The Effects of Nursery Production Methods on the Growth and Survival of Bur Oak

This study compared the transplanting and survival of balled in burlap (B&B) vs. Knit Fabric Container grown bur oaks. It also compared trees that were spring planted vs. August planted. All trees were spring dug. Trees planted in August were held in RootBuilder® containers after digging. Survival rates and height were significantly better in August transplanted trees. Nine of 16 B&B spring planted trees died. Of 16 trees in each treatment losses in fabric bag spring planted, B&B August planted, and fabric bag August planted were 2, 2 and 1 respectively. The purpose of August planting was to bypass the oviposition period of the Two-Lined Chestnut Borer (TLCB). Although the trees were planted in a turf landscape among mature oaks, none of the trees were attacked by the TLCB during the study.By Thomas Green, Connor Shaw, Fredric Miller and George Ware.

Arrowwood Growing/Planting Study

Derek Snyder, one of our very talented interns, did a study of Viburnum dentatum. It involves the growing and irrigation method used on the plants and the outcome produced after planting in the landscape.
