The Best Time and Method for Taking Hydrangea Cuttings

Hydrangeas are a beloved addition to any garden. They provide beautiful blooms and can add color to your outdoor space all year long. While many gardeners are familiar with hydrangea care, the propagation of these plants is a bit less known. In this article, we will walk you through the best time and method to take hydrangea cuttings. Understanding these processes will ensure you have a successful propagation journey.

When to Take Hydrangea Cuttings

The golden period for hydrangea cuttings is from the spring when the plant is beginning to leaf out until late summer when the leaves are still lush and green. This is the perfect time as hydrangeas are deciduous plants and need some time to develop roots before going dormant in winter. Propagating during this time frame ensures that your new plants will be well-established before the cold winter months.

Preparing Your Hydrangea Cuttings

To give your hydrangea cuttings the best chance to root, start with healthy plants that are free from pests such as aphids or any disease. You can propagate both blooming and non-blooming stems, but it's best to choose stems without flower buds if possible. For the best results, select 3-5 inch long, tender green stems. Cut just below a leaf node, ensuring each cutting has at least 3 sets of leaf nodes.

Next, trim all but the top two leaves (or four leaves if the top two are much smaller than average) from the stem using a clean, sharp pruner. Be very careful not to scratch or damage the main stem. For large leaf hydrangea varieties with leaves 3 inches across or larger, trimming the remaining two large leaves in half can help reduce stress on the cuttings. For smaller leaf hydrangeas, you can keep the leaves whole.

Using Rooting Hormone (Optional)

If you choose to use rooting hormone, simply dip the cuttings in water, shake off excess, and then coat the stems with rooting hormone in a dry zip-lock bag. Alternatively, if you don't use any rooting hormone, your cuttings will still root, although it may take a bit longer. The key to quick and effective rooting is ensuring that the cuttings are healthy and have the proper soil medium.

Creating the Ideal Propagation Environment

For optimal results, place the rooted cuttings in a propagation tray or pot filled with a soil-less mix. The mix should be composed of 50% peat moss and 50% horticultural perlite. Soak the peat moss in water for 30 minutes before use to ensure it is fully hydrate. This mix is both light and nutrient-free, which is crucial for preventing rot.

To secure the cuttings in the soil, use a stick or pencil to make a hole and drop each cutting in. Space them 1-2 inches apart to provide ample room for growth. The cuttings should be kept in a humid environment to encourage root development. Cover the tray or pot with plastic to create a mini-humid tent, allowing for some air circulation by keeping the plastic slightly open or using a propagator if available.

Conclusion

By following these steps, you can successfully take and grow hydrangea cuttings. Remember, the key lies in creating the right conditions for root development. Regularly check on your cuttings and ensure they receive the necessary care. In no time, you'll have a flourishing hydrangea garden.
