Hone in on Hydrangeas. Before you prune hydrangeas, you need to know which type you have. If you planted a hydrangea from our Hydrangea Guide, your answer is just a click away.

Take the quiz below to find out what type of hydrangea you have and when to prune.

Does your hydrangea bloom most of the season?

  • Yes? You have a new variety of hydrangea, such as an Endless Summer. If you’re planning on re-shaping, prune in fall after the final blooms. However, you can prune these at any time.

 Does your hydrangea have blooms in early summer that fade away by mid-summer?

  • Yes? You have a bigleaf, modheap, lacecap or oakleaf hydrangea that blooms on old wood. Prune these right as their flowers begin to fade to maximize next year’s blooms. Whatever you do, don’t prune in the late fall, or you’ll remove next year’s flower buds.
  • Pruning Old Wood Hydrangeas. Cut off any dead, diseased or deformed canes. Also, remove any branches that rub. Cut canes off close to the ground. If the hydrangea is older and has smaller blooms, remove up to 1/3 of the oldest canes. If the hydrangea is too tall, cut off the tallest canes.

If you want to keep hydrangea’s long-term health in mind, cut back canes to 18-24”. Also, prune canes to 18-24” if you’ve noticed your hydrangea flops to the ground due to heavy blooms.

Do you have a climbing hydrangea that grows upward?

  • If yes, prune in late spring or early summer. Skip pruning during their first year, though.
  • Pruning Climbing Hydrangeas. When pruning, remove any dead, diseased or rubbing branches.

 P.S. You can still can deadhead hydrangeas at any point.
