RootBarrier® Arbretio®

ARBRETIO®; the new brand name for KING RootBarrier’s tree planting wedges. The name merges ‘arbor’ (tree) with ‘accretio’ (growing power). RootBarrier® Arbretio® was developed to simplify underground anchoring. Arbretio® is a wooden wedge, that is placed horizontally into the root ball just before the tree is planted. This can be done with simple hand tools.

The wedges anchor the root ball and thereby the tree. Because the wedges function like added roots, root ball rotation in the planting hole is minimal compared to other planting methods, greatly enhancing the tree’s rooting and stability. RootBarrier® Arbretio® is 100% bio-degradable and therefore never needs to be removed. After a few years, when the tree is sufficiently anchored by its own roots, decomposition will set in. In due course the product will be largely absorbed by the soil.
