I've just got my onion sets for autumn planting and garlic which I'm
intending to plant out in the next couple of weeks.

Never done these before , so:

Do these need netting to protect against birds, as do spring planted bulbs?

Do I need to cover them with fleece overwinter? Somehow, I doubt if I
need to do this as they are supposed to be winter hardy.

I welcome advice from experienced growers.
