Can you pollinate a zucchini with a cucumber? and vice versa?

Hi,

I'm growing some food indoors which means i have to manually pollinate my zucchini and cucumber. I'm familiar with this process and have done it before. My problem is I just realized I only started one each of zucchini and cucumber. I already know I will be regretting having both as they have such a large growing habit the indoor space is limited. Therefore I don't want to plant a second of both. I'm hoping they are related closely enough that I can pollinate them with each other. If not I will probably have to sacrifice one to make space for a second of the other.  

I suppose I could make an experiment of it, which would be interesting, but could also mean not getting a yield, which would be sad, indeed.

Thank you all for you expertise and input.

No, they are not related closely enough to pollinate one another. Some varieties are self-fertile, though I think.  Check the packet.

All varieties are self fertile, and female only varieties of both exist which makes it a lot easier as they don't require any pollination at all. the only issue with the squash may be that you might not have male and female flowers at the same time.

Oh dear. When I read the title of this post I pictured myself with a cucumber in my hand trying to pollinate a zucchini flower. Then I realized that this is WRONG on pretty much every level. I blame lack of socialization. And my sophmoric sense of humor.

Anyway, it's no business of mine what consenting vegetables do in the privacy of their own garden.

Thank you all for the responses. I will leave the plants as they are and hope for the best with getting both male and female flowers on the plants at the same time. "crossing my fingers"

If they don't end up with male and female flowers at the same time you should be able to collect and dry the pollen and use it when called for.  BTW, I'm loving your adventuresomeness Jackie!

Here's some pics of my growing system. Its a Tower Garden aeroponic growing system, put out by juice plus. Not the height of permaculture, but brings me a lot of joy and some fresh food year round in New Hampshire.

Last year when I was hand pollinating in my greenhouse, I labeled paintbrushes with each plant type and would just brush all of the flowers of each plant with it every time I was out there dealing with the plants. It worked just fine.
