7 Signs a Tree Is Dying: Colorado Homeowner Checklist

Colorado is hard on trees. Dry air, intense sun, clay or rocky soil, sudden freezes and years of drought stress all show up in the canopy. The tricky part is that a stressed tree and a dying tree can look alike. This checklist will help you sort out the difference, whether you're in Colorado Springs, Woodland Park, Pueblo or Castle Rock.

First, Rule Out Normal Colorado Tree Behavior

Before you assume the worst, keep these in mind:

• Pines shed old needles. Ponderosa and other pines drop their inner, older needles in fall. Yellowing at the inside of the branches is usually normal. Browning at the tips or across the whole crown is not.
• Late leaf-out is common. Late spring frosts can delay or burn new growth. Give deciduous trees until early summer before calling one dead.
• Winter burn happens. Evergreens can brown on the sunny, windy side after dry winters, and some recover with deep watering.

The 7 Signs a Tree May Be Dying

1. Bare or Brittle Branches in a Leafy Canopy

If one limb stays bare while the rest of the tree is in full leaf, that limb may be dead. If bare branches are spreading from the top down or the outside in, the whole tree is likely declining. Try the scratch test: scrape a small patch of bark off a twig with your fingernail. Green and moist underneath means alive. Brown and dry means dead. Test several twigs, because a tree can be partly alive.

2. Needles Turning Red, Orange or Brown

In pines and spruce, needles that fade to straw, red or brown, especially when the change starts in the upper crown or spreads across an entire branch, are a serious warning. Drought, root damage and bark beetles can all cause it. By the time the needles turn red, the tree is often past saving, and a dead evergreen next to your home is a real fire concern.

3. Pitch Tubes, Sawdust and Small Holes

Look at the trunk and the base of the tree for popcorn-like blobs of resin (pitch tubes), fine reddish boring dust in bark crevices or on the ground, and tiny round exit holes. These point to bark beetles or other boring insects. Beetles generally go after trees that are already stressed, so a tree showing these signs is in trouble. Ash trees with D-shaped exit holes or thinning crowns should be checked for emerald ash borer, so ask your city forester or CSU Extension about current status in your area.

4. Peeling, Cracked or Sunken Bark

Bark that is falling off in sheets, splitting vertically, or showing sunken, oozing or discolored patches (cankers) suggests damage to the tissue beneath. Aspens are especially prone to cankers and borers, and many Front Range aspens struggle at lower elevations because it is hotter and drier than they prefer. A few dark scars are not unusual. Large areas of missing or dead bark that wrap around the trunk are a bad sign.

5. Mushrooms or Conks at the Base

Mushrooms, shelf-like conks or soft, crumbly wood at the root flare often indicate root or heart rot. The fungus is feeding on decaying wood, which means the structure inside may be weaker than the outside suggests. This matters most for large cottonwoods, Siberian elms and older maples, which can fail suddenly in a windstorm.

6. Leaning, Heaving Soil or Exposed Roots

A tree that has always leaned slightly is not necessarily a problem. A tree that has recently started leaning, or one with cracked, lifted soil on the opposite side, may have lost root support. Construction, grade changes, trenching or overwatering can all damage roots. After a storm, a new lean should be treated as an emergency, especially if the tree could reach a house, driveway, fence or power line.

7. Hollow Trunk, Major Cracks or Heavy Dieback

Large cavities, deep cracks, branches that snap with no resistance, and thin leaves that are undersized or discolored all suggest a tree that has lost much of its vigor. Some hollow trees stand for decades, but combine a cavity with other signs on this list and the risk goes up quickly.

Dying Tree or Fixable Problem?

Many problems can be reversed if caught early. Drought-stressed trees often respond to slow, deep watering in winter and summer, a ring of mulch (kept off the trunk), and careful pruning of dead wood. A tree that is more than half dead, has major trunk decay, or has an active beetle infestation is usually beyond recovery. Removing it quickly can also protect healthy neighbors.

If you aren't sure, an in-person look is worth it. A professional can check structure, decay and risk, which is hard to judge from the ground.

Why It Matters in Wildfire Country

Dead and dying trees, especially evergreens with dry needles, are fuel. If your home borders open space or forest, removing dead trees and pruning low branches is a core part of wildfire mitigation and building defensible space. Standing dead trees near a roofline or deck deserve priority.

When to Call a Tree Service

Call promptly if the tree:

• Is close to your home, a garage, a play area or power lines
• Has a new lean, cracks, or exposed roots
• Shows several of the signs above
• Dropped large limbs or was hit by a storm (storm damage cleanup is often needed alongside removal)

If you're local, our crew provides tree service in Colorado Springs and across El Paso, Teller and Pueblo counties and the south Denver suburbs. Removal is priced by height, so you know the cost before work starts. You can see flat tree removal prices online, and cleanup is included. Stump grinding can be added if you'd like to reclaim the space, with stumps from $149.

Check HOA and City Rules First

Rules on removing trees vary by city, county and HOA. Some neighborhoods require approval before taking down a tree, especially in front yards or on common property, and others have none. Check your HOA covenants or your city's forestry office before scheduling. Fire-safety work is often encouraged, but requirements differ, so don't assume.

Next Steps

Walk around your trees this week with this list, do the scratch test on a few twigs, and take photos so you can track changes. If you decide a tree needs to come down, you can book tree removal online or call us at (719) 407-6466. You only pay after the job is done.
