Each tree is guaranteed to grow, or we'll replace it at one half the original price, plus shipping and handling.
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.
Natural Root and Containerized Trees
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.
There are a number of advantages to natural root trees:
The Urban Horticulture Institute at Cornell University has an interesting article about the benefits of planting natural root trees. Look for the PDF entitled Creating the Urban Forest: The Bare Root Method
Potted (also called containerized) trees come in 4" containers.
