If you've been looking for an step-by-step, organic feeding program for your lawn, this kit is it. Unlike synthetic fertilizers that can harm soil life and cause rapid, disease-prone growth, these organic formulas nurture healthy growth and support the soil ecosystem. They're easy to apply, too. Just attach the pre-mixed bottle to your hose and spray. Includes liquid corn gluten fertilizer for spring and fall, and fish fertilizer for summer.
