Mason Bee Box

Arboretum staff will be assisting mason bee hobbyist Dave Richards (JohnnyAppleBeez, LLC) install several mason bee boxes in trees throughout the Arboretum grounds. The gentle, native mason bee is a better pollinator than the honeybee, but doesn’t travel nearly as far from its nest. Boxes will be up until June. An interpretive sign about mason bees will soon be posted up at the Arboretum apiary.

8 boxes similar to the one in the photo will be installed throughout the Arboretum grounds

J.A. Witt Winter Garden: SE Bed Renovations

February 18th, 2010 by UWBG Horticulturist

The UWBG horticultural crew will be making renovations to the southeast bed, which will include removing, relocating, or protecting other UW plant collections in the project area, followed by regrading of the bed and soil remediation. The 2009-2010 fall and winter planting of new winter-interest trees, shrubs, and ground covers will also take place.

This project will reclaim over 5,000 sq. ft. of bed space that is now detrimentally shaded by elm trees. It will also renew UW Landscape Architecture Professor Iain Robertson’s original 1987 Winter Garden design intent.

This renovation was made possible by a gift from the Arboretum Foundation, which was given to them from Lake Washington Garden Club, Unit 3.
