A ridge site in the Appalachian Highlands of North Carolina was prepared for planting container-grown white pine seedlings by treatment with herbicide. A pellet formulation of picloram containing 10% acid equivalent was applied in May. Control of rhododendron, laurel and other hardwood vegetation was sufficient to allow pine establishment. White pine survival was 96% 18 months after planting. Inoculation of seedlings with a mycorrhizal fungus did not significantly affect seedling survival, total height, seasonal height growth, or basal diameter in the field. Height growth the second growing season after planting 6-month, container-grown stock averaged 5.1 to 7.5 inches. Eighteen months after planting, total seedling height averaged 13.3 inches, with the tallest exceeding 29.1 inches. Both height and diameter growth of white pine seedlings were inversely related to shading from remaining vegetation.
