The interesting flowers - which are actually false flowers - come into their own wonderfully, especially in rock gardens. Although the high mountain plant is well hardy, it cannot tolerate too much moisture in the cold season.
How can I protect edelweiss in winter?
In order to overwinter edelweiss in the garden, no pruning is necessary. In spring, dead plant parts should be removed and fir branches should be used as protection in severe frosts. For edelweiss in a pot, an insulating coating and a polystyrene plate are recommended to protect the roots.
Overwintering edelweiss in the garden
You basically don't need to worry about planted edelweiss, because in many cases the plant will retreat into its underground rhizomes. Pruning is not necessary; only the dead parts of the plant should be removed in spring. In extreme frosts, you can cover the plant with fir or spruce branches to simulate its natural winter protection - a thick layer of snow.
Overwintering edelweiss in a pot
Overwintering an edelweiss in a pot, on the other hand, is not that easy, because it is important to protect the sensitive root network from freezing. So wrap the pot with an insulating film or fleece (€72.00 on Amazon), although a jute bag filled with leaves can also serve the purpose. The pot is also placed on a Styrofoam plate to keep out the cold from below.
Tips & Tricks
If possible, you should bury the pot with the edelweiss in the ground over the winter - that's where it is best protected.
