Hi, I just planted a couple of thousand of them, on my seed package, it says 90 to 110 days to maturity, every year we have an annual pumpkin patch, so in order for our plants not to rot before October season, in Arkansas, we have to wait until July to plant them, generally, the vines begin to die back when they are finished. I hope this helps.

Thanks. I just wasn't sure. I'll have to go back on my calendar and figure out what day I planted. Thanks again for the advice!
