Could my soil be full of pathogen
the reason I ask is because every year I seem to get a blight on my tomatoes and sometimes peppers.
In my line of work I'll sometimes work long hours with only one day off a week. During that time my wife, who has zero knowledge of gardening and doesn't care to learn, will water them overhead, with a hose, in the evening. Even though I tell her not to do it that way. (I think she hates me but that's for a different message board).
I also use the same tomatoe cages that are made of heavy wire mesh used for concrete slabs. I never clean them up before/after the season with say bleach our other chemical. I just remove all dead debris after the growing season. They are rusty.
I also water with a soaker house, under newspaper with old straw/hay that's been well seasoned.
Also, just on the other side of my fence my neighbor has two apple trees that are sickly, a sweet gum tree that's in decline and a dead box elder maple tree. I've offered to remove the trees, for free, but she won't do it. Why I don't know.
Now, I can only rotate my crops so much because of the size of my garden ( 24'x7' ). I'm pretty much married to this site for now.
Bottom line, how can I test my soil to find out if it's healthy or not? How can I cure it if it's sick? How can I get my wife to water correctly without using a shock collar?
Thanks for reading, I hope you guys can help.
