Should you need more hydrangeas, without purchasing new plants, there is another option to consider, such as stem cuttings. This is a relatively easy approach, and the right time for stem cutting is usually late spring to early summer, as the plant is fresh and thriving. Select a non-blooming stem with 4 to 6 inches in length and cut below the leaf node. The next step involves removing the lower leaves and trimming the other leaves that remain, by cutting them in half, reducing moisture loss. Place your cuttings into a pot full of propagation mixture, which should be moist and well-draining. You will need to cover the cutting with a clear plastic bag, ensuring that humidity levels remain constant and the leaves do not touch the plastic bag. Ensure that your pot receives bright, indirect sunlight. For further gardening advice, Gardyna also provides some useful tips.
