Each tree and plant is guaranteed to grow, or we'll replace it within one year of shipment.
Our trees are delivered with natural bare roots which have been dipped in hydrating gel prior to shipment to keep the roots moist and healthy. As their abundant, fibrous roots aren't confined by a container, bare-root trees get off to a more vigorous start compared to containerized roots which typically need more time to adjust to transplanting. Bare-root trees typically surpass the size of larger containerized trees in only a few years.
Potted (also called containerized) trees are shipped in 4" containers. Because the roots are packed in soil, the trees don't
need to be dormant for shipping. Benefits to potted trees include:
Natural root (also called bare root) trees are shipped without soil around their roots. They are shipped when dormant in the spring and fall seasons. We dip the roots in a hydrating gel to keep them moist during shipping. Some advantages of natural root trees:
