August’s heat, mulch can prevent your plants from baking in the sun and reduce the need for constant watering.
Prepare for Fall Planting
Believe it or not, August is the pre-game for fall landscaping. Start planning any projects like planting shrubs, trees, or perennials. Late August into September is one of the best times for planting because soil temperatures remain warm, but air temperatures begin to cool.
Keep an Eye on Pests and Disease
High humidity and warmth can bring an uptick in lawn fungus, grubs, and plant diseases. Check leaves for spots, lawns for brown patches, and soil for insect activity. Early treatment saves you from expensive repairs later.
Tidy Up and Trim
Lightly prune overgrown shrubs, remove dead or faded flowers, and edge walkways for a clean, defined look. Avoid heavy pruning of trees this month, as it can stress them in the heat.
Storm-Prep Your Landscape
In many areas, August means the risk of late-summer thunderstorms or hurricanes. Check that trees are healthy and remove weak limbs that could cause damage. Secure outdoor furniture and décor when severe weather is in the forecast.
Final Word
August landscaping is all about balance — protecting your plants from the summer heat while preparing for the cooler months ahead. By watering wisely, controlling weeds, mulching, monitoring pests, and planning for fall, you’ll keep your home’s curb appeal high and your outdoor spaces thriving.
