Most winter crops don't mind the cold, but some are more tender than others. With the weatherman predicting teens at night and highs in the 30's for days on end, we got busy!
The tender plants are grouped together in several areas of the gardens. Armed with stakes, string and huge rolls of plastic, we covered everybody that needed protection and then shoveled dirt along the edges to tent them in. We got them all covered, but it was quite a task!
The greenhouse, however, is a WHOLE different story.....
Greenhouse temperatures must be monitored very closely as the temperature can swing wildly as outside temperatures drop or rise. Even when it is really cold out, the weak winter sun can still warm the interior of the greenhouse drastically. The optimum temperature range in a greenhouse is between 60 to 80 degrees. When it is cold out, the greenhouse is the place to be. It is warm and balmy...almost tropical!
Keeping the greenhouse warm while outside temperatures are cold creates issues with humidity which can be problematic for the plants. We recently purchased a de-humidifier to help us control the humidity levels.
As this is the first year we have ever had a greenhouse, we are please that everybody in the greenhouse seems happy.....
