Dual-Action Lawn Feeding Beyond weed prevention, corn gluten meal is a natural nitrogen fertilizer that: Contains approximately 9-10% nitrogen by weight Provides slow, gentle release of nitrogen to lawn grass Promotes deep, rich green color without excessive growth spurts Builds soil organic matter over time with repeated applications Supports beneficial soil microbial activity Application Timing - Critical for Success Timing is essential for effective pre-emergent weed control. Apply before weed seeds germinate: Primary Spring Application: March through early May - before soil temperatures reach 55°F (when crabgrass germinates) Soil Temperature Tip: Apply when forsythia is in bloom - a reliable natural indicator that crabgrass germination is imminent Late Spring Application: Late May for continued weed suppression Early Fall Application: September for fall weed prevention Late Fall Application: October-November for overwintering weed suppression Maximum Applications: Up to 4 times per year for improved weed control and greening How to Apply Calculate Coverage: Measure your lawn area; one bag covers up to 5,000 square feet Timing: Apply in early spring before weeds germinate (March-early May) Application: Use a broadcast or drop spreader for even coverage Watering In: Water thoroughly after application to activate the corn gluten and move it into the soil Dry Period: Allow soil to dry out for 2-3 days after watering in for best results Repeat: Reapply up to 4 times per year for maximum weed control and lawn feeding Safe for Children, Pets & the Environment Jonathan Green Corn Gluten is significantly safer than synthetic pre-emergent herbicides: Made from natural corn - a food-grade byproduct No synthetic herbicides or harsh chemicals Safe for children and pets to re-enter treated areas Better for the environment than conventional pre-emergent crabgrass preventers Breaks down naturally without leaving persistent chemical residues Supports soil health rather than depleting it Use in Flower Gardens & Planting Beds Unlike many pre-emergent herbicides, Jonathan Green Corn Gluten can be safely used in flower gardens and planting beds to prevent annual weed seeds from germinating around established plants - making it a versatile tool for the entire landscape.
