A cleared yard leaves a heap that looks like one thing and is really several. Yard debris sorting starts with seeing those categories before they mix. Prunings, dirt, rock, old lumber and broken concrete each have a different destination, and a hauler or the curbside crew may refuse a pile that blends them.
Rules depend on who collects your waste. The examples here come from City of Sacramento guidance. Residents of unincorporated Sacramento County or other cities should check their own provider.
Green Waste That Belongs Together
Plant material forms the easiest group. The City’s 2025 to 2026 service guide lists leaves, grass trimmings and tree and shrub prunings as acceptable in the organic waste container. It asks residents to cut limbs to 3 feet in length or less and no more than 4 inches in diameter.
Sod qualifies as well, once the dirt comes off. That detail catches people during lawn removal, since a strip of turf can carry a lot of soil. Shaking or scraping off what you can keeps the container within the rules.
The same guide lists diseased plants among items that do not go in the organic container. Pet waste and plastic bags stay out too, along with treated or painted wood. Food scraps belong in the container, but never in a street pile.
Large Wood and Stumps
Tree stumps and limbs thicker than 4 inches appear on the guide’s list of unacceptable organic materials. A big tree job can produce plenty of both. Those pieces need another route, such as a tree service that hauls its own wood or a facility that accepts large wood.
Wood chips from grinding are a separate question. Many homeowners keep them for mulch around shrubs and paths. A related post on dealing with woody debris after tree work looks at those options.
Soil, Rock and Concrete
Heavy materials cause the most trouble in mixed piles. The City’s garbage collection page bans dirt, rock, asphalt and construction or building materials from the garbage can. It points residents to certified construction and demolition debris sorting facilities instead.
Excessive sand, dirt or gravel also does not belong in the organic container. Concrete and lumber appear on that exclusion list too. Keep broken patio slabs, edging stones and spare base rock in their own stack.
Some of that material has a second life. Clean soil can fill low spots elsewhere on the property, and intact pavers or stone may suit a new path. The post on what can be reused from a yard demolition walks through those choices.
Treated Wood Needs Its Own Pile
Many old fence posts, deck boards and landscape timbers contain treated wood. California handles treated wood waste under special rules. The Department of Toxic Substances Control says households should not burn it, should keep it separate from other materials and should not remove markings that identify it as treated.
DTSC also says households may store less than 1,000 pounds for no more than 30 days after removing it from use. It must go to an authorized treated wood waste facility. DTSC adds that treated wood must not be chipped, ground or mulched, so it can never join the green waste.
The State Water Board posts a list of landfills authorized to accept treated wood waste. Kiefer Landfill in Sacramento County appears on it. Call any facility first to confirm what it takes, along with hours and any fees, since the list alone does not show those details.
The City service guide excludes treated wood waste from household junk pickups. Its garbage page lists treated wood both among items that go in the garbage and among items banned from the can. Given that mismatch, check with the City before choosing either route.
Mixed Construction Debris
Drywall scraps, wire, plastic pipe and old irrigation parts often surface during a tear out. City guidance sends construction and building materials to sorting facilities rather than the curbside cans. Garden hoses go in the garbage, according to the same page.
Old irrigation lines deserve a quick look before they go anywhere. Plastic pipe and fittings belong with other construction scraps, while brass valves and metal parts may go to a scrap metal recycler. The post on what happens when a concrete patio is removed covers the heavier side of a tear out.
Keeping these small items in a bucket or bin as you work saves time later. Picking wire and plastic out of a brush pile after the fact is slow and frustrating.
City Pickup Options and Limits
The service guide describes a household junk pickup that residents can schedule twice a year between February and October. It can include excess yard waste. The City will collect up to five cubic yards per appointment, about a pickup truck bed. Dirt, rock, rubble and concrete are not accepted.
Leaf season is the other path. The 2025 to 2026 guide allowed yard waste piles in the street from November through February for residents on public streets. Piles could not exceed 4 by 4 by 9 feet per household. Dates change each year, so confirm the current season before building a pile.
Yard Debris Sorting on Cleanup Day
Weight is worth planning for too. Soil and broken concrete get heavy fast, and a trailer or truck bed has limits. Splitting heavy material into several smaller loads protects the vehicle and keeps each trip within what the receiving site will take.
Set up separate zones before any digging begins. One spot holds plant material that fits the organic container. Another holds large wood and stumps. Soil and rock get a third area, with concrete beside them.
Treated wood gets its own marked stack, away from anything that might be chipped. A small bin collects wire, plastic and hardware. That kind of yard debris sorting makes each load easier to route and reduces the chance of a rejected pickup.
Contractors handling a cleanup should explain where each material will go. If they plan to haul everything in one load, ask how the receiving facility sorts it. Good yard debris sorting on site often costs less effort than sorting at the end. Other cleanup topics appear in the demolition and cleanup category.
