Weed-Free Gravel Driveway: Switch to 3/4-Inch Crushed with Fines, Use Pre-Emergent

Upgrade the Gravel

Pea gravel rolls and never compacts. Replace with ¾-inch minus crushed stone (includes fines). It locks together like pavement but drains. Spread 4–6 inches, compact with plate compactor.

Weed Program

1. Apply granular pre-emergent (Preen or Casoron) in early spring and late summer.
2. Spot-spray vinegar (20%) on any breakthrough weeds on hot sunny days.
3. Accept a few weeds in the tire tracks—total eradication is unrealistic.

Why Not Plastic

Soil blows onto plastic, weeds grow on top, plastic degrades into brittle shards. Fabric is slightly better but still fails long-term.
