How to Green Up Your Lawn Fast
For the fastest lawn green-up, apply a quick-release nitrogen fertilizer like ammonium sulfate (21-0-0) at 4-5 lbs per 1,000 sq ft and water immediately. You'll see results within 3-5 days. For a safer option, use iron sulfate (which greens without excessive growth) at 2 oz per gallon of water as a spray. Milorganite with iron gives gradual greening without burn risk. Always water thoroughly after application.
