Softneck garlic reverting to hardneck?
Both of my softneck garlic varieties have grown well with our unusually mild winter and warm spring. On a few bulbs I have noticed a knot in the stalk about 4 or 5 inches above the bulb. I thought it was a possible injury site that had healed and kept growing. After harvesting the garlic and curing it I noticed that the knots have grown so I split one of the stalks. It turns out it is a short scape. There are 4 to 6 bulbils on each of the ones that have done this. It is from softneck varieties that I have grown for a few years and have never had this happen before.
Is this something garlic does when grown in a warmer than usual year or could it be a possible mutation?
