Plant Provence Lavender in well-draining soil with a pH of 6.5-7.5. Choose a sunny location with at least 6-8 hours of direct sunlight daily. Space plants 12-18 inches apart. Water deeply but infrequently, allowing soil to dry between waterings. Prune in early spring to encourage bushy growth. Avoid over-fertilizing; a light application of balanced fertilizer in spring is sufficient. Protect from harsh winter conditions with a breathable cover if necessary.
