Pollinator gardens face risks from toxic plants and pesticides

Gardeners attempting to support declining bee populations may inadvertently cause harm through the selection of certain plants. Some species are naturally toxic to honey bees, while others pose a significant threat due to nursery treatments.

A 2014 report by Friends of the Earth US and the Pesticide Research Institute found that 51 percent of so-called ‘bee-friendly’ plants from major retailers contained neonicotinoid pesticides. These systemic insecticides are absorbed into the plant, including its nectar and pollen, making them impossible for bees to detect or avoid.

To support pollinators effectively, experts suggest using native, self-seeding plants such as tickseed, coneflower, milkweed, and bee balm. These species provide vital food sources for bees, butterflies, and hummingbirds while requiring less maintenance through natural spreading.
