This has never happened to me before, I actually thought a pesky squirrel had buried something in my window box! So I 'dug it up' and whooops, there went my vine.
Something doing much better than the now-dead sweet potato vine is our mums. They are STUNNING this year!
They are around three feet across, big balls of gorgeous. They started as $5 Home Depot specials two years ago. I had planted four, and only these two came back.My mom is dying of jealousy, she can't get any mums to come back and I don't do anything special to these! No purposeful watering, no fertilizer, no winter protection, no pinching back, nothing.
