Hay-Contaminated Lawn Renovation: Soil Testing, Premium Seed & Corn Gluten Strategy

When "Straw" Turns Out to Be Weedy Hay

A Painesville, OH homeowner's landscaper used hay (not straw) during fall seeding. Hay seeds + crabgrass + dandelions now dominate. Homeowner wants to know if they must tear out lawn again.

Expert's Multi-Part Answer (Long Island Gardener)

Initial Response: Landscapers exploited ignorance. "Weed & Feed" is marketing poison—destroys soil, creates chemical dependency, risks health (pets, kids, mowing exposure). Demand refund with photos.

Soil Testing First: Use USDA map to find local Cooperative Extension (Cornell in NY). Soil analysis reveals exact amendments needed for perfect grass.

Seed Selection: Buy premium seed from Seedland.com. Northeast: Kentucky bluegrass varieties. South of Mason-Dixon: warm-season grasses.

Follow-Up Answer: Yes, start from scratch. Till, remove debris, plant new grass. But WAIT for soil test results—no sense planting in weed-seedy soil. Mow carefully, fertilize on schedule, cultivate for weed control.

Corn Gluten Timing: Apply in spring as weeds germinate (pre-emergent). Breaks down to slow-release nitrogen all summer. DON'T apply while new grass is germinating—it inhibits all seeds.

Core Philosophy

Science-based lawn care: test soil, buy quality seed, build soil health, use corn gluten for pre-emergent weed control + fertilization. Avoid Roundup/Weed & Feed. Hold landscapers accountable.
