Aw, man. I have vine borers. And they're in almost every plant. So, I've been out with the boning knife and the Sevin, having at 'em. The plants are still looking pretty good overall, but there is damage...guess now it's just keep hunting and see what happens.
I am intensely jealous of you guys with your healthy looking plants!
I feel your pain brother. I have lost at least 6 to vine borers, and I have about 6 trying to survive grub removal surgery. It looks like at least 2 or 3 are making a comeback. You might want to consider adding a spray also that you can target the underside of the leaves and the stems.
It is tough to look at some of the great pictures, but everyone in this thread has been so supportive of me that my jealousy is momentary. Plus, I still have about 4 plants that are now actually full fledged vines. Yeah!!
