Q. How to Prune Bombshell Hydrangea

In the spring, I planted some Bombshell Hydrangeas. Throughout the summer they looked great. Now that the summer is almost over, most of the blooms have been spent and most of the remaining blooms are touching the ground. My thought was that I should remove the remaining blooms to allow for the new plants to focus growth on the foliage.   Also, does this type of Hydrangea grow off of old stems? Will hard pruning in the spring result in new growth?

It is actually recommended that you do minimal pruning with this hydrangea. They were bred so that they would not need any pruning, although in the spring you can clean it up a bit if you see some dead branches or for shaping purposes. Other than that, these hydrangea are good to go with pruning.

Q. Hydrangea care for winter

My hydrangea is called a Sugar Puff. It reads Hydrangea paniculata “Bombshell”. I live in the Midwest and would like to know if I have to trim this plant before winter, and any other care that it will need.

This variety does not need to be pruned in the fall, except that you can remove any dead branches. Hydrangea paniculata is winter hardy in zones 4 and above. If you are in a colder zone, you can protect yours from cold as described in this article:

Hydrangea paniculata varieties bloom on new wood and should be pruned in early spring before they begin growing again. This encourages growth of new wood, which will produce blooms. Follow the directions in the Hydrangea paniculata section in this article:
