Hi Daniella, Well, my established ones just sit in the garage for the winter and come back every spring and bloom nicely......it gets down to a low of maybe 40F in there on really cold nights here in zone 6. If they are a standard hybrid they are generally tough as nails so you should have no problem. best of luck :o) Dan

Thanks Dan..do you water them at all over the winter while in the garage, like a cup or so every 4-6 weeks or let them stay dry? Is it an attached garage?

Hi Daniella, Mine get no water at all, but again, they are well-established by the time they go in the garage the first time for the winter so the soil will stay barely damp for a couple of months in all likelihood because they are in large pots with no leaves. My species from South Africa and Madagascar are in the basement (more tender) in small pots and get no water at all and are bone-dry, but that is normal for where they live. The garage is attached which is why it never gets below freezing. Best of luck with yours :o)

I did just get in a really rare Crinum acaule from South Africa and I will keep it growing through the winter because as far as it is concerned it is the start of summer and I want to make sure it thrives after being shipped around the world at considerable expense :o) Dan

Congrats on the new rare Crinum! I hope to see pix when she blooms for ya!
thank you for all the info, I really appreciate it..I will see what happens with mine, if its starts showing some growth, I will keep it going this winter.
