There is not always a sheltered corner on the balcony or terrace where the hydrangea can overwinter. In this case, the hydrangea must be moved indoors and cared for during the cold season in a frost-free and cool room. The cellar is very suitable for this.
How do you overwinter a hydrangea in the basement?
To overwinter hydrangea in the basement, place the plant in a frost-free room with a temperature of two to ten degrees. Ventilate daily, water moderately when the top inch of soil is dry, and slowly acclimate to daylight in spring.
Bring Hydrangea into the house in good time
The hydrangea's winter dormancy lasts from November to the end of March. Since many Hydrangea species form buds the previous year, potted plants should be put into winter storage before the first night frosts.
The optimal conditions in the cellar
The basement room for winter storage should ideally be two to ten degrees warm. Ventilate the room daily so that the humidity can escape and shoots and buds do not start to rot.
Don’t forget to water
Make sure that the soil in the flower pot does not dry out too much, clumping together and thereby suffocating the roots of the hydrangea. Water the plant moderately but regularly whenever the top centimeters feel dry.
Tips & Tricks
As soon as the hydrangea sprouts again in spring, you can give it more light. First place plants on the balcony or terrace for an hour at a time so that they slowly get used to the changed conditions.
