A Case for Planting Graded Stock
A field test was conducted in northeastern Virginia to determine the effect of size of planting stock on early survival on an average site in this part of the Piedmont. 1 Four grades of planting stock were field tested on the Dulles Airport planting project at Chantilly, Va. The species selected--loblolly pine, Virginia pine, and white pine-were chosen because these species are favored for forestation in the general area. The quality and size of the stock were average, and normal care was given to it from bed to field. The soils are clay loams with moderately good drainage. The site is supporting a stand of Kentucky bluegrass which had not been maintained for at least four summers before planting; it had been invaded by annual weeds, concentrations of blackberry plants, and scattered dewberry vines. The vegetative competition was sufficiently heavy to interfere considerably with the growth and vigor of the planted trees, especially those of small diameter less than four-thirty-seconds inch).
