Renovating a "Wild Grass" Lawn: Complete Reset with Modern Turf Varieties

When "Lawn" Is Actually 5-Foot Tall Wild Grass

A homeowner moved into a house with 5-foot tall "grass" that regrows in 2 weeks after string-trimming. It's yellow with sparse green patches—clearly not turf grass but wild grasses.

Complete Renovation Protocol

1. Eradicate existing vegetation: Spray Roundup (avoid desirable plants), let die
2. Prepare seedbed: Rototill and rake smooth
3. Seed modern turf grass: 4–6 lbs/1000 sq ft of quality lawn seed blend
4. Establishment watering: Keep surface constantly damp (water 2× daily if needed) until germination. Light straw mulch helps (avoid wheat-straw with seeds).
5. Transition to deep watering: Once established, water infrequently but deeply (1 hr/week)
6. Ongoing maintenance: Mow weekly at 2.5–3.5 inches consistently

Key Distinction

Wild grasses grow tall naturally; turf grasses are bred for low, dense growth. No amount of mowing converts wild grass to lawn grass. Starting over with proper turf varieties is the only solution.

The expert acknowledges Roundup use here as a one-time reset for a hopeless situation, contrasting with typical anti-chemical stance.
