when I did that last year, I had 3 in the stem that I pulled out. the other plants well, they produced a lot of squash already and I didnt catch it in time before it started wilting. I wish I had known that they overwinter in the soil or I would have pulled those bad boys OUT! so now I can the luxury of having them this year as well
normally they don't come up this way. we had an extra early and hot spring last year.
