Re: Eucomis seedlings advice needed
I would think that you would be able to treat them similarly to adult plant. If they were in my garden, I would give them some cold, but not full exposure in a pot. I'd make sure they were in the ground and mulched.
I have visited a local nursery that propagates eucomis in exposed fields year round. I wouldn't imagine he gets too many losses, since he's been doing it for years as a profitable business.
