As I read my planting books, I get the impression that when the night time weather gets to 40 degrees Fahrenheit (or 4 degrees C) it’s safe to plant outside. For some days it’s been looking as if that day might end up being March 6. But as of this morning, that hope seems to fade. This is what weather.com looked this morning for someone in my area code.
An interesting look at planting dates in a nearby region is here. Just note that Texas tends to be warmer than northwest Georgia, which is in the foothills of the Appalachians. Another look at planting dates is provided by the online Mother Earth site.
