| Acer platanoides Norway mapleCulture: Norway maples are very adaptable and easy to grow, transplanting readily and withstanding city conditions. For this reason it is widely planted, and consequently, sometimes overplanted. There are some disease problems with this species, including Verticillium wilt, which can be serious. Verticillium wilt is most likely to become a problem in heavy soils with frequent irrigation. It also has several insect problems, which increase as the use of this plant becomes more widespread. The Morton Arboretum has conducted several studies on the girdling root problems associated with Norway maple. Usage: There are mixed feelings regarding the use of this species in the landscape. It certainly is a good shade tree, and the lustrous dark green leaves make a striking impression, particularly when used as a backdrop for lighter foliage or flowers. On the other hand, it is overplanted in some areas and has a dense canopy and shallow roots that make turf culture difficult. It is most often planted as a street, landscape, and park tree. |
