Effects of soil and air temperature on vegetables
I've just recently joined and recently started gardening so this is a rookie question. In an earlier post about gardening books I came across the following response by "okiedawn":
"It was this book that taught me about the effect of soil temps and air temps on plants, which may seem elementary, but most of us don't know those things when we're just starting out. Once you understand the effect of air and soil temps on your plants and their productivity, everything else just falls into place."
The book referenced was "The Vegetable Book" by Sam Cotner. I had no idea this was so important. Worse, that book is hard to find and expensive. Cheapest used one I've seen is $94.00. Can anyone recommend some resources that will enlighten me about this part of gardening, and how everything falls in place after it?
