cutting back asparagus

I have asparagus. Some are 2 year old and some this was the first year all grown from nice roots. I could have harvested a lot more this year but I wanted the plants to really get big and strong. My question is, I’m in zone 7 and most of my plants are brownish green. Should I cut them down and should I put some hay for a nice winter covering? Also, should I put plastic over the hay? Please, any help would be grateful. I have put a lot of time and work into my asparagus. WHAT SHOULD I DO? THANKS.

When the plants turn brown, you can cut them back to the ground. You can then add 4 to 6 inches of mulch such as compost, leaves, pine needles, or straw, making sure any mulch you use isn’t full of weed seeds. Please see the last paragraph of this article:
