We have a brand new Contorted Filbert and no experience in caring for one. I have found some information on the web, but I'm left a few questions. I have read that the sucker roots must be pruned in order to keep the the branches growing in their proper contorted formation. Can the suckers be pruned at any time throughout the season or do we need to wait until pruning season (which I gather to be late winter or before the sap starts flowing). I'd asppreciate any information and clarification of any misconceptions. Thanks! Lori D. Anderson
