Getting a cutting from a hydrangea primarily involves using the right tools to collect and prepare the stem, and then planting it in a suitable growing medium like gritty compost.
Preparing for Hydrangea Cuttings
Before you begin, gather the necessary tools and materials. Proper preparation ensures a higher success rate for your new hydrangea plants.
Essential Tools & Materials
To successfully take hydrangea cuttings, you will need the following:
| Tool/Material | Purpose |
|---|---|
| Secateurs | For cleanly collecting material from hydrangea stems. |
| Sharp Knife | To trim each cutting precisely. |
| Gritty Compost | The ideal medium for propagation. |
| Small Pots | To house your newly planted cuttings. |
| Watering Can | For initial watering and ongoing moisture. |
Step-by-Step Guide to Taking Hydrangea Cuttings
Propagating hydrangeas from cuttings is a straightforward process once you understand the key steps.
-
Selecting the Right Stem:
Choose healthy, non-flowering stems from the current season's growth. Look for stems that are firm and not too soft or woody. An ideal cutting should be about 4-6 inches long with at least two sets of leaves. -
Making the Cut:
Using your secateurs, collect the desired material from the hydrangea stems. Make a clean cut just below a leaf node (the point where a leaf or branch grows from the stem). -
Preparing Your Cuttings:
With your sharp knife, trim each cutting. Remove the lower leaves from the bottom 1-2 inches of the stem, ensuring no leaves will be buried in the compost. If the remaining leaves are very large, you can cut them in half horizontally to reduce moisture loss. -
Potting Your Cuttings:
Due to its woody nature, it's not possible to propagate a hydrangea cutting in water. Instead, you'll need to insert them into a pot of gritty compost. Create a small hole in the compost with your finger or a pencil, insert the prepared cutting, and gently firm the compost around the base to ensure good contact. You can plant multiple cuttings in one pot, spacing them a few inches apart.
Why Gritty Compost is Key (Not Water)
As explicitly stated by gardening experts as of March 25, 2024, hydrangeas are known for their woody stems. This characteristic makes them unsuitable for propagation directly in water. The woody nature means they are less likely to develop roots in plain water and are prone to rotting. Gritty compost provides the necessary drainage and aeration while retaining enough moisture, creating the perfect environment for roots to form without becoming waterlogged.
Aftercare for Your New Hydrangea Cuttings
After potting, water the compost thoroughly. Place the pots in a warm spot with indirect light. Keep the compost consistently moist but not soggy. Roots typically begin to form within a few weeks to a couple of months. Once new growth appears, it indicates successful rooting, and the cuttings can be carefully transplanted into larger pots or their final garden location when they are well-established.
