Well, I water the old fashion way, by hand. So I know it is getting the same amount as it's neighbors. I had been watering every day during the very hot spell, now that we've had a rain or two, and it's a bit cooler, I have been watering every other day. I'll experiment with the watering a bit and see if it changes. I haven't been bothered with blight. I think it may be because I rotate where I plant tomatoes, and that I also rotate where I plant my garden. I cover the unused area with tarp, and it gets mighty hot under that thing. I'm guessing it may distroy a lot of what ever causes blight. Thanks for the help.
