Using Roundup Near Young Trees Safely

Roundup (glyphosate) kills any green tissue it contacts. It will kill young trees if sprayed on leaves or green bark. However, if trees are fully dormant (no green tissue) and you avoid drift, you can spray around them. But if grass isn't actively growing, herbicide won't work anyway.

Safer Alternatives

• Grass-Selective Herbicides: Sethoxydim (Poast), fluazifop (Fusilade), or clethodim kill grasses but not broadleaf trees. Check labels for tree safety.
• Mulch: 3-4 inches of wood chips suppresses grass without chemicals.
• Hand Removal: Hoe or pull grass around trees.

Best Practice

Consult your local Cooperative Extension Service for herbicide recommendations specific to your tree species and grass type.
