40% poison ivy in English ivy: hand-pull (non-allergic person) wearing full protection. Or: paint glyphosate on poison ivy leaves only—avoids English ivy contact. Repeat as poison ivy releafs.
Soil amendment: apply Holly-tone (acidic organic fertilizer) to favor English ivy's preference. Poison ivy tolerates wider pH range but may decline with acidification.
Prevention: monitor edges—poison ivy encroaches from boundaries. Bird-dispersed seeds require ongoing vigilance.
Never burn poison ivy—smoke carries urushiol oil causing severe respiratory reaction.
