Posted by Karen Murphy on Tuesday, May 19, 2009 6:00 PM ADTWe have a 20 yr old Black Walnut that we will be removing. It has killed the grass beneath it. We would like to plant a Flowering Crab in its place. Do you think we can plant immediately or should we wait a year or more? We will not be digging out the roots. Thank you.
