The National Weather Service has issued a freeze warning for my area for tonight, which means that temperatures may dip below freezing. It might freeze again tomorrow night.
Since the peach tree is blooming, I decided to cover it with some old sheets in the hope that this will mitigate a mild freeze. Warm air coming from the ground should collect under the sheet and provide a small temperature boost.
I’m not sure how sensitive peach flowers are to freezing temperatures, but I don’t want frost to kill the flowers that will turn into peaches.
