Plant the Pee Wee Oakleaf Hydrangea in well-drained, slightly acidic soil with partial to full sun exposure. Space plants 3-4 feet apart. Water regularly, especially during dry spells, to keep the soil consistently moist but not waterlogged. Fertilize in early spring with a balanced, slow-release fertilizer. Prune after flowering to maintain shape and remove dead or damaged wood. Protect from harsh winter winds.
