Not all hydrangeas are reliably hardy and therefore need good protection against the cold.
Here you can find out how to overwinter hydrangeas in pots and beds.
Hydrangeas are now not only cultivated in the garden bed.
Many flower lovers like to keep the shrub in a bucket on the terrace or even as a houseplant.
Modern breeds are therefore no longer necessarily hardy.
These include above all the farmer's hydrangea (Hydrangea macrophylla) and the plate hydrangea (Hydrangea serrata).
Even old garden varieties of the subshrub are not 100% hardy.
On icy nights, the shoot tips and flowers threaten to freeze to death.
That's why hydrangeas, whether in pots or beds, should be given good protection against the cold in winter.
This is especially true in cold regions.
Otherwise, the flower threatens to fail completely next year.

Overwinter hydrangeas in pots
For hydrangeas in a bucket, wrap the pot in bubble wrap and a coconut mat.
Then cover the root area with a layer of foliage.
Protected in this way, place the hydrangea in a shady place on the wall of the house that is well shielded from wind and rain.
A windy location is generally not ideal for hydrangeas.
It is advisable to place the pot on a wooden or styrofoam board so that no cold can reach the root ball from below.
In the apartment, on the other hand, you should never overwinter potted hydrangeas.
"Hydrangeas need frost or at least cold to enter the important resting phase and to bloom profusely in the coming year," informs the
Plantura portal.

Overwintering hydrangeas in the bed
Even bedding hydrangeas need good winter protection in cold regions.
If you wish, prepare hydrangeas for the winter by July with a fertilizer rich in potassium - the mineral increases frost tolerance.
If it then slowly gets colder, a layer of leaves and brushwood protects the root area from the icy cold.
If there are very severe frosts in winter, you should also wrap the crown with a garden fleece, advises the
My Beautiful Garden portal.
This allows the hydrangea to hibernate well.
However, you should remove the winter protection again when the temperatures rise - for example after the ice saints - in order to avoid fungal infestation.
Incidentally, you should not cut off faded umbels of farmer's and plate hydrangeas in autumn.
The dried flowers also protect the inflorescences that have already been created from frost and snow.
Other hydrangeas, on the other hand, need pruning in the fall.
