Tree University: Dwarf Conifers in the Home Landscape Virtual Series
Chadwick Arboretum Volunteer, Joe Stewart, led us in this 1-hour Zoom conversation about Dwarf Conifers for the Home Landscape!
Joe's first garden was in 1970 - six tomato plants at his OSU campus area apartment. His enjoyment of plants has grown through the years, and in 2000, Joe purchased his first conifer. His love for conifers exploded over the next nine years and he and his wife now have about 170 different species of conifers and assorted other plants over a 1/3 of an acre lot!
In this 45 minute presentation and 15 minute Q&A, Joe spoke about the different varieties that he has had luck with, how to maintain them, and why you need 170 in your lot, too.

Jennifer will talk about the motions of the planets in our solar system, how we see them on the Earth, and why we sometimes get lucky enough to have two beautiful planets together.
