How to Fertilize Your Lawn in Spring
Apply spring lawn fertilizer when grass is actively growing, when soil temperature reaches 55°F for cool-season grasses or 65°F for warm-season grasses. Use a slow-release nitrogen fertilizer like 20-5-10 at 3-4 lbs per 1,000 sq ft. Apply with a broadcast spreader in two passes (half rate each direction) for even coverage. Water in within 24 hours. Avoid fertilizing too early when grass is still dormant.
