Grows well in most soils; avoid wet and poorly drained sites. Mulch is recommended in the landscape.
Blooms on new wood - cut back by about one-third its total height in early spring, just as the new growth begins to emerge on the stems. Smooth hydrangeas may be cut back harder, however, this prevents woody cells from developing, prohibiting the plant from achieving its maximum stem strength.
We recommend full sun for smooth hydrangeas in the cooler end of its hardiness range; afternoon shade is a good idea in warmer climates. The flower color of smooth hydrangeas is not influenced by soil chemistry. Makes an excellent cut flower, both cut and dried.
