I'm always on the lookout for ways to winter over more and
different greens.
Have you read Four-Season Harvest, by Eliot Coleman? Here is my
review in Amazon.com:
Eat fresh, home-grown vegetables year round? Eliminate canning and
freezing? Do this all at low cost? Eliot Coleman does, you can, too,
and here is the how. Coleman is a market gardener in Maine who may
eat better than Bill Gates. He shows that sunlight and wind
protection are more important that temperature--and, by the way, most
of the U.S. gets more winter sunlight than Coleman's place.
Inexpensive, unheated greenhouses that he calls tall tunnel houses--
some say hoop houses--and cold frames protect from wind and keep snow
off the veggies. Greenhouse comfort is more to benefit the gardener.
The key is what and when to plant. Full info given for planting
dates, construction details, sources of seeds, tools, greenhouses.
Well illustrated. An essential guide for organic gourmands.
