Homeowners are being urged on May 21 to reconsider their approach to fall garden cleanup, as excessive deadheading of flowers may harm native bees and other pollinators. The guidance highlights that removing every flower head in autumn can eliminate essential food sources, shelter, and nesting spots for bees during winter.
The issue is important because many native bee species rely on the remains of plants—such as seed heads, hollow stems, and leaf litter—for survival through colder months. These plant materials also support butterflies, birds, ladybugs, and soil life. Experts recommend leaving some native perennials standing through winter instead of cutting all flower beds down to the ground.
“Deadheading flowers in spring and summer makes sense. It keeps many plants blooming longer,” the article says. “But fall is different… Those ‘ugly’ stems, dried flowers, seed heads, and leaves can become food and cover for native bees.” The article advises cleaning up selectively by removing diseased plants or clearing walkways but suggests not scalping entire gardens.
Native solitary bees do not live in large colonies like honey bees; instead they use what yards provide for overwintering. University recommendations include leaving extra stem on certain plants such as raspberries or sunflowers to create habitat for next season’s pollinators. Leaves left in garden beds act as insulation for insects and plant roots but should be removed from lawns to prevent turf damage.
The article notes that deadheading remains appropriate when managing annuals for continued blooming or controlling disease spread among plants. For a balanced approach that maintains yard aesthetics while supporting pollinators, gardeners are encouraged to use methods like trimming only the front edge of beds while allowing natural growth at the back.
In conclusion, experts emphasize planting more native perennials and avoiding an overly aggressive fall cleanup routine. “Your fall garden is full of seed, shelter, and future pollinators,” the article states. Homeowners seeking assistance with seasonal lawn care are advised they can request services tailored toward protecting pollinator habitats.
