The hardy carnation needs protection from too much moisture rather than being protected from low temperatures. However, special care is not necessary. However, balcony plants are sensitive to frost.
How to protect and overwinter carnations in winter?
To protect carnations in winter, bedding plants primarily need protection from moisture, but container and balcony plants need protection from frost. Wrap planters in blankets, place them on Styrofoam sheets or overwinter them in a frost-free greenhouse.
Protect your planters from all sides from freezing temperatures by wrapping an old blanket around the container and/or placing it on a thick Styrofoam plate (€45.00 at Amazon). Alternatively, overwinter your carnation in a greenhouse where temperatures do not drop far below freezing.
The most important things in brief:
- Protection only required in the bed in extreme frost
- Protection against excessive moisture is usually more important than frost protection
- Container and balcony plants need winter protection
- Protect planters from frost from below (old blanket or thick polystyrene plate)
- Alternative: Overwintering in an unheated greenhouse (frost-free or low frost)
Tip
Carnations in balcony boxes need winter protection or suitable winter quarters, while bedding plants primarily need protection from excessive moisture.
