Like many other plants, hydrangeas can be grown from seed. However, this is difficult and rather unusual. In this article you can read why this is so and how the offspring from hydrangea seeds can succeed.
Obtaining hydrangea seeds yourself is quite difficult
seed collection
If you want to get hydrangea seeds yourself, this is relatively difficult. The large flowers are sterile pseudo-flowers that do not produce seeds. The seeds themselves are very well hidden inside the plant. In addition, many new breeds no longer form any seeds at all.
The Sowing
The seed pods are tiny and have a diameter of about three millimeters. They contain the brown, spindle-shaped seeds. Depending on the hydrangea species, the seeds are equipped with small wings or are smooth at the ends.
Sow hydrangeas
Unlike in Germany, germinable hydrangea seeds are relatively often offered abroad.
Proceed as follows when growing:
- Fill small pots with potting soil.
- Scatter hydrangea seeds and cover with a very thin layer of soil.
- Mist with a sprayer to keep the seeds from washing away.
- To create a greenhouse climate, put a clear plastic bag over it.
- Air regularly to prevent rot.
It can take a relatively long time for the small seeds to sprout. As soon as they have reached a height of about ten centimetres, the small hydrangeas are pricked out. The tiny plants are still very sensitive and should be kept in a warm, sheltered place on the windowsill.
The first winter
The small hydrangeas also have to hibernate in the house for the first winter. Place the pots in a cool but frost-free place. The stairwell or a bright basement room is well suited. In the second year you can carefully accustom the Hydrangea plants grown from seed to the outside.
tips and tricks
Propagation of hydrangea by cuttings is easier and more promising. These can be cut from any plant, root well and quickly grow into strong plants.
