Tree care · Midwest
Wisconsin has long, cold, snowy winters and warm summers, with Lake Michigan and Lake Superior softening the weather along the shores. Maples, oaks, pines, birches and basswood fill the yards and the northern woods. Summer thunderstorms and heavy wet snow are the main reasons limbs and trees come down.

After a storm, stay away from downed lines and call the utility. Call 911 if anyone is in danger. Read what to do after a storm and our storm guides.
Winter is a popular time to prune many trees while they are dormant and the ground is frozen. Oaks need extra care, so ask an arborist or your extension office when oak pruning is safe in your area because of oak wilt.
Each species page lists its own best and worst times. See the month-by-month tree care calendar and when to prune.
Many cities and counties have tree ordinances, and some protect certain trees or require a permit before removal, so check with your city or county before work starts. This is a short explanation, not legal advice.

For tree service owners
Winter, while trees are dormant, works well for many species. Oaks are the exception to watch, because timing matters for oak wilt. Ask a certified arborist or your extension office about the right window for your tree.
There is no single rule for the whole state. Many cities and villages have tree ordinances, especially for street trees and some large trees. Check with your municipality before you cut. This is a short explanation, not legal advice.
We found no state license made just for cutting or removing trees. Treating trees with pesticides for hire needs state certification and licenses. Check the state rules page and ask for proof of insurance.
Ask an arborist about the condition of your ash trees, since emerald ash borer has hit ash trees hard in the Midwest. Dead ash can turn brittle and drop limbs, so have them checked.
Road salt can wash into the soil and splash onto trees near streets and driveways, which can stress roots and needles. An arborist can help you spot salt damage and plan around it.
Stay away from leaning or split trees and anything touching a power line. Call the utility for downed lines and 911 if anyone is in danger. Then call an insured tree service.
