Planting and Care Guide

Planting Tips

Plant in moist, well-drained soil. Space 4–6 feet apart. Water thoroughly after planting and mulch 2–3 inches deep.

Care Tips

Water deeply and consistently throughout the season. Blooms on new wood- cut back to 12–18 inches from the ground in late winter or early spring. Fertilize in spring with a balanced slow-release fertilizer. Incrediball® is famous for producing truly enormous, ball-shaped, pure white flower heads- some of the largest of any smooth hydrangea. The extra-strong stems are specifically bred to hold these massive flower balls upright even in rain. Flowers age gracefully to parchment in fall. Largely pest-free.
