Dear Michael, here's the response to your question:

Hello Mike,

Thanks for reaching out to the UNH Extension Infoline. Pruning hydrangeas can be confusing, especially given all the different types!

Quick Fire is a panicle hydrangea, which is very common for both it's beautiful blooms as well as it's cold hardiness. It blooms on new growth so we recommend pruning this shrub in the dormant season- late winter to early spring (February to early April) before bud break.

UNH Extension has a handy fact sheet on pruning hydrangeas that I suggest you have a look at. For the most readable version, download it by clicking on the blue "Download Resource" button near the top of the article. It will open in a new browser tab.
