SERVICE AREA • MANDAN, ND
Landscaping in Mandan, ND
Bismarck Landscape does lawn care, tree work, snow removal, sprinkler service, cleanups and full yard installs for homes and businesses in Mandan. Mandan sits just across the Missouri River from Bismarck, so the soil, weather and frost dates are the same. The city rules are not.
Mandan has its own grass height limit, its own snow rules and its own grass and branch sites, and it’s in a different county for the emerald ash borer quarantine. This page covers what’s different, so your yard work stays on the right side of Mandan’s rules.

CLAY SOIL • WIND • SHORT GROWING SEASON
What Mandan Yards Deal With
- Clay soil that drains slowly and packs hard, especially on newer lots
- Alkaline soil that turns lawns and maples yellow. NDSU says North Dakota soils often run pH 8.5 to 9.0.
- Wind across open lots and hillsides
- Sloped lots, where water from uphill needs a swale or drain to get around the house, and walls can turn a slope into usable yard
- Lower ground near the rivers, where drainage needs extra attention
- A short season, with only about 129 days between frosts
The same lawn, tree and sprinkler calendar works on both sides of the river. See our Bismarck yard care calendar.

| Clear sidewalks | Within 24 hours after the snow | Within 24 hours after the snow stops |

Snow. The City of Mandan says property owners must clear all snow and ice from their sidewalk “within 24 hours after its deposit,” or the city may clear it and bill the owner. The city prohibits snow on “a sidewalk, driveway apron, on the paved portion of a street or alley,” but says “snow may be placed in the unpaved portion of the boulevard within the public right-of-way.” Keep the area around fire hydrants clear. Mandan generally plows all routes at about 4 inches of snow. For snow questions, call Mandan Code Enforcement.
Grass. Mandan’s limit is lower than Bismarck’s. The city’s property maintenance page says “the height restriction is 6 inches,” and owners must mow tall grass or spray weeds by May 1, June 1, July 1, August 1, September 1 and October 1. For tall grass reports, contact Mandan Code Enforcement.
LOCAL COLLECTION SITES • MORTON COUNTY
Where Grass, Leaves and Branches Go in Mandan
Bismarck’s yard waste sites are for Bismarck residents. Mandan runs its own grass and branch collection sites:
| Site | What it takes |
|---|---|
| Old Red Trail and Hillside Road NW | Grass, leaves, garden waste |
| Mandan Brave Center, 901 Division Street NW | Grass, leaves, garden waste |
| 8th Avenue SE and Highway 1806 South | Grass, leaves, garden waste, plus branches under 4 inches across |
| 24th Avenue SE and Longspur Trail | Grass, leaves, garden waste |
| McKenzie Drive SE and 34th Avenue SE | Grass, leaves, garden waste |
A few rules:
- Sites usually run from spring through fall, often opening around early March once dumpsters can go out.
- Bags go in the trash cans, not the dumpsters.
- Bigger branches go to the landfill, which the city says charges Mandan residents $15 per ton.
- Contractors can’t use the grass sites. They can use the landfill’s compost pile at no charge for loads of only grass, leaves or garden waste, and pay $20 per ton for branches.
- Illegal dumping at the sites carries a $500 fine.
Questions go to Mandan Public Works.
EMERALD ASH BORER • COUNTY RESTRICTIONS
Ash Trees and Emerald Ash Borer in Mandan
Emerald ash borer was found in Bismarck in August 2026. The North Dakota Department of Agriculture lists detections in LaMoure, Cass and Burleigh counties. Morton County is not on that list.
That doesn’t mean Mandan’s ash trees are safe:
- NDSU recommends treatment when emerald ash borer is within 15 miles, and Mandan is close to Bismarck, where it was found.
- Ash wood can’t come from Bismarck to Mandan. Wood from Burleigh County can’t leave the county without a permit, and fines can reach $5,000.
- Mandan’s own code addresses Dutch elm disease and emerald ash borer in Section 16-4.
If you have an ash in your Mandan yard, now is the time to decide whether to protect it. See should you treat or remove your ash tree and our emerald ash borer guide.
BOULEVARD TREES • CITY FORESTRY
Boulevard Trees in Mandan
Mandan’s boulevard rules are different from Bismarck’s. The city’s forestry page says Section 115-4 of the city code addresses vegetation on boulevards, and the city has announced a boulevard tree planting program offering a $75 reimbursement per tree. Mandan’s Forestry Division is a two-person team led by the grounds maintenance superintendent, so check with the city before planting, pruning or removing a boulevard tree.

Questions
Mandan Landscaping FAQ
Answers to local questions about Mandan mowing, snow, yard waste and ash tree restrictions.
Need to compare rules on both sides of the river?
See Mandan city rules, the local grass and branch sites, and our ash tree guidance.
Do you do landscaping in Mandan?
Yes. Bismarck Landscape does lawn care, tree work, snow removal, sprinkler service, cleanups, patios, walls and full yard installs in Mandan, ZIP code 58554, as well as Bismarck and Lincoln. We follow Mandan’s own snow, mowing and yard waste rules.
How tall can grass get in Mandan?
Six inches. The City of Mandan says the height restriction is 6 inches, and owners must mow tall grass or spray weeds by May 1, June 1, July 1, August 1, September 1 and October 1. That’s stricter than Bismarck’s 8-inch limit.
Can I put snow on the boulevard in Mandan?
Yes, on the unpaved part. The City of Mandan says snow may be placed in the unpaved portion of the boulevard, but not on a sidewalk, driveway apron, or the paved part of a street or alley. Sidewalks must be cleared within 24 hours.
Where can I take grass and branches in Mandan?
To Mandan’s five grass collection sites, which take grass, leaves and garden waste. The site at 8th Avenue SE and Highway 1806 South also takes branches under 4 inches across. Bigger branches go to the landfill, which charges Mandan residents $15 per ton.
Is Mandan under the emerald ash borer quarantine?
The North Dakota Department of Agriculture lists emerald ash borer detections in LaMoure, Cass and Burleigh counties, and Morton County isn’t on that list. But Mandan is close to the Bismarck find, and NDSU recommends treatment for valuable ash within 15 miles of a known infestation.
Can I bring ash wood from Bismarck to Mandan?
No. Burleigh County is under the emerald ash borer quarantine, so ash logs, branches, wood chips and hardwood firewood can’t leave it without a permit. Mandan is in Morton County, so hauling Bismarck ash wood there breaks the quarantine. Fines can reach $5,000.
