Late Summer Lawn Care Tips for St. Charles Homeowners

Summer watering tips for St. Charles, Missouri residents!

Prep Now for a Lush, Green Fall Lawn

As we move through August here in St. Charles, Missouri, your lawn is feeling the heat — literally. Late summer brings hot, dry conditions that stress your grass, and what you do now will directly affect how your lawn looks in the fall.

Here are some expert lawn care tips to keep your yard healthy and prepare it for a strong comeback as cooler weather arrives.

1. Water Deep, Not Often

August heat can dry out your lawn quickly. Instead of watering every day, water deeply 2–3 times a week in the early morning (between 5–9 a.m.). This helps roots grow deeper and become more drought-resistant.

💧 Pro Tip: Your lawn needs about 1–1.5 inches of water per week, including rainfall.

2. Raise Your Mower Blades

Cool-season grasses like tall fescue and Kentucky bluegrass (common in our area) do better in heat when left a bit taller. Set your mower to 3.5–4 inches to provide shade for the soil and reduce stress.

🛠️ Bonus: Make sure your mower blades are sharp to prevent tearing grass, which can lead to disease.

3. Control Summer Weeds Carefully

Crabgrass and other summer weeds are thriving now. However, avoid using heavy-duty herbicides in the heat. Spot-treat weeds instead — it’s safer for your lawn and more effective this time of year.

4. Schedule Fall Aeration & Overseeding NOW

Late August through September is the perfect time to aerate and overseed your lawn in St. Charles. Aeration relieves soil compaction and allows nutrients and water to reach the roots. Overseeding fills in bare spots and improves your lawn’s thickness.
