Control of rhododendron by basal spray

Abstract

Rhododendron (Rhododendron maximum L.) is a large shrub that presents problems in timber management throughout the Appalachian Mountains. Although sometimes found in single clumps, rhododendron characteristically occurs in extensive dense thickets reaching heights of 10 feet or more (fig. 1). Of major concern to foresters is the difficulty in securing tree regeneration on areas occupied by this shrub. Also, because of its prolific growth, rhododendron undoubtedly competes severely with existing overstory trees for moisture and nutrients. Except where aesthetic values are a consideration, control or eradication is definitely desirable.
