I just planted asparagus this year, about 3 weeks ago and they are starting to come up now, so before the ground freezes in about 10 - 12 weeks what do I do with the asparagus? Just let them grow and die off or cut off the shoots before the ground freezes? I understand I can't eat them the first year, is this right? But, then they probably won't amount to much anyways this year. Hope you can help, thanks Chris
