Whilst crop rotation is important, it doesn't seem the whole answer. We have a raised bed, no dig garden, built on bedrock and layered last winter with manures, lucerne etc. So no prior soil, let alone where tomatoes had been. Despie using the preventative milk spray on first signs, wilt has taken out two plants already, which still had a light harvest, and is close to killing a third, though it's harvest continues well. More experienced gardeners (this is just my second year) have said it's inevitable in Sydney and just to hope for some harvest before the end of the plant. I'd appreciate any other tips. My Dad suggested a copper sulphate spray, but we garden organically.
