A reduced root system and difficult site conditions often lead to drought stress, which is a common problem for plant health practitioners when transplanting trees in urban environments. Major objectives of this research: (1) quantify relationship between mycorrhizae and plant-water relations during the first two years following transplanting by carbon isotope analysis and measuring pre-dawn water potential and soil moisture content; (2) quantify overall plant health by measuring caliper, tree height and width, leaf size and color and shoot growth; (3) determine the susceptibility of trees to biotic and abiotic plant disorders when mycorrhizae are and are not incorporated at the time of planting; (4) compare treatment response between endomycorrhizae and ectomycorrhizae host species.
