Anyone know how many pumpkin seedlings (musquee de provence and/or queensland blue) you can put into a half wine barrel? I have a terraced hillside and I'm going to put the wine barrel on one level and the vines will grow up and out over the next level, so I don't have to do any terracing.

Space to grow and spread won't be a problem. Just wondering how many I can put into the wine barrel before the roots start competing.

Thanks,
