I tilled more of the patch today. Growth of the main vine on the 1789 plant has been super fast the last three days so I'm trying to stay ahead of it. I got done what I needed to today but about a third of the patch still needs to be tilled. That will be completed next week and the Dan Micro sprinkler system will go in at that time.
A few days ago the first female flower showed up on the 1451 plant. Very round pumpkin, like a bowling ball. No females have showed up on the 1789. I hope one shows up in the next four days.
