Is it practical to offer any protection, it seems to be mainly outdoor tomatoes that succumb, those in greenhouses survive, right? What experience can we find to formulate a method of protection? How ramshackle a shelter equates to greenhouse protection. Is it hygeine thats important, not to transfer the spores on hands,cans & water supply. Given that its likely to come airborne in rain, is a simplepolythene tent going to work. Please advance your knowledge and experiences.
