Pumpkin pollination update

So a couple of days ago the female flower opened one morning.  I only had a few hours to hand pollinate with pollen from a male flower. 

Then later that afternoon after pollination the flower naturally closed and started to die back.

So about a week later the little pumpkin went from pea sized, to marble, then a conker… and today it is a tennis ball!  Appropriate for Wimbledon week.
