7 Common Tree Care Mistakes Homeowners Make
Updated Jul 2026 · 3 min read
Caring for the trees around your home is mostly common sense — but a handful of well-meaning mistakes can quietly harm a tree or turn it into a hazard. Here are seven of the most common, and what to do instead.
1. Topping a tree to reduce its size
When a tree feels too big, it's tempting to cut the main branches back to stubs. This practice, called topping, is one of the most damaging things you can do. It stresses the tree, opens large wounds to decay, and triggers weak, fast-growing shoots that are more likely to fail later. A skilled arborist reduces size with proper cuts that preserve the tree's structure instead.
2. Piling mulch against the trunk
Mulch is good for trees — but not when it's heaped against the trunk in a "volcano." Mulch piled on the bark traps moisture, invites rot and pests, and can slowly harm the tree. Instead, spread mulch in a wide, shallow ring and keep it a few inches clear of the trunk so the base can breathe.
3. Overwatering or shallow watering
Many homeowners either drown their trees or water too lightly to help. Frequent shallow watering encourages weak surface roots, while soggy soil can suffocate roots. Established trees generally do better with deep, less-frequent watering that reaches down into the root zone, especially during dry spells.
4. Damaging roots during projects
Trenching for irrigation, laying a patio, or grading near a tree can cut or compact the roots that anchor and feed it — and the damage often shows up as decline months or years later. Before digging near a mature tree, plan around the root zone, and consult an arborist if a project will disturb it.
5. Making improper pruning cuts
Pruning helps a tree, but bad cuts hurt it. Cutting flush against the trunk, leaving long stubs, or removing too much of the canopy at once all slow healing and stress the tree. Where and how a cut is made matters, which is why quality pruning is a skill, not just sawing off branches.
6. Ignoring early warning signs
Dead limbs, fungus at the base, a new lean, or cracks in the trunk are the tree telling you something. Putting off an inspection lets small problems grow into big ones — and a hazard that could have been pruned may become a removal. Acting early is almost always cheaper and safer than waiting.
7. Hiring the cheapest bid without checking credentials
Tree work is dangerous, and the lowest quote sometimes reflects thin insurance, skipped cleanup, or crews cutting corners. Choosing a provider on price alone can cost far more if something goes wrong on your property. Verify insurance, get a written estimate, and weigh reviews alongside the number.
Doing right by your trees
Most of these mistakes come from good intentions, and all of them are avoidable. Water deeply, mulch properly, protect the roots, prune correctly or leave it to a pro, watch for warning signs, and hire carefully.
