In this article, we'll cover when to cut back hydrangeas, how to prune different types of hydrangeas, the tools you'll need, what to do with the cuttings, common mistakes to avoid, and some frequently asked questions.

Why is it important to cut back hydrangea flowers?

Cutting back your hydrangea flowers not only helps maintain their overall health and appearance, but it also promotes more blooms in the future. If you don't prune them regularly, the bushes can become too dense and produce fewer flowers.

Is there a right time to cut them back?

Yes, the best time to cut back hydrangeas depends on the type of hydrangea you have. Some hydrangeas bloom on both old and new wood, while others only bloom on old wood. It's important to know which type you have before you start cutting.

When to cut back hydrangeas

Pruning Endless Summer and other reblooming hydrangeas

If you have Endless Summer or other reblooming hydrangeas, you can prune them lightly throughout the year as needed. They bloom on both old and new wood, so you don't have to worry about cutting off potential blooms.

Pruning mophead and lacecap hydrangeas

Mophead and lacecap hydrangeas should be pruned after they bloom in the summer. If you wait until the fall or spring, you risk cutting off potential blooms. Remove any dead or damaged wood, and cut back the stems by about one-third of their length.

Pruning smooth hydrangeas

Smooth hydrangeas should be pruned in the late winter or early spring, before new growth begins. Cut back the stems to about 12-18 inches above the ground, leaving a few buds on each stem. This will encourage new growth and more blooms.

How to prune different types of hydrangeas

The pruning technique you use depends on the type of hydrangea you have. It's important to know whether your hydrangea blooms on old or new wood before you start cutting.

Pruning Endless Summer and other reblooming hydrangeas

Since these hydrangeas bloom on both old and new wood, you can prune them as needed throughout the year. Remove any dead or damaged wood, and shape the bush as desired. If you want to encourage even more blooms, you can cut back the stems by about one-third in the late winter or early spring.

Pruning mophead and lacecap hydrangeas

Mophead and lacecap hydrangeas bloom on old wood, so it's important to prune them carefully. Wait until after they bloom in the summer, and then remove any dead or damaged wood. Cut back the stems by about one-third of their length, making sure not to cut below where the blooms were. This will promote new growth and a healthier bush.

Pruning smooth hydrangeas

Smooth hydrangeas bloom on new wood, so they should be pruned in the late winter or early spring before new growth begins. Cut back the stems to about 12-18 inches above the ground, leaving a few buds on each stem. This will promote new growth and more blooms.

Tools you need to prune hydrangeas

To ensure a clean, even cut and avoid damaging your plants, you'll need some basic pruning tools:

• Clean, sharp pruning shears
• Gloves
• Eye protection (especially if you wear glasses)

Using dull or dirty tools can make pruning more difficult and increase the risk of spreading diseases among plants.

What to do with the cuttings

Instead of throwing away your cuttings, there are a few ways you can use them for garden decor or composting:

• Place them in a vase or jar of water to create a simple yet beautiful flower arrangement.
• Use them as part of a larger floral arrangement for a special occasion.
• Dry them out and use them in wreaths or other seasonal decorations.
• Compost them to add nutrients to your soil.

Common mistakes to avoid when pruning hydrangeas

Here are some common mistakes people make when pruning hydrangeas, and how to avoid them:

Cutting them back too hard

If you cut your hydrangeas back too hard, you risk removing next year's blooms. It's better to prune lightly and wait until the following year to remove more if needed.

Pruning at the wrong time

Pruning at the wrong time can also result in fewer blooms. Make sure you know when your hydrangeas bloom and whether they bloom on old or new wood before you start cutting.

Not sterilizing your tools between cuts

Using the same tools on different plants can spread diseases and pests. Make sure you sterilize your tools between each cut using rubbing alcohol or a solution of water and bleach.

By following these tips, you'll be able to cut back your hydrangea flowers like a pro in no time! Remember to determine what type of hydrangea you have and when it blooms before pruning, use the right tools, avoid common mistakes, and don't waste your cuttings.
