How to Tell If a Tree Is Sick and Needs to Be Removed

Posted by: USA Tree Experts LLC – Southington, CT

If you’re like most homeowners, you probably don’t think much about your trees—until something starts to look off. We’ve worked on hundreds of properties throughout Southington and the surrounding towns, and one thing we’ve learned is this: sick trees don’t always announce themselves. Sometimes the signs are obvious. Other times? Not so much.In this post, I’ll walk you through some of the most common warning signs we look for when we’re out removing trees or inspecting properties. Whether you’re dealing with a massive oak or a small ornamental tree, here’s how to tell if it’s time to take a closer look—and maybe call in the pros for safe removal.

Visible Signs a Tree Might Be Sick

If you’re wondering “how do I know if my tree is dying or diseased?”—start here. Below are some signs we often spot before or during tree removal jobs:

  • Dead or brittle branches, especially in the upper canopy
  • Discolored or spotted leaves in the growing season
  • Peeling or cracked bark that looks dry or is flaking off
  • Mushrooms or fungal growth at the base of the trunk (big red flag)
  • Hollow-sounding trunk when tapped
  • Sudden leaning or shifting in posture
  • Excessive leaf drop outside of normal seasonal changes
  • Unusual insect activity or visible infestations
  • Soft or rotting spots on the trunk or large limbs
  • Visible root damage or mounded soil at the base

What You Can’t See Can Still Be a Problem

We’ve had jobs where a tree looked perfectly fine from a distance, but the moment we cut into it, the interior was completely rotted. One customer in Cheshire had a tree fall during a mild storm—not because of high winds, but because it was completely hollow on the inside. We ended up inspecting the rest of the yard and flagged two others that were showing early signs of decay.

That’s why we always tell our customers: don’t wait for a tree to fall. If it’s close to your home, pool, fence, or driveway—it’s not worth the gamble. We’ve got the equipment and experience to handle even tight removals safely.

A Tree Might Be Sick If…

Let’s say you’re standing in your backyard wondering if that old maple or pine is okay. Ask yourself:

  • Have I noticed fewer leaves this year?
  • Does the tree look “thinner” than it used to?
  • Are limbs falling more often, even in calm weather?
  • Is the bark changing, cracking, or falling off in big patches?
  • Are insects going after it more than usual?
  • Is there a strange smell coming from the base?

These are the little things we’ve learned to look for while walking properties. And when we spot more than one of these signs, it usually means it’s time to remove the tree before it becomes a bigger problem.

When in Doubt, Let Us Take a Look
