If you’re in the Jackson area that seems colder on nights like this, bring planters back to the garage tonight. Cover the vegetables in the garden. Flowers planted around the foundation of your home can be fine with a few degrees of heat near the home. I would still cover what you can’t afford to replant. At Ann Arbor I would cover what you can easily cover or if you are feeling in a low lying, cold area.

Is this the last frosty night? With milder temperatures for the next two weeks, another frost would be hard to imagine.
