Light: While this is the most shade-tolerant type of hydrangea, it still needs some sun to produce flowers and get lovely fall color. All day dappled light or at least 4 hours of morning sun should be sufficient. For gardens at the cooler end of the hardiness range, it will thrive in full sun. For gardens at the warmer end of the range, it benefits from placement in afternoon shade.
Soil: Prefers moist soil that drains easily. Any period of extended sogginess will not be tolerated. Soil pH does not affect flower color.
Water: Average water needs.
Fertilizing: Nothing special required. If desired, you may apply a granular fertilizer formulated for flowering woody plants in late winter/early spring when the soil is workable.
Pruning: Pruning is not generally recommended. Flower buds are formed on old wood, so any cuts will likely remove flowering potential. Dead or damaged wood can be removed at any time, just cut back to a set of leaves. If you’d like to prune to shape the plant, this can be done when the plant is starting to break dormancy in early spring or late winter.
Other: Looks its best when established in the landscape, so trust that the awkward habit it may have in its nursery pot will transform into beauty.
