Fertilize Lawn

Cool-season grasses (fescue, bluegrass) benefit most from fall fertilization (September–November) and a light feeding in early spring. Warm-season grasses (bermuda, zoysia, St. Augustine) should be fertilized in late spring through summer. Use a slow-release granular fertilizer for most applications — it feeds steadily over 6–8 weeks and is less likely to burn the lawn. Follow the bag's rate instructions and calibrate your spreader. Apply in the morning or evening, not in intense heat. Water in after application. Have a soil test done every 2–3 years (inexpensive through your local cooperative extension) to fine-tune NPK and pH adjustments. Over-fertilizing causes surge growth, increased mowing, and runoff pollution.
