| Quercus macrocarpa Bur oakCulture: The bur oak is a very tough and adaptable species. This species tolerates heavy clay soils and will even survive in urban conditions. It is pH adaptable, durable and very long-lived. Specimens of 200-300 years of age with massive trunks are common in the Midwest. Although difficult to transplant due to a large tap-root, once established it is a true survivor. Specimens of 2" caliper transplant much more easily than 4" and larger sizes. The University of Wisconsin Madison campus has a few old bur oaks that have survived the experience of being rifle shot targets when that area was part of Camp Randall. Like the other oaks, bur oak has several nuisance insects and disease problems, but they usually are not serious. An otherwise healthy tree will not be seriously affected by any of them. Usage: Bur Oak makes a magnificent specimen tree for large home landscapes, parks or golf courses. The increasing emphasis being placed on the use of native plants makes this a prime candidate for your planting palette. Although this species is relatively slow growing, it is one worth planting for your children and grandchildren. |
