That's interesting about the tops growing a bit in fall. I left onions out in the garden (bunching I think) and they had 6" tops. In the spring they were still green and now are growing again. So I wonder if I planted earlier this year (the garlic) and mulched. The ABG lady said to plant 2" down. I wonder if they grew a little in the fall if the greenery would survive to spring. The onions had what little snow we had to cover them plus were in a shady spot so kept that coverage through the ups and downs of frost this spring.
