Early on, my kabochas (and related squash, I always seem to have some other _weird_ looking squash in the patch), are loath to set because:
- There aren't any male flowers (with pollen)
- The bees haven't discovered the flowers yet
I almost always have about 10 days to 2 weeks of female flowers that preceed the males. If I see a male, I dab the stamin with a haiku brush and dab any female flowers I see. This results in setting. I generally do this for a few weeks until there are plenty of flowers, male and female, and bees to insure that pollination will occur naturally.
My questions are these:
- How much pollen is necessary to get the females to set? Are a few grains (or even a single grain) sufficient? I ask this because the first male flowers often have few if any pollen grains on them, so there's not much to go around.
- How long do the pollen grains stay viable? If I don't see another male flower for several days, are the grains still adhering to my haiku brush going to pollinate new female flowers effectively?
