I tried growing my own pumpkins this year and it didn't work out, so I'm wondering where I went wrong. I grew two heirloom varieties - Rogues and Jack Be Littles. I didn't run into trouble until the fruit started growing. All of the fruit on my Jack Be Littles have busted and split before they could finish developing. The fruit on my Rogues seem to fall away from the vine before it's time. I'm going to try again next year, so I'd like to know how to improve.
