Summer planting of container-grown northern hardwoods

Abstract

Seedlings of paper birch and yellow birch were grown in Styrofoam blocks of two cavity sizes, 40 cc and 125 cc, in four different soil mixes. After 16 weeks, the seedlings were outplanted on a cleared forest site in mid July. Seedling survival for all treatments after two growing seasons was very good (98.8 percent). The effects of container size and soil mix were relatively small and statistically significant only at the time of outplanting. Paper birch seedlings grew much more rapidly than the yellow birch. An early August outplanting of red maple seedlings was added to the study. Growth and survival of the red maple was similar to that of the birches.
