Do you need to mulch in Egyptian (Walking) Onion Plants in the Winter?
This is the first fall I am trying Walking Onions and have some bulbs coming this fall, to be planted in raised beds and am wondering if I will need straw, mulch or other protection for these beds in the winter?

No, these are hardy all the way to zone 3! They will consider your winters quite warm compared to what they can survive.
