Tree selection and planting advice

The Morton Arboretum has developed two companion publications to provide current, scientifically based tree selection and planting advice. Selecting and Planting Trees (PDF) is the result of decades of research to consider when planting a tree, including planting site characteristics, purchasing a quality tree, planting the tree, and maintaining a newly planted tree. The Northern Illinois Tree Species List (PDF) describes species that grow well in the area and recommends best planting sites. This list emphasizes the importance of site characteristics and is a tool for broadening the diversity of our regional forest to promote resiliency.
