Abstract: Trees provide many benefits that can be realized atthe local level, but poor growing conditions in parking lots and other hardscape areas often result in premature tee death. Planting recommendations are not guarantees, but they inform us about the probability that a tree will survive and be in good condition. Pragmatically, planting recommen: dations are cost-benefit equations that must be solved for each projec. Recommendations to facilitate growing trees in parking lots remain largely untested. We evaluated 1,127 parking lat tees at Walt Disney World to determine planting success, examine the effet of soil volume on tree condition, and test the applicability of existing planting recommendations, The majority (81 percent) of Walt Disney World tres were in good condition, and only 3 percent had died since planting. Those that died, did so within twelve yeas of planting. All ofthe tres in at leas fifteen hundred cubic fet of soil were in good condition, and ‘Quercus virginiana planted in groups fared better than tres planted individually, Species-specific differences in the response of Walt Disnay World tees to planting conditions were evident. The existing planting recommendations were imperfectly applicable to Walt Disney World parking lot tees.
