This morning it was 6 degrees when I woke up. That’s about 10 degrees below what I consider acceptable for our location and I mean to write a letter of complaint to the weather gods. It was the biggest challenge that the greenhouse has had to face. Last night as I was watching the greenhouse temperature dip to 36 degrees when the outside temperature had fallen to 11 degrees by 1am I put on my down jacket and carried another heater out to the greenhouse to stabilize the temperature. That seemed to do the trick because the max-min thermometer showed that was as low as the greenhouse temperature got last night. It never got above 16 degrees outside today and we’re headed for another single digit overnight so I just left the supplementary heater in place.
The greenhouse remains a place of refuge for weather like this. Another oxalis species has come into bloom.
and I even found a ladybug exploring the greenery last week.
I have no idea what these temperatures will mean for the outdoor plants. Some plants that I have put in have never seen temperatures this low. The evergreens are tightly wrapped up against the cold.
The Rhododendron carolinianum is one of the first to bloom but I think the plant certainly looks stressed at the moment. I’m particularly concerned about the camellias as this is certainly pushing the edge for some of them. Helleborus niger ‘HGC Jacob’ was looking great before the snowstorm last Thursday, but it’s pretty smashed and browned off at this point.
At the same time the Lathyrus aureus has popped above the ground and seems completely untroubled by the temperatures.
Perhaps I’ll have more promising whispers of spring this weekend when the temperatures are supposed to climb back to the 50′s.
