Snow Queen® Oakleaf Hydrangea thrives in well-drained, slightly acidic soil enriched with organic matter. Ensure it receives morning sun and afternoon shade to prevent leaf scorch. Water consistently, particularly during dry spells, to maintain soil moisture. Prune in late winter or early spring to remove dead wood and shape the plant, but avoid cutting back too much to preserve blooms. Fertilize in early spring with a balanced, slow-release fertilizer for optimal growth.
