It all seems to be a roll of the dice, although I'm sure environmental factors come into play. On the first plant to flower this season, I had 2 males open, and then the next day, one female opened. It's perfectly normal for them to be out of sync at first, but eventually, they'll start putting out enough blossoms that pollination shouldn't be as much of a factor (provided you have enough pollinators moving around).

If you know you're going to lose the female blossoms anyway, you might want to snip them off with their baby squash attached on the morning they open and eat them. Then, even if they won't "make it", they'll still end up on your plate. ;)

I have no females on about eight plants of different varieties!

Do you have another variety of squash that has male flowers-hand pollinate with the other variety. It won't matter at all.

Maybe give them a bit more time is all you need?

I've been having the same problem. The early yellow straightneck was the worst female dominator. It's planted in a raised bed with in bed composting (from last winter). It grew at lightening speed and started bearing all female in just a few weeks of sowing. What I did was to hand pollinate the female for that plant, borrowing the male flower from the green zucchini.

The yellow squash did start its own male flower later, but still way outnumbered by the female flowers.

If you can't consume or give away 10 yellow squash a day, you may want to use up the baby female flower like spaghetina suggested. They're good either in salad, stir fry, or deep fried (the most common recipe with cheese filling and breadcrumb).

I have been known to take a male bloom off a plant days before a female will open, close it back up and put it into a baggy into the fridge. Then as I see females start to open I will use that one to make sure they will produce. I have kept males up to a week this way.
I have also used a q-tip to touch the male then touch a couple females and that seems to work.

That was a good idea. The garden center had no reason to say no and gained good will from a customer and you gained squash.

of course if they dont pollinate you have fresh squash blossoms to stuff and fry!

I’m having the same problem and need advice!

I advise patience...they will come in time. It also helps to have multiple plants.

Wisdom. Thx. I do have multiple plants but I’m a new gardener. 🤔
