Tree Shopping Facts and Myths

Co-owner and lead botanist Kelsay Shaw shares some guidelines on how to choose trees, with reference to their parts and things to consider, both good and bad. These should not be considered hard and fast rules, but rather a helping hand in determining either if a tree has a potential problem or if it is truly a "stinker."

From Potential to Practical: Conserving Bees in Urban Public Green Spaces

Urban pollinators are challenged by habitat loss, degradation, and fragmentation. Nevertheless, cities often support rich bee faunas, and public green spaces such as parks, gardens, and vacant land offer tremendous potential if managed as bee habitats. When designing urban bee habitats, ecologists must optimize pollinators’ needs in a manner that both is economically feasible and respects societal norms and values. Codesigning public green spaces with a diverse team of stakeholders is therefore necessary to achieve long-term pollinator conservation in cities

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.
