i gave them their chance, but since I found an un/under-pollinated aborted femaleKakai squash blossom, I decided to go ahead and hand pollinate them myself.
There were actually THREE female blossoms open this morning. ...and side-benefit of hand pollinating is that since the petals of the male blossoms need to be removed to get them out of the way, they can go in the harvest basket. I had them in my lunch salad.
Since Kakai is a C. pepo and susceptible to SVB (squash vine borer) I want them to set and develop their fruits as quickly as possible and hopefully to fully mature squash (and seeds -- Kakai is grown for their Hulless seeds) before they are taken down by the nasty buggers.
My summer squash (also C. pepo) and Guatemalan Blue (C. maxima -- and also susceptible) as well as a volunteer C. maxima are also starting to bloom. In fact I think the volunteer maxima has a female blossom that has set fruit, but I think I will hand pollinate whenever I see female blossoms.
I'm growing two varieties of C. moschata -- Black Futsu and Tromboncino, and a gourd eaten like summer squash as a trial -- Narcissus F1. These will hopefully be resistant and won't need to be coddled as much.
