 December 12, 7 – 8pmAdaptive Gardens James Wilson

Please join us for an evening with James Wilson, owner and lead designer of “Garden Stories,” a landscape design/build company in Portland. He will discuss how to understand and cultivate gardens of resiliency in changing times. Gardening in the 21st century may require a whole new perspective on how we think about residential gardens and designing spaces for both human and ecological interests.  Your garden can simultaneously be an ecologically beneficial landscape that is well-planned and beautiful throughout the season using native and adaptive plants.

March 14, 7 – 8pm:  Heat of the Moment: How Climate Change Impacts Insects in Our Garden –  Dr. Gail Langellotto, OSU click for recorded video

Gardeners have seen the effects of climate change — warmer winters, wilder swings in weather change, prolonged drought, and intense wildfires. To garden well in these times requires a new understanding of how the changing climate affects other players sharing our garden ecosystem.

A major presence in our gardens are insects. Being ectotherms, their body temperatures and biochemical processes are directly affected by air temperature. As a result, any change in the climate has an immediate and significant impact on them. Geographic range expansion, phenological changes, heat stress, and disruption to natural relationships between insects and plants are some examples.

This lecture addresses how climate change affects insects and what gardeners can do to prepare for and mitigate climate change and its effects.

Dr. Gail Langellotto is an insect expert and Professor of Horticulture at Oregon State University. Together with her lab group, the OSU Garden Ecology Lab, she studies the plants, insects, people, decisions, and management practices that either improve or degrade a garden’s ability to promote environmental and human health. She also serves as the Extension Urban and Community Horticulture Specialist and the Statewide Extension Master Gardener Program Coordinator.

September 12, 7 – 8pmAdapting Your Yard and Garden to Climate Change –  Weston Miller

Our September program will feature our own Weston Miller who will present “Adapting Your Yard and Garden to Climate Change”.   Climate change touches the natural ecosystem in countless ways, and its impact can be seen in our own backyards – and front yards as well as community gardens. Temperature changes and weather events are affecting which plants are thriving in our gardens and which ones are dying.  We will all benefit from Weston’s expertise as he suggests the ways we can adjust our landscapes to the changing weather patterns. 

Weston Miller has been the manager of the OSU Master Gardener Program in the Portland metro region (Clackamas, Multnomah, and Washington counties) since 2007.


 October 10, 7 – 8pmHow to Identify the Emerald Ash Borer – Dr. Gail Langellotto, OSU

The Emerald Ash Borer was discovered in Forest Grove Oregon, marking the first confirmation of this insect on the West Coast.  This pest has proven destructive to ash trees including the Oregon native ash tree. 

In this presentation, Gail Langellotto  will teach us  the importance of early detection in stopping the spread and establishment of this new and emerging species.   Specifically, you will learn how to recognize ash trees, identify the emerald ash borer, and what to do if you suspect that you have found an affected tree, or the invasive pest.
