The young plants of the hardy varieties are also sometimes quite sensitive to frost. The roots, which are still tender, cannot tolerate persistent moisture in any case. It makes sense to spend the winter in a frost-free and relatively dry environment. In this way, the sensitive plants can continue to be supplied with water according to their needs without having to worry about root rot. From April the strong young plants can then be planted outdoors.
