Hydrangea care

Asked August 2, 2019, 4:01 PM EDT

I would like direction on whether I should deadhead the flowers on my hydrangea. I have not been able to identify the type. This past year I did not prune it, the old wood stayed dead and new wood bore the flowers. Any help identifying the variety would be helpful.

Hello,

This is a bigleaf hydrangea, Hydrangea macrophylla. You have the ‘mophead’ type. There are many cultivars of this type so telling which one is difficult.

Here are references telling about care and when to prune.

You may clip off flower heads anytime. Just clip above a pair of side buds so that stem will continue to produce leaves and flowers if it isn’t killed over winter. Some gardeners like to dry the flowers and use them in dried arrangements, or decorate in fall and winter, over the holidays. Hydrangea may bloom on old wood if you give it winter protection( second link, above).

Thank you for using our service.
