Pine Problems. What's Wrong with This Pine Tree?

At first glance, this mature pine tree looks healthy. It's tall, established, and still carrying a full canopy.

But a closer inspection tells a different story. In this video, ProGrass Chief Horticulturist Steve Varga walks through the issues he's found on this tree.

While none of these problems automatically means a tree is doomed, each one can affect its long-term health. When multiple issues occur together, they can put significant stress on even a mature tree.

Girdling

Girdling occurs when roots, or in this case an irrigation line, wrap around the tree trunk. As the trunk grows, the movement of water and nutrients is resticted. Many homeowners don't notice it until the tree begins showing signs of decline.

Sequoia Pitch Moth

One of the most noticeable symptoms on this pine is large globs of hardened pitch running down the trunk. This is the work of the Sequoia pitch moth. The larvae tunnel beneath the bark, and the tree responds by producing excessive sap to protect itself. The good news? Healthy trees can often tolerate some Sequoia pitch moth activity. However, repeated attacks can weaken a tree, especially if it's already dealing with other stresses.

Sapsucker Damage

If you've ever noticed neat rows of small holes in a tree trunk, you've probably seen the work of a sapsucker. These woodpeckers drill shallow holes to feed on sap and the insects attracted to it. While occasional feeding usually isn't serious, repeated damage can create wounds that make a tree more vulnerable to insects and disease.

Why Tree Inspections Matter

Trees don't always tell us they're struggling until the damage is well underway.

A professional inspection can identify issues before they become hazardous or irreversible. Sometimes the recommendation is simply to monitor the tree. Other times, corrective pruning, root work, or improved cultural care can significantly extend its life.

The key is knowing what you're looking at.

If you have a mature tree that seems to be declining, is producing excessive sap, or simply doesn't look quite right, Steve can evaluate its health and recommend the best course of action before small problems become expensive ones.
