Lewisia - Aussaat

[Martin Tversted]

Why all these problems with sowing Lewisias?
I use to sow them in the fall under cover outside. In February they are exposed to all the snow and rain they can get here and end February/early March they germinate. Some are slow germinators and will first germinate after two whole winters. But it works fine this way.

Du hast ja Recht. Und vor 10-15 Jahren hatte diese Methode auch noch Gültigkeit.
Deine Methode nützt mir aber nichts, wenn ich die Samen erst in Februar bekomme. Zudem ist bei der Winteraussaat Schnee erforderlich, den es bei uns fast nicht mehr gibt. Und bei Barfrost gehen die Samen ein. Das sind meine Erfahrungen.

The past two winters have given even milder climate in Denmark. With a minimum of -8C the past winter and almost no snow, Lewisias have germinated anyway.

However, there are differences betwin the species of how much cold they need. L rediviva can easily be sown in February while other species needs two winters. But still with these relatively mild temps.
