How To Trim Hydrangeas

Hydrangeas are beautiful flowering plants that can add a pop of color to any garden or landscape. However, they can quickly become overgrown and messy if not properly trimmed. In this article, we’ll show you how to trim hydrangeas to keep them looking neat and healthy.

Why Trim Hydrangeas?

While hydrangeas don’t necessarily need to be trimmed, it’s a good idea to do so for several reasons. Trimming hydrangeas can:

  • Encourage new growth and blooms
  • Prevent the plant from becoming overgrown
  • Keep the plant looking neat and tidy
  • Help the plant maintain its shape and structure

When to Trim Hydrangeas

The best time to trim hydrangeas is in late winter or early spring, before new growth begins. This will give the plant plenty of time to recover and produce new growth and blooms throughout the growing season.

How to Trim Hydrangeas

When trimming hydrangeas, it’s important to use sharp, clean pruning shears to avoid damaging the plant. Here’s how to do it:

  1. Start by removing any dead, damaged, or diseased branches. Cut these branches back to where healthy growth begins.
  2. Next, remove any crossing or rubbing branches to prevent damage to the plant.
  3. Trim back any branches that are growing out of bounds or interfering with other plants or structures.
  4. If you want to reduce the size of the plant, cut back the branches by one-third to one-half. This will encourage new growth and help the plant maintain its shape.
  5. Finally, give the plant a light overall trimming to remove any straggly or overgrown branches.


Q: How much should I trim my hydrangeas?

A: It depends on what you’re trying to achieve. If you just want to tidy up the plant, a light trimming will do. If you want to reduce the size of the plant or encourage new growth, you can trim it back by one-third to one-half.

Q: Can I trim my hydrangeas in the summer?

A: It’s best to trim hydrangeas in late winter or early spring, before new growth begins. Trimming them in the summer could result in the plant not blooming the following year.

Q: What should I do if I accidentally trim off a flower bud?

A: Don’t worry! Hydrangeas are very forgiving plants, and they will likely produce new blooms later in the season.


Trimming hydrangeas is an important part of maintaining their health and appearance. By following these simple steps, you can keep your hydrangeas looking their best year after year. Remember to trim them in late winter or early spring, use sharp pruning shears, and only remove dead or overgrown branches. Happy gardening!
