What to know

University extension experts writing this month recommend moving leaves into garden beds instead of bagging them. They point out that many native bees, moths and butterflies spend the winter in leaf litter.
A blanket of whole leaves 2 to 3 inches deep insulates soil, holds moisture and breaks down into humus, according to a University of Maine plant researcher.
Lawns still need light. Thick, matted leaves left on grass can smother it, so rake or blow them onto beds or mulch a thin layer into the turf.
Burning leaves is banned in many places. New York and Delaware prohibit it statewide, and on Monday 151 of Texas' 254 counties were under burn bans because of dry conditions.
Cities are rolling out their 2026 pickup schedules now. Check your town's rules before raking to the curb.

Why "leave the leaves" is back in the conversation

Every October brings the same weekend ritual of rakes, blowers and stacks of paper bags at the curb. This fall, more experts are advising homeowners to do less of it.

In an Oct. 6 column, North Dakota State University Extension horticulturist Esther McGinnis urged gardeners to take a lazier, messier approach to fall cleanup. She pointed to recent research showing benefits for birds and pollinators. Three days later, the University of Maine published an essay by plant researcher Manjot Kaur Sidhu arguing that clearing every leaf strips away the foundation of a yard's ecosystem. Sidhu recommends that the first step of fall yard care be doing less, though not nothing.

Both build on a long-running campaign by the Xerces Society, a nonprofit that works on invertebrate conservation. Its "Leave the Leaves" guidance asks homeowners to think twice before they rake, mow and blow.

What lives in your leaf pile

Most insects don't fly south. They spend the winter close to where they lived all summer, hidden and less active.

According to the Xerces Society:

Woolly bear caterpillars and great spangled fritillary caterpillars tuck into leaf piles for protection from cold and predators.
Luna moths and swallowtail butterflies disguise their cocoons and chrysalises as dried leaves.
Mated queen bumblebees burrow only an inch or two into the ground to hibernate, and an extra layer of leaves gives them welcome protection.

Sidhu wrote that fireflies, whose larvae hunt under damp leaf litter for up to two years, and predatory ground beetles that eat aphids and slugs in spring also depend on fallen foliage. McGinnis noted that the mourning cloak butterfly overwinters under a thick blanket of leaves and is among the first butterflies to appear in spring.

Shredding is part of the problem. Raking or shredding leaves can destroy those cocoons and eggs, Sidhu wrote, and the Xerces Society recommends avoiding a mower altogether in beds.

What leaves do for your soil

Leaves are more than habitat. Sidhu explained that trees pull calcium, magnesium, potassium and nitrogen up from deep soil into their foliage. When the leaves fall and decay, those nutrients return to the ground.

As fungi, earthworms and tiny soil animals break leaves down, they form humus. That material improves soil structure, helps sandy soil hold water and reduces erosion in heavy rain, according to the University of Maine essay. A layer of intact leaves also works as insulation, softening the freeze-thaw cycles that can heave soil and damage roots. It can suppress spring weeds without herbicides, too.

McGinnis added a regional note. With El Niño possibly bringing less snow than usual to the upper Great Plains this winter, she wrote, leaves can stand in as insulation for marginally hardy plants.

How to leave the leaves without losing your lawn

"Leave the leaves" doesn't mean letting the yard go wild. The experts agree on several practical steps.

**Move, don't remove.** Rake or blow leaves off the lawn and sidewalks into flower beds, around shrubs and tree bases, or into vegetable plots. Sidhu suggests a layer 2 to 3 inches deep. The Xerces Society says leaves don't have to stay exactly where they fall.
**Keep the lawn breathing.** Too many leaves can kill grass, the Xerces Society warns. If you mulch leaves into turf, McGinnis' rule of thumb is that about half the lawn should still be visible afterward. She suggests passing the mower two or three times over a light layer.
**Mulch mowing is a trade-off.** The experts differ here. McGinnis endorses mowing a light leaf layer into the lawn for its nitrogen and weed-shading benefits. Sidhu and the Xerces Society point out that mower blades kill overwintering insects, so they recommend keeping leaves whole in beds. A practical compromise is to mow lightly on the lawn and leave whole leaves in the beds.
**Choose quieter tools.** The Xerces Society suggests rakes or electric blowers, which keep leaves whole.
**Mind the ticks.** Leaf litter can shelter ticks. Sidhu recommends moving leaves away from play areas, paths and patios to areas people visit less.
**Leave some stems standing.** McGinnis recommends leaving asters, coneflowers, black-eyed Susans and native grasses standing over winter. They feed birds such as goldfinches and chickadees, and some swallowtails overwinter as chrysalises on stems.
**Wait to clean up in spring.** Both the Xerces Society and Sidhu advise holding off until temperatures stay consistently warm, well into spring, so overwintering insects have time to emerge.

Don't burn them

Burning leaves may seem like an easy fix, but it is often illegal and it is hard on the lungs.

Delaware has prohibited leaf burning statewide since 1995, according to the state's environmental agency, DNREC. The agency says leaf smoke contains particulate matter, carbon monoxide and at least seven known carcinogens. Iowa's Department of Natural Resources warns that smoke from burning leaves and grass carries soot, carbon monoxide and benzo(a)pyrene, and that pollution near burn sites can exceed health standards. The department encourages composting, mulching or bagging instead. New York also bans leaf burning statewide, according to the state Department of Environmental Conservation.

Dry weather adds another reason to hold off. As of Monday morning, 151 of Texas' 254 counties had outdoor burn bans in effect, according to a tracker that draws on Texas A&M Forest Service data. The tracker lists Orange County, Texas, among the newest, with a ban that took effect Oct. 23. Rules differ by state and county, so check with your local fire department or county before lighting anything.

What your town does with leaves

If you do bag or rake to the curb, timing matters. Many cities are starting collection now.

**Waukesha, Wisconsin** began fall leaf collection Monday, Oct. 26. Crews plan to pass every home twice and post progress on an online map. The city encourages residents to consider mulching or composting first.
**Clawson, Michigan** started curbside collection Oct. 13. It runs through Dec. 3, and the last bagged-leaf pickup is Dec. 16. The city warns that leaf piles placed in the street before the season can be ticketed.
**Philadelphia's** 2026 Leaf Recycling Program runs Nov. 2 through Dec. 19. Leaves go to a city composting center, and residents can pick up free compost and mulch. Bagged leaves must go in brown paper bags. Leaves put out with regular trash won't be composted.

Those programs matter on a national scale. The Environmental Protection Agency estimated that Americans generated 35.4 million tons of yard trimmings, including leaves, in 2018. That was about 12% of municipal solid waste. About 63% of it was composted or mulched, but landfills still took in about 10.5 million tons. EPA notes that its figures don't count backyard composting, which is one more reason to keep some leaves at home.

The bottom line

A yard that looks a little less tidy in November can mean more butterflies, healthier soil and fewer bags at the curb. Clear the lawn, sidewalks and storm drains. Move leaves to beds. Skip the burn pile. Then check your town's pickup calendar for whatever's left.
