Ecotreat, a division of Groundworks of Palm Beach County, Boynton Beach, Fla., offers a patent-pending process for the preparation of mature landscape material shipments into markets that do not allow soil imports. Using the Ecotreat method, all of the native soil from the root systems of mature green goods is removed and the bare root systems are dipped to eliminate pests that may be present. After sanitation, a new phytosanitary root encasement is created around the roots. This encasement is constructed using a phytosanitary organic material that has been pre-processed to be basically sterile. The result is an air-free, durable and completely phytosanitary root encasement that protects the root system during shipping and handling, promotes root regeneration and allows for ease of re-installation.
