December 20, 2010
A recent blog published on Deeproot Urban Landscape looked at the depth of roots for several different types of trees. They compared several different research papers to debunk a common myth about tree roots. This group was interested in learning the answer to this question because they are focused on the improving green infrastructure through street trees. As a home owner or landscape designer the study does have several relevant implications.
The study looked at 5 different tree species (Black Walnut, White Oak, Sugar Maple, Dogwood, and Eastern Red Cedar) in 2 different types of soils.
Lesson Learned:
The deeper the roots the more drought resistant a tree is. So be careful when planting a drought resistant tree because we know that they will grow deep roots.
