What Is Old Wood?


Old wood refers to the branches on a hydrangea plant that have been around for more than a year. The age of wood influences the plant’s ability to flower. Certain hydrangea varieties, such as mophead and lacecap, bloom on old wood, while others, such as oakleaf and panicle, bloom on new wood.

Identifying old wood is easy – it is darker in color and has a rougher texture than newer branches. When pruning hydrangeas that bloom on old wood, be careful not to cut off the old branches. Doing so would eliminate the possibility of the plant producing flowers, at least for that year.

Reminder: always check the specific care instructions for your hydrangea variety when pruning.
