Permanent Weed Control in Gravel Driveway: Doesn't Exist

Extensive gravel driveway. Roundup works weeks, then weeds return. State uses lime on roads—can I? Fixed income, tired of weeding.

No Permanent Solution

Weed seeds blow in, wash in, drop from tires constantly. Bare ground (even gravel) gets colonized.

Sustainable Routine

1. Spray new weeds every 2–3 weeks (glyphosate or pelargonic acid).
2. Small, young weeds die fast; large ones need more chemical.
3. Keep a backpack sprayer handy; 15 min monthly.

Lime? No.

Lime raises pH but doesn't kill established weeds. Blows away, harms adjacent lawn.

Accept maintenance as the price of a clean driveway. It's manageable if frequent.
