Every year around this time I start to get an itch for some good ol'fashioned cold weather gardening. As the tomatoes and other warm weather crops fall by the wayside I tend to find myself wishing that fall and winter were more then just 'cleanup' season in the garden.
One of my first gardening books was Four Season Harvest by Eliot Coleman, and it is good enough to make any gardener start dreaming about coldframes, greenhouses and fresh salad all winter long. His other book, The New Organic Grower, is equally as good and I can't recommend it highly enough.
Maybe eventually I'll find some ways to work in some coldframes and the like, but until then I'll have to just keep on dreaming.
