Hand Pollinating Squash

After dinner the other night, I went out to the giant tangled mound at the back of the garden to search for a female blossom that looked like it would be ready to open the next morning. I found one: Its a female blossom because you can see at the base of the flower the little bulge that is the ovary, which will grow into a squash if it gets pollinated. So I got out my yarn, mostly because I could not find any tape, and did this to it:

The reason for that is to keep the flower from opening before I am ready. It keeps any bees from contaminating it with unknown pollen before I can get to it with the pollen I want to use. Squash flowers only open in the morning and fade by noon. A squash flower is receptive to pollen for a few hours in the morning; after 11am it's pretty much over. That is the reason for all the fuss.

The female flower was on a vine with "type 3" of my Georgian Chestnut squash, and I want to self-pollinate it, so I went to look for a few likely male blossoms on the same vine, and selected this one:The male blossoms have no bulge in the stem. I tied it up too:

The flower petals will be blocked from unfurling in the morning until I untie them, but the binding does not stop the ripening process. The pollen will be ripe in the morning, and the female flower will be receptive. Nothing to do now but wait until morning.

So after a nice cup of coffee, at about 9:30 the next morning, I went outside to do the deed.

I located the female flower. Yes I was correct, it was ready to open, see how it changed overnight, petals trying to unfurl, color much oranger:
I went and found the male flower. Its petal tips were also straining against the yarn. I picked it, leaving a long stem for a "handle":

The weather that morning was cool, overcast and drizzling but not raining. There were not very many insect pollinators out and about, conditions ideal for conducting this procedure.

I untied the male flower, and stripped off the petals, careful not to knock any pollen off of the anther. This flower was definitely ready, pollen grains were clearly visible and falling off. I untied the female flower, inadvertently damaging the petal tips slightly, it sprung open as soon as the yarn was released. It was definitely ready too. I rubbed the anther of the male flower on the stigma of the female flower, trying to sort of paint the pollen on all 6 of the stigma's lobes.

Then I immediately tied the female blossom petals back closed, to keep bees from contaminating it with other pollen, as the flower would probably remain receptive for a few more hours.

And that's pretty much it. Now I'll just wait a few days to see if it "took". The blossom and yarn will fall off in a few days, so I'll have to be sure and mark this squash somehow, and let everybody know not to pick it-it's being saved for its seeds.
