The fringe benefits of a container garden: when the forecast calls for overnight lows approaching 32 degrees in mid-May, you can just move the garden inside for the night!

If you live in or around upper Westchester County, you may want to think about row covers, Wall o’ Water, hay cover, or maybe just convince the dogs to sleep out in the garden tonight!  I’ve often thought it would be an interesting experiment to heat a lot of good-sized rocks in a firepit for an hour or two and then spread them down the garden rows… I wonder if that would work? 

What strategies do you have for keeping the garden safe from a late season frost?
