Sudden Tomato Plant Death
My tomato vines all have fruit on them and now they are starting to die, one by one. No bugs apparent, plenty of sunshine and, I think, enough water. They're in sand/clay but I put topsoil directly underneath them when I planted, and I just fertilized with 10/10/10. The vines are green, healthy looking with good sized fruit, but now they are starting to just shrivel up and die, one by one. Any answers or suggestions?
I think the problem might have been the wrong amount of fertilizer.
