Apply a slow-release synthetic fertilizer in late spring

What to Do

Choose a slow-release granular fertilizer (look for "slow-release" or "controlled-release" on the label) and apply at the bag rate in late spring, typically late May for cool-season lawns.

Why It Works

Slow-release nitrogen feeds the lawn steadily over 6-8 weeks rather than delivering a quick burst that causes surge growth. Products like Scotts Turf Builder (32-0-4) deliver concentrated nitrogen efficiently. Synthetic fertilizers show visible results within 3-7 days and cost roughly $3-4 per 1,000 sq ft per application.

Tips

• Avoid quick-release nitrogen in spring — it promotes excessive shoot growth and increases disease risk.
• Virginia Tech warns against high spring nitrogen rates that emphasize shoots over roots.
