The little pumpkins, like you have, can be trellised. If you have a foot long vine just give it another foot or two and you'll see flowers. Once the flowers are pollinated, the fruit grows fairly guick. You'll love watching, from day to day, how much they grow. Being a small variety, these vines will grow, but you won't need a giant area if you were to grow them on the ground. I'm trying Atlantic Giants for the first time this year. I'm glad I have 4 acres to grow stuff!
