Hydrangea Pruning #507214

Asked December 01, 2018, 2:29 PM EST

How and when should this blue hyrdrangea be pruned? It hangs down too much now and in the growing season. There are small buds beneath the current blooms.

Clackamas County Oregon

Expert Response

Thank you for your question. Your hydrangea appears to be a H. macrophylla, and you can prune now, but may cut away some of next year’s blooms. New growrh can be either blooms or lateral stems. Here is an Extension article from OSU: https://extension.oregonstate.edu/gardening/flowers-shrubs-trees/general-care-hydrangeas and here is another more expansive resourse: https://ucanr.edu/datastoreFiles/268-86.pdf Hope these are helpful. Good luck!
