I never knew you could just leave it in the ground year after year, Kristi. I just assumed it would rot. Live and learn. I plant all mine from mid-October till early November, depending on when I have the garden cleared and have the time.
Generally, only the hardnecks form scapes and occasionally a softneck will. I had one softneck variety form scapes this year and I had never seen that before. I thought I had it mislabeled, but when I contacted a commercial grower, I was told that the variety often formed scapes. Not every variety of my hardneck will form scapes. Some varieties do consistently though.
