The panicle hydrangeas, like limelights, bobos, quickfires, etc, form their buds on the NEW growth each year (new “wood”). Pruning in spring stimulates new growth and protects the plants from extreme temperatures in the winter if you prune them in the fall, though they tend to be very hardy. They’re also nice to look at over the winter and they can provide some habitat for birds.
If you need to prune them this fall because they will be in the way over the winter or you are worried about snow or ice damaging or breaking branches, try to make sure it’s late in the fall when temperatures are consistently under 32 degrees fahrenheit (0 celsius).
You can maintain these as large shrubs or even multi-trunk trees. Keeping them small is hard because new stems can grow up to 3 or 4 feet in one season. When you do prune, remove all weak, broken and crossing branches, as well as any headed down toward the ground. This will help with drooping. Toward the end of the season they do tend to droop though, so don’t be alarmed if that happens.
Because of how big these can get, if you recently planted your panicle hydrangea too close to your house or driveway, walkway, etc.,, I would move it. I cannot emphasize this enough because I see this scenario constantly and it’s tough to manage.
