this year I covered the plants with a tunnel frame and bird netting in the hopes that it might also keep out the parent moths. Unfortunately, I lifted off the tunnel to weed and didn't get it back on.
I noticed the tell-tail signs of the squash vine borers last week and one nice sized squash on my plants. I had hoped that I'd get enough time before the borers killed the plants for that one squash to completely ripen, but I don't think I'm going to. I noticed yesterday that the leaves of all of the squash are wilting and I'd say by the end of the week that the plants will be completely dead. :(
I plan to try squash one more year and use a light weight row cover to see if I can keep out the insects, but if I fail again next year I will be done planting squash... :(
For more information on squash vine borers, check out this National Gardening Association post and this post from the NDSU extension .
I hope you are getting happier news from your garden this week.
Happy Gardening! :)
