OK, Jim, I'll bite. Tell us more about this protected cold frame.
What is it made of, how deeply do you set it in the ground, what is
the glazing? Internal height? Do you use insulation around the
outside? Gravel base? Shade cloth in summer? How do you anchor the
glazing in high winds, etc? I ran a commercial greenhouse for years,
and so have held off going anywhere close to that direction for the
past decade in my own garden, but having given in to the dark side
and admitting that I adore geophyte (by joining PBS), I am now
looking at how to grow those species that can't take zone 8 conditions.
Details, please.
Kathleen
