|What is a good deciduous tree that will grow tall for shade, but doesn't have exposed roots in the lawn? I live in the Chicago area.|
|University of Illinois Extension suggests the following:|
Common Hackberry, Celtis occidentalis, tolerates a variety of soils, including alkaline soils, and is a very adaptable tree. Tilia cordata, littleleaf linden, also tolerates urban conditions and is another good choice for a shade tree. Likewise, ashes are adaptable trees. White ash, Fraxinus americana, tolerates poor soil drainage & grows fairly fast. Green ash (Fraxinus pennsylvanica) is also adaptable and fast growing but twigs may be somewhat messy.
Honey locust, Gleditsia triacanthos inermis, is another popular shade tree, with several cultivars available. These trees feature more of a filtered shade.
Of the oaks, Quercus rubra, Red Oak, is fast growing, easy to transplant, and tolerates urban conditions. White oak is slower and more difficult to transplant. Pin oak is very susceptible to chlorosis on high pH soils.
Hope one of these suggestions is just right for your landscape.
