Its happening already. I noticed it last night. Half of one of my zucchini plants is dying from those dang squash borers! I read somewhere you can cut the stalk, dig out the worm and then build dirt up to where the cut was made and the plant will continue to grow. If anyone has done this, can you give me a how-to? Especially how you know where to cut (how do you know where the borer resides??).
