When you write "under a bulb frame" it makes me think of your >bulb frame as some >sort of cloche. What does it mean? If you want the total details on my bulb frames, please see the Timber Press/NARGS book "Rock Garden Design and Construction." Breve, it is an unheated cold frame, Sorry, I am just finishing up moving and my computer, while now very fast indeed, is not quite configured as I am used to. Also, no more bulb frames: I now have a bulb house, and all that needs to be finished is planting the spring crocuses and putting on the top layer of sand and some topdressing. I am very, very tired.
