Bigleaf hydrangeas are known for their large, showy blooms. They primarily bloom on old wood, which means their flower buds are set during the previous growing season.
Hydrangeas come in a variety of species, and each type has its own unique growth habits that dictate when and how they should be cut. Knowing the type of hydrangea you have is the first step in determining the right care routine.

Pruning at the wrong time can reduce the number of blooms or damage the plant.
Pruning removes dead or diseased branches, allowing the plant to channel its energy into producing new, healthy growth.
