A Homes & Gardens report outlines seven October garden practices that can give wild bees places to overwinter, including retaining leaf litter and delaying some plant cleanup. Experts say nesting habits vary by species, so gardeners should preserve suitable habitat while keeping paths and drains clear.
A Homes & Gardens report recommends that gardeners make modest changes to October cleanup to help wild bees overwinter, including leaving leaf litter and some plant stems undisturbed. The advice, attributed to specialists from the Xerces Society for Invertebrate Conservation and the U.S. Geological Survey, focuses on preserving nesting and hibernation sites rather than maintaining a uniformly cleared garden.
The report describes seven approaches: retain leaf litter in suitable places; leave some perennial and annual stems standing; avoid composting seed heads and stems that may contain nesting bees; keep suitable hollow stems or other nesting materials available; limit fall pruning and deadheading; avoid pesticides; and keep habitat while still clearing areas where leaves create hazards. Its supplied text details the first two recommendations and introduces the third, but does not provide the full explanations for all seven.
Bee overwintering habits differ by species and location. USGS wildlife biologist Sam Droege says wild bees may nest above ground, though a larger proportion nest in the ground. Xerces Society outreach director Matthew Shepherd says many solitary bees develop inside nest cells, including in underground sites and existing tunnels in hollow stems. Bumblebee colonies follow a different cycle: most colony members die at summer’s end, while new queens overwinter underground or in leaf mulch.
Shepherd recommends keeping leaves on flower borders, at hedge bases or in a back corner, while removing them from paths where they could cause slips and from drains where they could block water flow. He also says leaving plant stems can provide nesting opportunities for tunnel-nesting bees. Droege suggests that gardeners under pressure to keep a front yard tidy could cut plants back to about a foot rather than removing them entirely. The report advises avoiding pesticides, but provides no product-specific directions; any pesticide use must follow its label and include the protective equipment specified there.
Garden Cleanup Can Preserve Bee Habitat
Fall cleanup can remove the places where some native bees spend winter or complete development. Retaining portions of leaf litter and stems offers habitat with little need for new equipment or planting, while selective clearing can address practical concerns such as slippery paving and blocked drains. The recommendations are relevant to gardeners who want to support pollinators without leaving every part of a yard unmanaged.
The report distinguishes wild bees from honey bees, arguing that conservation attention should include native species. It says there are more than 3,600 bee species native to the United States, but gives no underlying dataset or date for that figure. Its broader point is that a single tidy-up routine may remove habitat used by different species in different ways.

Different Bees Spend Winter Differently
The report says solitary bees make up most bee species and include mason, leafcutter, long-horned and mining bees. Many remain in nests through winter, with offspring developing in individual cells provisioned by the mother. According to Shepherd, some species use tunnels in hollow stems and similar materials, while many nest in the ground.
Bumblebees have social colonies during the warmer months. Shepherd says most members die near the end of summer, leaving new queens to hibernate and emerge in late winter or early spring. Because local species and conditions vary across regions, the report presents general habitat guidance, not a guarantee that a particular garden feature will serve every bee.
“No matter where you are a certain proportion of wild bees will be nesting above ground and a larger proportion in the ground somewhere.”
— Sam Droege, wildlife biologist at the U.S. Geological Survey, as quoted by Homes & Gardens

Local Species and Seven Tips Need Detail
The supplied source text does not include the complete descriptions of all seven practices: it ends as the third recommendation, about seed heads and stems, begins. The remaining steps and their qualifications cannot be independently specified from the material provided. The report also gives no local species list or regional calendar, and it does not quantify how much these garden actions affect bee survival. The cited experts describe general patterns, not outcomes guaranteed for every yard.

Choose October Tasks by Garden Site
Gardeners can begin by identifying places where leaves and stems can remain without obstructing paths, drains or routine access. Retain leaf litter on beds or in a tucked-away corner, and consider leaving some stems standing through winter. Where a complete no-cleanup approach is impractical, selective trimming may preserve some structure. Local extension services or conservation groups can offer guidance suited to regional bee species and climate; the report does not specify a follow-up date or further official action.

Key Questions
What should I leave in the garden for overwintering bees?
The report recommends retaining leaf litter in suitable areas and leaving some perennial or annual stems standing. These features may provide hibernation or nesting sites for some wild bees.
Should I leave leaves on paths and near drains?
No. Shepherd advises removing leaves where they could create a slip hazard or block drains, while keeping them on flower beds, near hedges or in a back corner.
Do all bees overwinter in hollow stems?
No. The report says bee species differ: many solitary bees nest in the ground, while some use existing tunnels in hollow stems. Bumblebee queens may hibernate underground or in leaf mulch.
Can I tidy a front yard and still help bees?
Droege suggests cutting plants to about one foot tall as a compromise rather than removing all stems. The source presents this as general advice, not a rule for every plant or local species.
Does the report provide all seven recommendations?
No. The source material provided includes the first two recommendations and the beginning of a third, but not the full details of all seven. It does advise avoiding pesticides; if using any, follow the product label and wear the protective equipment it specifies.
