See the [Proven Winners Tuff Stuff page](https://www.provenwinners.com/plants/hydrangea/tuff-stuff-reblooming-mountain-hydrangea-hydrangea-serrata). ## Maintenance Plant in moist, well-drained soil; average water is usually sufficient, with extra moisture helpful during very hot weather. In hotter climates, afternoon shade is beneficial. Avoid routine pruning: remove dead wood in spring after new growth appears, and thin the oldest stems only as needed. NC State Extension notes that mountain hydrangeas bloom on previous-season stems, so light pruning protects flowering.
