Tree Trimming & Pruning in Minnesota

Minneapolis: boulevard trees (between curb and sidewalk) are owned and maintained by the Minneapolis Park and Recreation Board. Residents may not remove them, and significant work requires MPRB permission. The MPRB can also condemn diseased or hazardous private trees (such as those infested with EAB or Dutch elm disease) and order their removal.

Bur and red oak: long-lived; red oaks very susceptible to oak wilt Green and white ash: widely planted; lethal EAB risk unless treated Silver maple: large, fast-growing, weak-wooded; storm breakage

Nov–Mar: Prime removal season: frozen ground, dormant trees, crews available April–July: Avoid pruning oaks (oak wilt); spring snow on leafed trees

Summer thunderstorm complexes can flatten trees across wide areas.

Present in the Twin Cities area and much of central and southeast Minnesota.

Kills untreated ash; dead ash become brittle and hazardous within a couple of years.
