🌱 How to Care for Black Elder to Prevent Spider Mites?

💧 How to Water

Water young plants regularly (approximately every 7 days) for the first year until established. Once mature, Black Elder tolerates short dry spells but performs best with consistent moisture, especially during flowering and fruiting periods. Avoid waterlogged conditions.

☀️ Lighting

Black Elder thrives in full sun to partial shade. Full sun (6+ hours daily) is preferred for maximum flowering and berry production. In very hot climates, light afternoon shade can protect against heat stress. Avoid deep shade, which reduces flowering and weakens the plant.

🪴 Ideal Soil

Amend poor soils with compost before planting. Good drainage is important, though it tolerates moderately wet conditions better than most shrubs.
