The first week of March we harvested our winter onions and started planting more seeds as well as cabbage and broccoli transplants. The next week the weather changed, as a winter storm was forecast to hit on the next weekend.
On the following Saturday we went to the garden and found the cabbage and broccoli plants for most part getting established with some signs of scorching from frost. We were concerned they would not be hardy enough to withstand the winter conditions in the forecast. We had not foreseen this possibility, and so didn't have any covers available to cover the beds.
So, we improvised by using plastic shopping bags to place over the individual plants, with dirt around the edges to prevent them from blowing away. During the next five days, we were hit with winter cold and strong winds that dropped the temps into the low 20s.
Fortunately our plants survived under the bags. After we took bags off, we experimented with some home made cloches made from plastic bottles and covers.
The next day the plants under them seemed okay, but we took them off as we were concerned they might get too hot under the strong sun as temperatures were climbing into the upper 50s.
Lesson learned: improvisation is okay, but preparation is better.
Cloches need close monitoring and work better for a back yard garden. We will need to get proper covers to have on hand for the beds.
