I’m so jealous! I planted 150 seeds on purpose and didn’t get any monsters 
. Let it grow! That’s incredible! I spent way too much time and money. Next year, I’m just going to smash pumpkins in the yard and let them do their thing!
Try burying as many vines as you can. If you want, you can also remove a few flowers and small pumpkins to direct more energy to the biggest ones.
