Also included is their statement on avoiding plants treated with neonicotinoids. "The plant sale has worked hard to make sure our plants have not been treated with neonicotinoids, common pesticides that are now suspected of killing bees and other pollinators." (A more complete statement is on their website, as well.)
The Friends School Plant Sale is entirely volunteer-run. More than 1,000 people do everything from building display tables to shelving plants, and from tallying up orders to packing it all up after the sale is over.
