How Corn Gluten Works as a Natural Pre-Emergent

Corn gluten meal is a natural byproduct of corn processing that inhibits weed seed germination through a unique mechanism:

• Releases natural dipeptides that inhibit root formation in germinating weed seeds
• Prevents weed seeds from establishing roots after germination
• Works on seeds that have not yet germinated - must be applied BEFORE weeds sprout
• Does not affect established plants - safe to use around existing lawn grass, flowers, and shrubs
• Breaks down naturally in the soil, adding organic matter and nitrogen

Weeds Prevented

Jonathan Green Corn Gluten prevents over 25 common lawn and garden weeds including:

• Grassy Weeds: Crabgrass (large and smooth), foxtail, barnyard grass
• Broadleaf Weeds: Dandelions, chickweed, clover, purslane, lamb's quarters
• Other Common Weeds: Pigweed, velvetleaf, and many more annual weeds

Note: Works as a pre-emergent only - will not kill existing established weeds.

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

1. Calculate Coverage: Measure your lawn area; one bag covers up to 5,000 square feet
2. Timing: Apply in early spring before weeds germinate (March-early May)
3. Application: Use a broadcast or drop spreader for even coverage
4. Watering In: Water thoroughly after application to activate the corn gluten and move it into the soil
5. Dry Period: Allow soil to dry out for 2-3 days after watering in for best results
6. 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.

Tips for Best Results

• Apply BEFORE weeds germinate - this is a pre-emergent, not a post-emergent weed killer
• Water in thoroughly after application, then allow to dry
• Effectiveness improves with repeated annual applications as organic matter builds in soil
• Do not overseed or seed new grass within 4-6 weeks of application (corn gluten inhibits all seed germination)
• Combine with Jonathan Green's lawn care program for best overall results
