Not that many years ago, a April 8 "Easter freeze" had temperatures down to 22° in the Piedmont, so probably 5-8° lower in the mountains; it zapped natives and ornamentals alike.
But it is chilly, and we have forecasted lows of 27° for Saturday, nippy by whatever standards.
My cool-season veggies shouldn't be phased; the kale, spinach, carrots, beets, chard, lettuces, peas, mustards, arugula, etc. all are looking good, along with the garlic and leeks, which overwintered.
I just hope it rains tonight as predicted; we need it!
