Tell us what you have that you’re concerned about. Most Perennials are tough as nails. They might get a little nipped around the edges by the frost, but there’s still plenty of growing season to recover.
I’ve had it SNOW on perennials with no problems. This time of year, even if we get some cold nights and/or snow, the next day or so it’s all gone, anyway.
That’s a relief. We turned our ingrown pool into a flower garden. It looks like most survived the winter,out. I didn’t want the 29-degree weather to take them out.
