I have been having problems with my tomatos for several years and the reason may have been that the area I planted in was wetter than I realized. This year I started over with raised beds-(2x12's) with new soil, a combination of topsoil, compost and sweet peat. I mulched with a hay/straw mix and removed it last week when the weeds started to get out of hand and replaced it with 1-2 inches of store bought compost. I use drip hoses beneath the beds but my sprinklers do reach the garden and I time them so it is midmorning so the leaves can dry. I am fighting a recurring fungal problem, ascending yellowing of the leaves of many plants which I am removing as soon as I spot. Some plants are getting very bare, at least the lower part of them. What am I doing wrong??!!
