Container Trees: Superior Growth and Resilience
When it comes to new tree installations, container-grown trees offer significant advantages over their dug (B&B) counterparts, particularly in growth rate and survival.
Faster, More Robust Growth: A 3-inch caliper container red oak will consistently outpace a similarly sized dug red oak over the first three years post-planting. This superior growth stems from container trees being planted with 100% of their root system intact, whereas dug trees lose approximately 60% of their roots during harvesting.
Consider this three-year growth comparison:
Year 1: Container trees add 2 feet of branch growth; dug trees add 0.5 feet.
Year 2: Container trees add 3 feet; dug trees add 15 inches.
Year 3: Container trees add 3 feet; dug trees add 2 feet.
Over this period, a container tree will achieve 8 feet of total branch growth, doubling the dug tree's 4 feet. Furthermore, the container red oak will reach a 6-inch trunk width, an inch wider than the dug tree's 5 inches, delivering an "extra inch of trunk growth" and proving its superior value.
Higher Survival Rate & No Summer Shock: Planting in warm weather, such as a 95.4°F July, highlights another key difference. Dug trees, with their reduced root systems, struggle to absorb enough water to counteract evaporation, leading to transplant shock and browning leaves. In contrast, container red oaks, with their complete root systems, are unaffected by such heat. In my professional opinion, container trees have a significantly higher survival rate, as they experience no transplant shock.
