With the “Endless Summer” hydrangea, unlike other farmer’s hydrangeas, the risk of flower failure is significantly lower. After all, this variety blooms not only on last year's wood, but also on fresh wood. However, the otherwise lush blooms can be significantly reduced by frost damage.
How to overwinter the “Endless Summer” hydrangea?
In order to overwinter the “Endless Summer” hydrangea successfully, you should protect it with a pile of leaves, a wire mesh frame with a mixture of leaves and straw, or a fleece or raffia cover. Potted hydrangeas are best overwintered frost-free in a cool, bright room.
Mulching the planted hydrangea “Endless Summer”
The farmer's hydrangea “Endless Summer” is actually a variety with quite good characteristics in terms of winter hardiness. Nevertheless, the flowers of this plant, which is actually very willing to bloom, can be endangered by winter frosts, which is why you must protect it by taking appropriate measures. The ideal solution is to pile up leaves, where you build a frame made of wire mesh (€15.00 on Amazon) around the plant and fill it with a dry mixture of leaves and straw. Alternatively, a fleece or raffia cover protects the sensitive buds. Frozen shoots are simply cut away in spring.
Tips & Tricks
In contrast to planted specimens, potted hydrangeas are better not to overwinter outdoors, but rather frost-free. A cool and bright room is ideal for this, although you shouldn't forget to water regularly, even in winter.
