I had a terrible time with narcissus fly getting into my pots of cyrtanthus when they were outside last summer (2007), so this year I put them in a coldframe covered with a screen (window type). Thinking that the danger of fly infestation was passed, I took the screen off a couple of weeks ago, mainly because flower scapes were running into it. Did I take it off too soon? Or could I have removed it much earlier, and if so, when? The cyrtanthus really seem to have thrived in the screened environment, irrespective of whether it kept the flies off. It gave a little extra shade, and a bit of protection from the incessant thunderstorms we have been having this summer. Lots of bloom, even on the 'difficult' C. tuckii. --Roy Northwest of Boston 8" of rain in July!!
