How to Take a Cutting from a Hydrangea Plant

Taking cuttings is a cost-effective way to grow new hydrangea plants. It’s straightforward and requires minimal tools. Hydrangeas root easily from softwood or semi-ripe cuttings, making them perfect for home propagation. Timing, technique and aftercare are key to success, and with the right steps, you’ll have strong new plants ready to thrive in your garden.

When to Take a Cutting

The best time to take hydrangea cuttings is in late spring to early summer when the plant is actively growing. At this stage, stems are flexible but mature enough to root well. Avoid taking cuttings from flowering stems — non-flowering shoots are more likely to root successfully.

Step-by-Step Guide: Taking a Hydrangea Cutting

Step 1: Select a healthy stem
Choose a non-flowering shoot with strong, healthy growth. Look for one that’s firm but still green and flexible.

Step 2: Cut below a node
Using clean, sharp secateurs or scissors, cut just below a leaf node (where the leaf joins the stem). The cutting should be around 10–15cm long.

Step 3: Remove lower leaves
Strip off the bottom pair of leaves to expose the node — this is where roots will form. If the remaining leaves are large, cut them in half to reduce moisture loss.

Step 4: Prepare the cutting
Optionally dip the cut end in rooting hormone to encourage root development, though hydrangeas often root well without it.

Step 5: Plant the cutting
Insert the cutting into a small pot filled with a moist mix of compost and perlite or coarse sand for good drainage. Firm the mix around the stem to hold it upright.

Step 6: Cover and protect
Place a clear plastic bag or cloche over the pot to create a humid environment. Keep it out of direct sunlight, and open occasionally to allow airflow and prevent mould.

Step 7: Wait and water
Keep the mix damp but not soggy. Roots usually begin to form in 2 to 4 weeks. You’ll know it’s rooted when you see new leaf growth or feel resistance when gently tugging the stem.

Step 8: Pot on
Once well rooted, transplant the cutting into a larger pot or directly into the garden. Harden off outdoor plants by gradually exposing them to outdoor conditions over a week or two.

Tips for Success

• Take several cuttings at once to increase your chances.

• Avoid using stems that have flower buds — they’re less likely to root.

• Sterilise your tools before and after cutting to prevent disease.

• Keep the cuttings in a warm, bright location out of direct sun.

Choose the Right Type of Cutting

There are two types of cuttings you can take from hydrangeas:

Softwood cuttings (taken in late spring to early summer): These are young, flexible shoots. They root quickly but can be more delicate to handle.

Semi-ripe cuttings (taken in late summer): These are firmer and slightly woodier at the base. They take a little longer to root but are more resilient.

If you're new to propagation, softwood cuttings are usually easiest and fastest.

Don’t Let Cuttings Dry Out

Time matters — once you’ve cut the stem, try to get it into compost within 10–15 minutes. If there’s a delay, wrap the base in damp paper towel or place it in a sealed bag to stop it drying out. Hydrangea stems are especially prone to losing moisture quickly.

Label Your Cuttings

If you're taking cuttings from different varieties (say, pink, blue or white hydrangeas), label them as you go. It’s easy to forget which is which once they’re all potted up.

Use the Right Potting Mix

A mix of equal parts multi-purpose compost and perlite or vermiculite works well. You want drainage, but also some moisture retention. Soggy soil leads to rot, while too dry and roots can’t form.

Check for Root Development Without Pulling

Instead of tugging the cutting to check for roots (which can damage young growth), look for signs of new leaf growth — that usually means rooting has begun. If the cutting resists a light nudge, it’s another good sign.

Acclimatise New Plants Gradually

Once cuttings have rooted and you’re ready to move them outside, don’t just stick them straight into full sun or windy conditions. Harden them off over 7–10 days by placing them outdoors during the day and bringing them in at night. This helps avoid transplant shock.

Consider Using a Propagation Tray

If you're taking several cuttings at once, a propagation tray with a clear lid is ideal. It maintains humidity, keeps conditions stable, and makes it easy to check moisture levels across multiple plants.
