Three-year height of green ash not affected by root and top pruning
Hardwood nursery stock is frequently root pruned and top pruned to facilitate planting. How severe a pruning various hardwood species will tolerate without detriment to survival and growth needs to be determined with consideration for the numerous types of planting sites being artifically regenerated. Briscoe (1969) reported that top pruned sycamore lost no ability to survive and grow when the tap root was trimmed to less than 4 inches and all laterals were removed. One year survival of green ash was unaffected by severe root and top pruning treatments even when summer rainfall amounted to less than 2 inches Woessner 1972).
