Glyphosate Safety Around Palm Trees: Nursery Concerns

Florida palm nursery owner hears debate: some growers claim glyphosate (Roundup) stunts palm growth even without foliage contact. Asks for facts.

Science-Based Facts

Glyphosate is contact-only: no soil movement, no root uptake.
Kills only green tissue it touches.
Safe on mature, brown trunks.
Risk to young palms: Green, unhardened trunks can absorb herbicide, causing stunting.

Over-concentration causes damage. "More is better" is false. Follow label exactly. Shield young palm trunks during application.

No evidence of soil residual harm to established palms when used correctly.
