Don) Endl., Quercus lobata Née, Quercus agrifolia Née, Lagerstroemia indica L. ‘Watermelon Red’, Ginkgo biloba L., Platanus racemosa Nutt., Fraxinus iatifolia Benth. and Populus euamericana cv. Giacometti). In general, plants grown in treeshelters were taller and some had reduced caliper growth. Treeshelters reduced top dry mass of F. Iatifolia, P. racemosa, Q. agrifolia, Q. lobata and P. euamericana and also reduced root dry mass, root:shoot ratio, total root length and total root area for all species/cultivars except Q. agrifolia. The results are explained on the basis of the microenvironment in/ around treeshelters, photosynthetic partitioning and immobilization of plants growing in shelters. Management challenges and potential usefulness of treeshelters in landscape transplanting are also discussed.
