Tree care by state

Common trees that grow or are often planted in the state, pests and problems worth asking a pro about, the storm season, good pruning timing for the climate, general permit notes and tips for hiring a tree service, with links to each species and pest page.

From well-established tree care knowledge of the kind published by university extension services and state agencies. It is general guidance. For one tree in your yard, ask a local certified arborist or your state extension office.

For many deciduous trees, late winter while the tree is dormant is a good default across much of the US. Warmer states have a longer growing season and some species have exceptions, such as oaks where oak wilt is a concern. Each state page and species page gives more detail.

It depends on your city or county, not only the state. Many cities protect large, heritage or native trees and some need a permit before removal. Call your city planning or forestry office first. Short explanation, not legal advice.

Some states license or register tree work and many do not. Pesticide, contractor and city rules can still apply. Each state page links to our state rules page with official sources.

Search Google Maps, read recent reviews and get two or three written quotes. Ask for proof of liability and workers compensation insurance, and check the state rules page for any license. Our guide on how to hire a tree service has the full steps.

Stay away from downed lines and call the utility. Call 911 if anyone is in danger. Do not climb or cut storm-loaded wood yourself. Take photos for insurance and call an insured tree pro once it is safe.

Send a state or species link to a customer who asks about timing, pests or permits. If you want more of those calls answered and booked, see our Never-Miss-A-Job System, our state marketing pages or ask for a free audit.
