Managed Development of Tree Roots. II. Ultra-Deep Rootball and Root Barrier Effects on Southwestern Black Cherry    (View PDF)

Philip A. Barker

Abstract: Three-year-old seedlings of southwestern black cherry (Prunusserotinasubsp. wrensvar. virens with rootballs 35 and 70 cm deep were field planted in northern California in April 1986 to compare the effects on root development of rootballs of two depths and a root barrier, which was a polyethylene casing around the rootballs of half of the trees of each treatment. Three growing seasons later, the roots were excavated to a depth of 32 cm in an area within a radius of 1 m from the tree trunks and dry weights of the exposed roots of each tree determined. There was no significant difference in root dry weights between the two rootball types. The casing, on the other hand, significantly reduced root dry weights for each rootball type.

Keywords: Arboriculture, root barrier, root development, root growth, root weight, sidewalk damage, trunk diameter, urban forestry.
