Fall Lawn Plan: Identify Weeds, Then Seed or Weed-and-Feed

Kansas City homeowner with dense clay, possible nutgrass or crabgrass, and failing Zoysia plugs needs a stepwise plan.

Step 1: Identify the Weed

Search Google Images for "nutgrass" and "crabgrass" to confirm. Nutgrass has triangular stems and tubers; crabgrass is low, spreading, with finger-like seed heads.

Step 2: Eradication Strategy

• Crabgrass/nutgrass: Both are summer annuals dying at frost. Dig now with a hoe, then seed.
• Weed-and-feed (broadleaf control only) won't stop grassy weeds. Use only if weeds are broadleaf (dandelion, clover).
• Pre-emergent: Apply Scott's Turf Builder with Halts early April next spring to block crabgrass/nutgrass seeds.

Seeding Now

Fall is best for Kentucky bluegrass, perennial ryegrass, fescue. Don't mix with Zoysia—it's a warm-season grass unsuited to Kansas City winters and won't spread aggressively.

Verticutting helps seed contact in clay but isn't mandatory if you rake well.
