Weed Control in New Hydroseeded Lawns

Critical First Steps for New Lawn Weed Management

Before applying any herbicide to a 2-month-old hydroseeded lawn in Amherst, NY, two identifications are essential:

1. Grass species: Check original packaging or ask the contractor what seed mix was used. Different grasses tolerate different herbicides.
2. Weed species: Identify whether weeds are broadleaf, grassy, or sedges.

Professional Diagnosis Recommended

Take a representative sample (grass and weeds) to your County Extension Office. For Niagara County, contact CCE at 716-433-8839. They'll provide accurate identification and legal, effective treatment options.

Herbicide Selection Framework

Once you know your grass type and weed spectrum, look for:

• Post-emergent herbicides (for existing weeds)
• Products labeled for seed-propagated grasses (not vegetative types)
• Formulations targeting your specific weed categories (broadleaf vs. grassy)

Proper identification prevents lawn damage and ensures effective, legal weed control. The effort invested now pays dividends in a healthy, uniform lawn.
