Permanent Weed Control for a Large Brushy Area

Simply covering weeds with crusher run (gravel) won't create a lasting weed-free surface. Seeds blow in, germinate on top, and roots penetrate. A layered approach is essential.

Effective Strategy

1. Spray existing vegetation with a systemic herbicide.
2. Lay 6-mil black plastic as a barrier (optional but helpful).
3. Cover with 8+ inches of shredded wood mulch (often free from tree services) or aggregate.
4. Spot-spray emerging weeds 3–4 times per year until the seed bank is depleted.

Why This Works

Thick mulch suppresses germination, while the plastic blocks persistent perennials. Ongoing vigilance reduces the problem each season.

Avoid "once-and-done" expectations; soil seed banks persist for years.
