Rodger, Your comments about attempting to reroot cyclamen in pure sand because it doesn't support the growth of fungi and bacteria are greatly appreciated. My response when I read this were "Now, why didn't I think of that?" I mean, I've been growing these little guys for 30 years, for pete's sake! I should know better... I've occasionally discovered a well-knawed cyclamen tuber (root weevil) and have been attempting to save them by using a mix that's heavily weighted with 1/4 10. From now on, I'll use sand. And dust with sulfur. I've occasionally been successful at rerooting, but it's usually the rarest ones I lose almost immediately. On the subject of hardiness of graecum - we've had two weeks of temps hovering at lows between 18 and 22. My graecums in the rock garden have very darkened leaves, with tubers planted at surface level in old dune (sort of loamy sand), so I'm keeping my fingers crossed. I've never had survival issues in poly houses with reemay covering and temps down to 12, so we'll see. We've had little rainfall so that should help.
