Late‑Summer Lawn Rescue: 7 Must‑Do Tasks in August for a Healthier Yard
Essential Lawn Care Tips for Homeowners in Whatcom County Before Fall Arrives
As August rolls in, many homeowners notice their lawns struggling with summer heat, increased foot traffic, and uneven growth. Whatcom County’s unique climate means your grass needs extra care right now to stay lush and vibrant before fall arrives. Whether you’re managing a small residential yard or a larger property, following the right late-summer lawn care steps can make all the difference. In this guide, I’ll share 7 must-do tasks that will help your lawn bounce back, reduce stress, and prepare for the cooler months ahead.
Recommended fertilizers for late summer include:
- Slow-release nitrogen fertilizers: These provide a steady supply of nutrients over time, promoting steady growth without forcing the grass to grow too quickly.
- Balanced N-P-K formulas with micronutrients: Look for fertilizers with a balanced ratio (like 10-10-10 or 16-4-8) that include trace elements such as iron and magnesium to improve color and overall health.
- Organic or natural fertilizers: Products like compost teas, seaweed extracts, or products with humic acid help improve soil structure and support beneficial microbes.
Applying fertilizer during this period can help your lawn recover from summer stress and prepare it for fall growth and winter dormancy.

7 Essential Tasks to Revive Your Lawn Now
1. Water Deeply & Smart
Watering your lawn correctly is critical in August. Aim to give your grass about 1 inch of water per week, preferably early in the morning to reduce evaporation. Deep watering encourages roots to grow deeper, making your lawn more drought-resistant and healthy.
2. Mow High & Leave Clippings
Keep your mower blade set a bit higher during late summer—about 3 inches or more. Taller grass shades roots and holds moisture better. Leaving clippings on the lawn acts as a natural fertilizer, returning nutrients to the soil and saving you time on cleanup.
3. Limit Foot Traffic
Try to avoid heavy foot traffic on your lawn during hot or wet periods, as this can compact soil and damage grass blades. If certain areas are high-traffic zones, consider adding stepping stones or paths to protect your turf.
4. Hold Off on Heavy Fertilizing
Avoid applying heavy fertilizers during August, as this can stress your lawn further. If you need to feed your grass, opt for a gentle, slow-release fertilizer formulated for summer use to maintain steady growth without burning.
5. Monitor for Pests
August can bring about pests like chinch bugs or grubs that damage grass roots and blades. Keep an eye out for brown patches or thinning areas. Removing excessive thatch and using organic treatments like neem oil can help manage infestations naturally.
6. Clear Debris Regularly
Remove fallen leaves, sticks, and other debris promptly. This allows sunlight and air to reach the grass, preventing mold growth and keeping your lawn healthy.
7. Prepare for Fall Aeration
Late summer is the perfect time to test your soil for compaction. Use a screwdriver or soil probe—if it’s difficult to push in, your lawn may benefit from aeration in early fall. Aeration helps improve air, water, and nutrient flow to grass roots.
