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!!
