What is different about growing a big pumpkin versus a small pumpkin?
First of all the seed you use is very different (basically big seeds grow big pumpkins and small seeds result in small pumpkins). Also, large pumpkins need more room to grow, 40 Sq. feet or more and small pumpkins can get along with 20 to 25 Sq. Feet. Lastly, very large pumpkins don’t like moisture stress (too little rain).
