Grow in average, dry to medium, well-drained, alkaline soil in full sun. English lavender can be difficult to grow in the zones 5 and lower area, primarily because of winter stresses and high summer humidity. Well-drained soils are required, particularly in winter. Root rot commonly attacks plants grown in poorly drained soils. Prefers a light, sandy soil with somewhat low fertility. Remove faded flowers to promote continued bloom. Prune to shape in spring after new leaves appear. Prune back to 8†in spring every 3 years to control plant size and to promote robust, new growth. High summer humidity in the zones 5 and lower area is not appreciated. To combat high humidity, consider using rock instead of organic mulch. English lavender has slightly better winter hardiness than lavandin (Lavandula x intermedia) for the zones 5 and lower area, but still may appreciate a sheltered location and winter protection.
