Extending the seasons

As a nature observer, I love watching the changing of seasons. The days are definitely getting shorter, the nocturnal symphony is getting quieter, and early signs of fall are signaled by changes in leaf color in tulip poplars, sassafras, and sourwood.

From a vegetable-gardening perspective, though, I'm a bit greedy (even though I'm planting fall crops in earnest now). Not content with the long (three seasons) that I have, I'm figuring that I need to put together the sturdy cedar cold frame that I ordered to replace a flimsy aluminum one I bought a few years ago.

If I was handy with tools, or my gardening companion was (and alas, he's not), I know I could make one myself. But I don't have power saws or fancy drills. My new cold frame, I'm sure, won't look like these high-end English made ones, but the pieces look very sturdy! My idea is to carry over spinach, lettuce, and tenderer salad greens that might otherwise be frosted in our Zone 7b (working on Zone 8) climate, and experiment holding some of them over cold weather (think Elliot Coleman's Four-Season Harvest), an inspirational book, to be sure.

And why don't we have more small greenhouses in the U.S. like this delightful one, in a rectory garden in Southern England?

Inexpensive (for a greenhouse), simple, and not too big.
