sunrise frost

October 30, 2011

friday brought the first real white blanket of frost to the farm — crunchy little ice crystals on pretty much everything. just after sunrise, the fields were glittering. i walked the fields in my pajamas and down jacket, eating half-frozen raspberries off the brambles and savoring the crisp sunny early morning air, before embarking on a busy day of preparing for our fall harvest festival.

by early afternoon temperatures reached the 50’s and most plants showed no sign of damage, but the kale i ate yesterday did taste especially sweet. when temperatures drop towards freezing kale and its relatives — notably cabbage and brussels sprouts — increase the sugar content of their leaves, an adaptation that helps them avoid frost damage by lowering the freezing point of the water contained in their cells.

it’s a beautiful, transitional time of year.
