I planted asparagus last year. I have shoots growing this year but all the shoots are surrounded by a green long leaf thing and I don't know if that's a weed or part of the plant. Should I remove all growth around each spear, or is that part of the asparagus plant? I can't seem to find any pictures to let me know what is appropriate to be growing around the spears.

I have been told to plant asparagus with potatoes and onions. How do I do this? Do all three veggies get planted together in the same bed? Or do I plant the onions and potatoes in a bed next to the asparagus?
You just grow them next to one another in separate beds.
We have 10 acres of asparagus and about 80% of it froze last night. I was told that it should be mowed down. There is a lot of it just coming up. Could you help me?
Yes, you can cut, or mow over, the plants to remove the cold damaged foliage. Your asparagus has a hardy root system, so if you got some cold kill, other shoots will soon sprout.
Planted asparagus in the early spring. Plants have sprouted with very thin fingering branches that are growing good. Should I snap off the sprouts or let them grow all summer and winter? I have snipped off some of them, at the top to taste them. When do I start adding more soil to the crowns? When do I start fertilizing?
Only cut asparagus plants in fall. Simply amend the soil every year with compost to fertilize. You can also add some more soil, if needed, during this time, along with mulch.
