Hi Marsh! I was wondering.. do you ever solarize your soil? If you do, how long do you leave your plastic on? I've always left my plastic on for 6-8 weeks but I wonder if the 8 weeks is really necessary. Also, I just read an article that said in soil solarization the soil is heated to a 18 inch depth but I wonder if that's true. Is it? Thank you for sharing you knowledge with us. :)
Here's the article on soil solarization that mentions how deep the soil is actually heated.
