Best Practices in MG Plant Sales

Master Gardener plant sales are a major fundraiser for many Master Gardener Associations. However, recent Oregon Department of Agriculture quarantines and restrictions to the movement of plants and soils in Washington County, Oregon have affected some Master Gardener plant sales and have highlighted the role that plants sales may play in promoting invasive species introductions.

In fact, a recent news story reported on the role of a Coos County plant sale in introducing an invasive weed from India. Other news reports show that the sale of invasive plants, or that the introduction of invasive species via plant sales, is neither unique nor isolated (e.g. ‘Invasive species for sale in Kootenay region’).

And, plant trades between gardens are also potential venues for the movement of native plants. In fact, research conducted in the United Kingdom estimates that ~2 million seeds are moved via the movement of garden soils and soils for new housing developments. Further, the researchers found that the risk of introducing invasive plants was far greater from the movement of garden soils, than other soil types.

Over the next year, a task force will work to develop best practices for Master Gardener plant sales, in order to prevent the introduction and spread of invasive species in Oregon. The task force includes two Master Gardeners, two Master Gardener faculty, and an advisor from the Oregon Department of Agriculture. As we develop specific recommendations, we will post them for feedback and critique. Stay tuned!
