How to take hydrangea cuttings

Expanding your hydrangea collection is a rewarding endeavor that doesn't have to break the bank. By learning the art of propagating through semi-ripe cuttings, you can transform existing plants into a new generation. Follow our practical guide to master this technique and propagate your hydrangeas for free.

Hydrangeas, known for their stunning blooms, can be successfully propagated from semi-ripe cuttings. This method involves taking cuttings during late summer when the plant's growth has matured enough to ensure successful rooting.

You can propagate various types of hydrangeas using this method, including mophead and lacecap varieties, Hydrangea paniculata, and climbing hydrangeas.

Timing Is Crucial Late summer is the prime period for taking hydrangea cuttings. At this time, the cuttings are semi-ripe – they display characteristics of both soft and woody growth. The base of the cutting has begun to develop a woody texture, which is essential for preventing rot when the cutting is placed in compost.

Steps to Take Hydrangea Cuttings

  1. STEP 1 Selecting the Right Material: Identify healthy shoots that haven't yet flowered, and are approximately 10-15cm in length. Ensure that each cutting possesses at least two sets of leaves beneath the uppermost set.

STEP 2 Preparing the Cutting: Trim the cutting just below a node – this is where leaves emerge from the stem. Trim away the lower sets of leaves by snipping as close to the stem as possible.

  1. STEP 3 Enhancing Water Efficiency: Halve each hydrangea leaf using a knife. This step reduces water loss and minimizes stress during the rooting process. Don't worry – these leaves will regrow once the cutting establishes roots.

  1. STEP 4 Planting the Cuttings: Individually insert the prepared cuttings into small pots containing gritty propagation compost. Firmly press them into the compost and give them an initial thorough watering.

  2. STEP 5 Root Development: Place the pots in a propagator to maintain optimal moisture levels during root development. It typically takes around six weeks for roots to form. Once rooted, you can transition them to a cold frame for overwintering.

  3. STEP 6 Potting On: With the arrival of spring and new growth, transfer the rooted cuttings to larger pots to encourage further development.

Remember, while hydrangeas might appear delicate, their hardiness allows for successful propagation. With the right techniques, you can watch your collection flourish and enjoy the satisfaction of nurturing new plants from existing ones.
