Short answer: Trim when the trunk is solid and only some limbs are the problem. Consider removal when much of the tree is dead, the trunk is decaying or split, the lean is new or getting worse, or it's the wrong tree in the wrong place.
A lot of trees that people want removed could be saved with good pruning, and some trees that people want to keep really should come down. Here's a practical way to think it through before you ask for a quote. It's general guidance. For a tree you're seriously worried about, have it looked at in person.
Start with one question: what's the actual problem?
Write down what's bothering you about the tree. The answer usually points toward trimming or removal:
- "Limbs hang over the roof and drop debris." Usually a trimming job.
- "It blocks the sun on my garden or solar panels." Often trimming or crown thinning, sometimes removal.
- "There's a big dead limb." Trimming, unless much of the tree is dead.
- "It's leaning toward the house and the lean is new." This needs a look soon, and may mean removal.
- "Mushrooms are growing at the base." Possible root or trunk decay. Have it checked.
- "I want the space." That's removal, and that's a perfectly fine reason.
Signs trimming is probably enough
- The trunk is solid, with no big cavities, cracks or fungus.
- Most of the canopy leafs out normally in season.
- The problem limbs are a minority of the tree.
- The tree is a species that tolerates pruning and is a reasonable size for the spot.
Good pruning means cuts just outside the branch collar, no stubs and no "topping." Topping, which means cutting the whole top off a tree, is widely discouraged by arborists and extension services because it weakens the tree and encourages fast, poorly attached regrowth that can be more dangerous than what was there before. Our tree trimming page covers what good work looks like.
Signs removal may be the better call
- Much of the tree is dead, or a pine is browning from the top down.
- Significant trunk decay: large cavities, conks (shelf fungi) on the trunk, or bark falling away in sheets.
- A split where two big trunks meet, especially with a crack running down.
- A new or worsening lean, or soil heaving up on the side opposite the lean.
- Root damage from construction, trenching or a driveway poured over the roots.
- Wrong tree, wrong place: a large species planted right against the foundation or under power lines will keep causing problems no matter how often it's cut back.

Weigh what it could hit
A tree with a moderate problem standing in the middle of an empty field is a low priority. The same tree over a bedroom is not. Arborists think in terms of the chance of failure combined with what's underneath it. Be honest about both.
Think about cost over time
Trimming costs less today, but a tree that needs heavy pruning every couple of years can add up. Removal costs more once, and then you're done. Many homeowners also ask for stump grinding in the same visit. See our tree removal cost guide for typical national price ranges.
When to get a professional opinion
A tree contractor can give a practical opinion. For something formal, such as a neighbor dispute or an insurance question, ask for an ISA Certified Arborist. Credentials can be checked on the International Society of Arboriculture's website. Ask anyone recommending removal to explain why in plain words. A good contractor should be able to point to the specific problem.
Timing
Many trees are best pruned in late winter while dormant. Dead or hazardous limbs can come off any time, and before hurricane season is a smart window for big trees near the house.
