They claiming 23 here tonight. Maybe the wind will keep blowing and not let it frost. I rem several yrs ago a april frost killed all the acorns in north ga.
I wouldn't consider this a "late" freeze. I'm pushing fifty, and I never remember a year without hard freezes now. It was 17 here this morning, but the oaks haven't bloomed yet here, and won't for a few more weeks. Also keep in mind that while white oaks produce acorns on this year's blooms, the red oak group will produce this year's acorns on last year's blooms.
