Pumpkin Patch?

Question:I planted pumpkin seeds in my backyard. They are all growing perfect and there are probably 20 new little shoots. There are Jack-be-littles, Sugar pie, and Jack-O-Lantern pumpkins (those were the names on the seed packs!). For each Plant grown, how many pumpkins will grow on each plant if you water, fertilize, and keep well-pruned? Thank you! (also they won't be crowded as they get older...)

Answers:
You will get 1-2 pumpkins per stem. Remove the smaller one if you want bigger pumpkins. You probably wont get exactly what you planted because they will cross pollinate, but they should still be good. give them lots of water and manure for better size
