Weed Control in a Moss Lawn Without Harming the Moss

A shaded, moss-covered yard in Northeast Georgia is a beautiful, low-maintenance alternative to grass—but weeds still invade. The challenge: eliminate weeds without killing the moss.

Spot-Treat with Glyphosate

1. Use a spray bottle with ready-to-use Roundup (glyphosate).
2. Shield moss with a piece of cardboard while spraying weed foliage.
3. Apply on a calm day; let dry completely (glyphosate is inactive once dry).
4. Weeds die in days; moss remains unharmed.

Create Conditions That Favor Moss, Not Weeds

• Compact soil – Don't till, fertilize, or add organic matter.
• Water lightly and frequently – Mist several times daily in summer. Moss loves constant surface moisture; weeds and grass prefer deep, infrequent watering.
• Don't lime – Moss prefers acidic soil (pH 5.0–5.5).
• Remove debris – Keep leaves and twigs off the moss mat.

Long-Term Weed Suppression

Once weeds are gone, the dense moss carpet naturally prevents new seedlings. Occasional hand-pulling or spot-spraying keeps it pristine.

Embrace the moss—it's a resilient, eco-friendly groundcover for deep shade.
