Because we love zucchini, we planted another zucchini plant this year. It had three main stems and was producing lots of huge zucchini on each one. Then last week we noticed orange frass: the telltale signs of the Squash Vine Borer. (insert dramatic music here)
Yes, that damn SVB is back. We tried to poke holes in the affected stems and kill the larvae but the plant started wilting and we saw more frass. This sucks. Because the damage from the SVB was so near the root of the plant, the whole plant was about to go down. We ended up cutting off each of the three stems and sticking them into the ground. We did that last year and the plant grew; unfortunately, it was too late in the year to get an zucchini from it. We hope that at least one of the three former stems will bear zucchini before the summer is over.
We planted the zucchini in around the same place as we'd planted last year's zucchini so we're wondering if the SVB somehow overwintered in the soil and infested this year's plant. We're going to have to do some research on controlling and eradicating the SVB. I like zucchini and I want to grow it in our garden; the SVB, I can do without.
