I have been reading in a book entitle "Solar Gardening (Growing Vegetables Year-Round the American Intensive Way)" by Poisson. It reminds me of "Four Season Harvest" by Coleman. I'm wondering how many of you use season extenders? I'm thinking of laying down some black woven DeWitt "Sunbelt", allowing the soil to warm, then planting various vegetables or transplants under cones with a few brick in them to temper the heat and overnight cooling. I also like to plant tomatoes with a gallon can placed around them. The can no doubt draws heat to the plant too. I already have some "Sunbelt" on hand from end of roll remments from another project, so I wouldn't have to buy any. http://www.dewittcompany.com/wovengc.html#sunbelt http://www.hydrosource.com/web_clp/931101/avg.html While I spoke of planting under cones, I am also thinking along the lines of Wall-O-Water too. Another product that extends the season even a little more than WOWs is Saylor Caps. Well I can't currently find a link to show them. A wire frame is placed around a plant. A plastic bag with some water in it is stabbed onto the top of the frame, then lowered around the frame. The bottom of the bag covers the top of the frame because it is stabbed onto projections of the frame. The sides of the bag form sides kind of like a WOW. Similiar principal, but the top is covered too, thus allowing a little extra jump on spring. Hm, maybe it would be easier to move south for the winter and back north for spring. Anyway, who uses what extenders?
