Finally a female pumpkin blossom!
This forum has been so helpful! I worried that my pumpkin plants only had male blossoms but then I read on here to wait until the vines were longer. Sure enough, this morning when I did my daily check, I found my first female blossom! I hand-pollinated it with one of the many male blossoms. I'm so excited. I hope it is the first of many.
And on a related note, my zucchini had been producing lots of 3" zucchini that apparently weren't getting pollinated because they'd deflate and turn yellow. Thanks to this forum I started hand-pollinating (using a child's paintbrush) and now I have HUGE zucchini! Yippee!
