“Say...any idea why our corn doesn’t have very many kernels?”
That’s poor pollination, either caused by the weather (too hot, too cool, too wet), or a lack-o-wind when it was needed.
Not much you can do about that at this point once the ears are developed. It has to happen at the right time; you can’t add extra pollen later.
You can give the corn stalk a good shake when the tassle (boy parts) and the silks (girl parts) are both ready to rock next time you grow corn, though. :)
(I know; it’s always about sex, sex, sex with us gardeners, LOL!)
Makes sense — thanks!
