Diana; Any suggestions for Augie's tomatoes?
(A....Did you clean your tomato cages before using them this year?)
Root cuttings would be a good idea at this point. You have a relatively long growing season. I have 6 ‘volunteers’ that I know are NOT cherry-types that I’m going to pot up this week and move to the greenhouse to see if I can have tomatoes, along with my usual salad greens until into December this year. Ya never know! With two layers of cover from cold air, I just might be able to pull it off.
As far as the vines being ‘toast’ is it Blight? If there’s still some green to the leaves, give them a pray of Copper fungicide. Can’t hurt, might help!
