For the last 12 years I have planted toms in the same spot of my 12' x 60' plot. 2/3's of my plot is planted with around 60 tomatoes and the rest of the space with hot peppers, beans and cukes. Now fighting blights of different kinds on my toms for the 3rd year in a row, I'm willing to try anything to have hope for a better 2012. I've done everything that Dave, Carolyn, Mulio and more have suggested here over the years, except crop rotation. Would it be worth a try to plant less toms and 'mirror' their location in the plot from year to year? Also, I'm now growing practically all heirloom varieties - maybe I should plant more hybrids?
