The most common method for propagating hydrangeas is propagation from cuttings. The cuttings can develop roots not only in potting soil, but also in a glass of water. Here we explain how you can do this.
How do you propagate hydrangeas in a glass of water?
To propagate hydrangeas in a glass of water, cut cuttings from the mother plant and place them in the water. If you keep the water low in lime and change it regularly, roots will form on the shoots within a very short time, which you can then plant.
Can hydrangea cuttings root in a glass of water?
The cuttings of hydrangeas can alsoin water begin to form roots. It is important to prevent the shoots and roots from starting to rot. If you choose a transparent glass, you can keep a clear view of the roots.
What do I have to pay attention to when I put cuttings in the water?
- The cuttings should be approximately 10 to 15 centimeters long and have no flowers or buds.
- Remove all or part of the leaves. Under no circumstances should leaves be left in water.
- Change the waterdaily to prevent rot.
- Fill the jar with filtered tap water or rainwater. The water must be low in lime, as hydrangeas do not tolerate lime well.
What is the advantage of propagation in water over soil?
The advantage of propagating cuttings in water compared to in soil is that you can keep an eye on the roots of the cutting at all times andwatch them grow. At the same time, you prevent the cutting from drying out in water. Roots usually form more quickly in water than in soil. This means that propagating cuttings in water is the fastest way to propagate hydrangeas, even compared to sinkers and cuttings.
Tip
Random propagation in the vase
If you put a bouquet of hydrangea flowers in a vase, it is not uncommon for them to start to take root there. If you plant the shoots in potting soil now, with a bit of luck new plants will emerge from them.
