|Root and Top Growth of a One-Inch Caliper Tree Following Transplanting (Reyes, 2002)
A 1" caliper tree would have a root diameter of 4.5 feet. By nursery standards a root ball of about 1.5 feet would be moved. Less than 5% of the root system is transplanted.
Root and Top Growth of a Four-Inch Caliper Tree
A 4" caliper tree would have a root diameter of 18 feet. A root ball of 3.5 feet would be moved. Less than 5% of the root system is transplanted in the root ball.
The tree is under severe water stress soon after transplanting. With good care the stress diminishes, and the root system diameter should increase to 4.5 feet (100% of the original) by the end of the first year. Roots and top are now balanced and the tree should grow normally.
Root system diameter increases to 6 feet, 9% of original volume. With less than 10% of the absorbing roots to support a full crown (top), the tree is often under severe water stress, inhibiting top growth, including bud formation.
Root system increases to 9 feet, 23% of original volume. The tree is frequently under water stress, inhibiting current season growth.
Root system diameter increases to 12 feet, 41% of original volume. As root/top balance is gradually restored, the tree is exposed to less water stress and growth improves.
Root system diameter increases to 15 feet, 60% of original volume. The effective rate of root generation accelerates as the overall diameter of the root system increases.
Root system diameter increases to 18 feet, 100% of original volume. Roots and crown and the tree should grow normally.
