Safety & cautions

• PPE: gloves for thorns, milky sap, or skin-irritant species.
• Invasives: confirm legal status locally; dispose of seedheads in trash, not compost.
• Edibility: never taste a plant on appearance alone. Verify with multiple sources.
• Herbicide drift: avoid foraging near treated sites, roads, or contaminated soils.

Control cheatsheet

• Annuals: hoe or hand-pull before flowering; mulch bare soil.
• Perennials: dig crowns and rhizomes; repeat; smother with light-blocking mulch where appropriate.
• Seed prevention: deadhead or bag seedheads; clean tools and footwear after work sites with invasives.
