Grass Invasion in Creeping Juniper & Mondo Grass: Spot-Treat with Glyphosate

Hand-weeding grass from groundcovers is a losing battle. Precision spot-treatment wins.

Paintbrush Glyphosate Method

1. Wear chemical-resistant gloves.
2. Pour glyphosate (Roundup) into a small disposable container.
3. Use a 1-inch artist's brush to paint ONLY the grass blades — avoid desirable foliage.
4. Apply on calm, dry day; no rain for 24 hours.
5. Grass yellows in 7–10 days; roots die.
6. Repeat as new patches appear.

Why This Works

• Glyphosate translocates to roots — kills the clump, not just tops.
• No spray drift = no collateral damage.
• Biodegrades in soil in ~24 hours.

Alternatives (Less Effective)

Sethoxydim (Grass-B-Gon) kills grasses only but requires spray — risky near broadleaf groundcovers. Pre-emergent (corn gluten) prevents new seeds but doesn't touch established grass.

Persistence with the brush wins. Your juniper and mondo grass will thank you.
