Mulch around a panicle hydrangea is the best winter protection
Gardeners can protect panicle hydrangeas with a 5-inch mulch layer, while winter-hardy cultivars like Hydrangea paniculata usually need no elaborate covering.
- Panicle hydrangeas, including Little Hottie, require a 5-inch layer of mulch for winter protection and are reliably winter-hardy in Zones 3 and 4, extending into Canada.
- Distinguishing hardy Hydrangea from less hardy species requires checking botanical names on plant tags. The Endless Summer series includes less hardy cultivars: Bloomstruck, Dream Cloud, Pop Star, Summer Crush, and Twist-n-Shout.
- Fencing is the best defense against rabbits, while repellents like Liquid Fence and Plantskydd deter deer. Wrapping with burlap on a frame prevents winter sun and wind damage to hydrangeas.
- Perennials are best planted directly into the ground rather than wintering inside a garage. The 16 arborvitaes planted at a lake cabin should be wrapped as temperatures gradually decline.
