    How has your garden produced in all this heat?

    Hey Damon,
    I know this isn't the right place to post this, but I can't find the other right place, and I can't find your email address. I have been meaning to let you know something about tomatoes for awhile. I have heard from you, and from a few other folks in other and more eastern parts of the country, how it is a BIG NO-NO to splash water on your tomato plants, and you should only get the soil wet around your tomato plants, because if you get the leaves wet, your tomato plants are likely to catch a fungal disease.
    Well, like I said, I've been meaning to tell you, I have lived in the Southwest of the U.S. almost all my life, and I've been either hand watering and sprinkler watering tomatoes for quite a few years, and they never once have got a fungus. I splash my tomato leaves with impunity, with no worries of funguses.  Always have.
    So here's what I am thinking: It's a dry heat out here (California–both southern, and most of northern), so I'm guessing the lack of humidity sufficiently dries the tomato leaves. However, back east, and in the South where you are at, where it is more humid, that must be too much humidity for a tomato plant to be able to handle if it gets its leaves wet. I am betting that tomato plants in general are more native to the dry heat of northern mexico, right? that would explain why they are more easily stressed by higher humidity in the South and back east, although they do like the heat where ever they are, of course.
    Just FYI.

    Hey, David, thanks for the FYI. I think there is something to what you’re saying. The tomatoes I planted this year were Neptune tomatoes, a breed of associated with the University of Florida, specifically bred to handle hot, humid climates of the Gulf Coast states. This has been the only tomato I’ve grown with any success.

    Apparently fungal problems like late blight are airborne, and the outbreaks do seem regional. Combine the airborne blight with a humid climate, I’m guessing there are several factors a play. The advice given to me via a former agricultural extension agent was to drip irrigate, mulch, use a copper fungicide, and plant a disease resistance tomato variety. As with anything I like to encourage you to collect your own empirical data and make decisions on that data.

    Can I ask you this? I’ve been thinking of putting together a forum so that people can post messages like yours, and so that you guys can talk with each other. What do you think about that?

    Gorw’em big!
    Damon
