After no significant frost this year, the Pacific Northwest is experiencing a sudden severe cold snap. My bulb collection is exposed to ambient temperature, though covered against moisture. Everything is now frozen solid. The temperature is not expected to rise above freezing for about five days. What I wonder is, once a plant in growth is frozen, does it matter how long it remains frozen? Almost all the plants in my bulb house have previously survived about 20 degrees F for three days. Is five days going to be worse? Or do I just give up on all possibilities of survival because the plants were in unusually early growth? There are about 1,200 different species concerned. I did bring emerging seedlings into the garage before the freeze hit, but no protection was possible for the plunged pots in the bulb house. Any cover would have blown off in the present high winds -- the falling snow is whirling around as the wind gusts constantly shift. Explanations of hardy plant response to prolonged freezing welcome.
