This variety is the one if you want to grow a real monster. The current world record is over 1500lb. This variety will grow large pumpkins even without the attention that the experts give!
Sow the seed at the end of April and plant out in a well manured plot during May if you can protect from the cold. Otherwise plant out in June. The plant needs lots of water and regular feeding. When the flowers set chose one or two pumpkins to grow on if you are going for a big pumpkin.
