years ago. likely weather and growing medium

I have gotten blight or other fungal problems with tomatoes at times.
I gave up on rotation planting, as that did not seem to solve the
problem. I think weather is a big contributing factor with my
disorders, none of them too serious. I also grow in large tubs on the
deck, where there is no crowding. That doesn't eliminate the problems,
either, but I have never had huge losses.

Fungus with nightshades is a result of wet leaves over night. When
needed water in the AM and not the plant, water the ground only...
tomatoes are best watered with buried soaker hoses, never overhead
watering. Tomatoes also benefit from good aeration, do not crowd. I'm
fortunate in that my vegetable garden is situated alongside a small
natural spring, I plant tomatoes closest to the spring, I never need
to water as that ground is always ideally moist.
