My exploding foamy squash vine |
Yesterday, I went to weed around the squash and saw that the vines near the soil looked like something out of a science fiction movie. The insides had turned into foam and burst from the confines of the vine walls. It was creepy, and I wondered what bacteria could do that. They were beautiful, and everything was growing well one day, and the next, it was like they'd dissolved into creepy foam.
I googled "squash vine foam" and discovered pictures that looked exactly like my squash: I had vine borers. According to the University of Minnesota's extension website page on Managing Vine Borers in Home Gardens, all of this destruction was caused by the nasty larvae of a kind of a funky looking clearwing moth. I knew nothing about this thing, so all the information below is from them. You should check out their full article for a more detailed explanation, and read more for my short one.
