I live in a suburb of Chicago, IL. What is the best time of year to buy and plant a Tanyosho Pine?
Our volunteers who answer gardening questions live and garden in the mid-Atlantic. We are not able to provide advice to gardeners living outside of this region.
You are lucky to have two excellent sources for gardening information in your area:
Chicago Botanic Garden Plant Information Service.
Morton Arboretum Tree & Plant Advice.
They should be able to advise you.
