Planting Instructions

Spring or fall, space 3–6 feet. Test soil pH; add sulfur if needed to reach 5–6. Hole as deep as rootball, 2–3x wide. Poor soil: amend removed soil with little compost; else don't amend. Set plant, backfill halfway, water to settle, drain, finish backfill, water thoroughly.

Care

At least 1 inch rain/week. Mulch 2–4 inches organic to retain moisture, reduce weeds, stabilize soil temp. Feed monthly growing season with acidifying fertilizer. Prune early spring to shape; deadhead after flowering for more blooms. Check for whiteflies, mealybugs—control with horticultural oil/insecticidal soap. Marginally hardy regions: protect from hard freezes, drying winds.
