Jane You are a delight! Thank you for your replys. I recently purchased the book, which is on my winter reading list. I will be sure to obtain your article. The promised cool greenhouse is part of the reason we moved- to allow me more room and not to have to ask permission from neighbors. In truth the reason for not owning the greenhouse yet is that our former home has not sold yet and finances are a bit tighter than hoped for. To date I have been able to keep my bulbs warm enough with a layer of pine straw added right before cold nights and pulled away when the weather warms up. My more sensitive aloes, orchid cacti, orchids etc have required blankets. We only moved 5 miles from our home in town but temperatures in the country are much different. I can be scraping ice off my windshield in the morning when there isn't even a bit of frost on the grass in town. Perhaps a cold frame would be better for the bulbs- the moisture issue has concerned me. Our rains, when the come, can be quite dramatic in quantity. Also that might mitigate the problems I am presently having with bulb tags coming out of the pots when I move the straw aside. However, I am beginning to suspect that the true culprits there are my pets......This morning I discovered several little pots overturned and tags scattered, probably the result of a toad hunt by my cat with the help of my Italian Greyhound.
