quality root ball

The media has been partially removed on this 15 gallon container oak exposing roots inside. Spinout™ (copper hydroxide) was applied to the inside container wall when the 3 gallon liner was planted into the 15 gallon container 15 months ago. The container is shown on the left with some of the Spinout™ still remaining as shown by a gray color. There were few circling roots on the outside edge of the root ball compared to trees in a traditional plastic container.
