  1. I would like permission to use the drawing of yellow nutsedge for an article I am writing for the Yard and Garden news, an enewsletter in Minnesota. Would this be ok? I can send you a link to the article, Many thanks, Mary Meyer

  2. This article is very helpful! Been trying to identify the stuff in my garden area for a while. The photo and description says it all!! Never had a problem til I had a truck-load of soil brought in, then the following year, this stuff started sprouting up all over! At least now I know what to do. BTW – I am in Southern Tennessee so we have hot summers and not so cold winters. This nutsedge is certainly a happy camper!! We WILL be putting an end to the campsite!! Thank you for your site and information!!
