These hydrangeas bloom on both old and new wood. Pruning is generally not needed, but they may be trimmed lightly after the early bloom. Bloom color can be shifted to blue with the addition of aluminum sulfate to the soil. Best in moist, well-drained soils. Supplemental moisture may be needed in very hot or dry conditions. Fertilize in spring with a controlled release fertilizer.
The Let’s Dance® series of hydrangea blooms every year, even after harsh winters! Reblooming Let's Dance hydrangeas bloom on both old and new wood, so even if the flower buds are damaged overwinter they will bloom on later season growth. H. macrophylla: Lower pH (5.0-5.5) will induce bluer flowers.
