Establishment Rates for Different Bareroot Grades of Trees

Abstract

Establishment rates of eleven grades of bareroot green ash were compared at two locations for three growing seasons. Three whip and two branched grades consistently showed the greater percentage increases in trunk diameter than the other six grades. There were large differences in growth rates and survival between the two locations. In the clean-cultivated plots all trees survived and after three growing seasons 8'-branched and smaller grades had at least doubled in trunk diameter. Similar size trees planted at a different location in high grass and mulched with wood chips had poorer survival rates with no grades doubling in average trunk diameter.
