Q.Can yesterday’s male zucchini flowers be used to hand pollinate today’s female flowers?
Yesterday I had 5 male zucchini flowers and no female flowers; today there are all female flowers with no pollinators. Some of yesterday’s male flowers have a bit of pollen on them and I wonder if it is still viable.

Yes, and you can keep this pollen for longer in the refrigerator. I have to do this all the time, as I usually only do one plant at a time indoors. You can either save the whole flower, or just clip the stamen out and keep that.
