Another heat related question. I've been wondering about heat vs pollen viability and fruit set. I guess I'm wondering about the point at which pollen becomes useless. Somewhere on T-ville I read a while ago that pollination can occur within unopened buds, so I've been buzzing unopened flower buds to see if fruit set will result early enough in the life of the pollen before hot weather messes it up.
No definitive results yet as I hadn't marked which unopened flower clusters were buzzed. Duh. I will now going forward when the next hot streak comes in. There will be plenty of that in July.
Any thoughts?
