I'm doing spring cleanup in my yard and have noticed that all of my society garlic has died in the center this winter. The outer ring of each clump is still alive but the inner portion of all six clumps that I have are dead. All of my society garlic was planted about six years ago. Is this normal due to the age of the plants?
This can be. I would wait until the growth slows down, or even now to divide them up, and remove the dead bulbs. Re plant the living bulbs, and give it fresh soil or compost. This should rejuvenate the plants.
