My neighbor has a problem
My neighbor has a problem with his squash plants. Oddly, the plant leaves start turning brown around the edges and eventually die, but the squash keep producing nicely. Local agents mention "blight", but otherwise confess that they do not know the reason. Is it simply some sort of stress on the plants due to improper watering practices, or maybe soil problems, since it has been happening for the last two seasons? Should he even worry about it?
