Perhaps they're not being pollinated. I know where I am, I had no bees to speak of, so I went out in the mornings and hand pollinated the flowers that looked ready.

Anything else I can do?

Hand pollinate, attract pollinators to the garden. Very common question on this board.

I have a question about hand pollinating. I have a cuke bush, and I had several female flowers first and no males. Now I have some males, but they don't seem to have any pollen (that I can see). Also, once the female flower closes (even in early morning) is it too late to try to pollinate?

I'm also having similar issues with my zuke. I had two nice huge fruit that I harvested and two more that looked good (and I thought I had pollinated) but they just shriveled up. Now I don't see any more female flowers, just males.

I have the same issue, but it's not a pollination issue. I find that's the first thing that people say and don't go beyond it. This variety of cucumbers are all female flowers with no pollination required. I have two growing, beautiful, cucs and a dozen babies that aren't getting any bigger. Kinda feels like they don't have the energy to grow more than one. Any thoughts?

It is still a pollination issue. Gynoecious cucumbers grow nearly all female flowers. Some varieties have a ratio of about 70 percent female flowers to 30 percent male flowers while other varieties have no male flowers but require pollination from cultivars that produce male flowers.
