Lesco / Anderson's Professional 24-0-6

Overview

Professional-grade slow-release fertilizer used by lawn care companies across the country. The 24-0-6 ratio provides high nitrogen for leaf growth with potassium for root strength and stress tolerance, with no phosphorus (which most established lawns don’t need).

How It Works

The slow-release nitrogen feeds gradually over 6-8 weeks, avoiding the surge-and-crash pattern of quick-release fertilizers. This produces steady, even growth without excessive clipping production.

Where to Buy

Available at SiteOne Landscape Supply locations, which are open to homeowners despite being primarily a professional supplier. Anderson’s branded versions with similar formulations are available online.
