Several bur oaks were recently planted in Waverly as part of a root-quality study designed to compare nursery growing methods and their adaptability to the landscape. Production methods being evaluated include direct seeding of acorns; traditional plastic containers (10gal); RootMaker™ root trapper bags (7gal); 12” RootMaker™ knit fabric bag; and B&B. Three samples of each have been planted - except B&B which will go in next spring. All trees are planted about 10’ apart in the existing city/school nursery. Growth rates will be recorded annually and root systems will be excavated by air-spade in future years to evaluate for things such as circling, girdling, lateral growth, radial spacing and depth.
