It’s that time of year again: killer frosts at night, cool days. Last week was mostly in the 70s (entirely global-warming freak-out bizarre) so I do have to tell myself that this weather, actually, is NORMAL. It is a bit of a change, though. Morning water-changing chores for the critters are, well, less pleasant.
The greenhouses’ contents are now snuggled under their rowcovers. I won’t take them off then until next March. The covers are really lightweight so most plants tolerate being draped with them. Double coverage like this is what actually makes the greenhouse successful. It tempers the shock of the nighttime temperature drop: if it’s, say, 20* outside the greenhouse, it will be 30* inside it and close to 40* under the covers. The next day, if it’s sunny: it will be 70* inside and 80* under the covers, even if it only hits the low 40s outside. A cloudy day won’t swing so wildly and actual ambient temperatures inside the greenhouse won’t be much different from what’s going on outside.
My only duty now in the greenhouses is to harvest. Luckily I never need to harvest a salad in the a.m.: the plants under cover look quite droopy and cold. By early afternoon they’ll have thawed and the water will be coursing through their cells, and by dinnertime they’ll be quite crisp and yummy.
