Sigh.... The dreaded squash vine borer has attacked some of the winter squash. These nasty pests will bore into the stem of squash (they are particularly fond of hubbard types) and quickly wilt and kill the stems. This vine wilted overnight.
This is the same variety of squash next to the affected one. So far, it has not been hit. I am not holding my breath however.
Here is another vine, in the other garden, also affected. I did surgery on this vine, slitting the vine stem horizontally and physically removing the borer, which looks lkke a white grub, with a brown head. There is maybe still hope for this one.
