Bigleaf Hydrangea

Light

Morning sun and afternoon shade. Full sun only in the North with plenty of water.

Water

Keep evenly moist. Wilting on a hot afternoon is normal; wilting in the morning means water.

Planting and soil

Plant in spring or fall in rich, moist, well-drained soil. For blue, add aluminum sulfate; for pink, garden lime.

Feeding

A slow-release shrub fertilizer in spring. Low phosphorus helps blue color.

Pruning

Remove dead stems in spring once buds break. Deadhead through summer to push new flowers.

Through the year

Leaves in spring. First flowers in early summer on old stems, then on new stems until frost.

If something's off

No flowers usually means fall pruning or too much shade. Leaf spot in wet summers is cosmetic. Toxic to pets if eaten.

The reblooming mophead.

The first bigleaf hydrangea bred to bloom on both old and new wood, so a hard winter or a bad pruning job doesn't cost you the summer. Big mopheads come blue in acidic soil and pink in alkaline soil.

Why we stock it: Bigleaf hydrangea flowers even in places where winter usually eats the buds.
