7 Signs Your Tree Needs Professional Attention This Spring

Wondering if your tree needs an arborist? Learn the 7 warning signs Vancouver, WA homeowners should watch for this spring—and when to call a certified tree service.

Spring brings new growth, longer days, and the perfect opportunity to evaluate your trees’ health. As trees emerge from dormancy, they reveal conditions that winter concealed. Some issues resolve naturally with warmer weather. Others demand professional attention before they become dangerous or irreversible.

Knowing the difference saves money, protects your property, and can save trees that might otherwise be lost.

At Ohana Tree Care, our ISA-certified arborists help Vancouver and Clark County homeowners distinguish between normal seasonal changes and genuine warning signs. Here are seven signals that your tree needs professional evaluation this spring.

No Buds or Delayed Leaf-Out

By mid-March, most deciduous trees in Clark County show visible bud development. Swelling buds indicate the tree is actively preparing for spring growth. When neighboring trees of the same species are leafing out but yours shows bare branches, something's wrong.

What delayed leaf-out might indicate:

Winter damage to branches or the entire tree
Root system problems preventing water and nutrient uptake
Vascular disease blocking internal transport systems
Death of individual branches or the whole tree

What to do: Compare your tree to the same species nearby. If neighbors’ trees are two or more weeks ahead in development, schedule an arborist evaluation. Some trees naturally leaf out later (oaks, walnuts, ashes), so species comparison matters.

Why timing matters: If the problem is localized branch death, prompt pruning prevents decay from spreading. If it’s systemic disease, early diagnosis improves treatment options. If the tree has died, removal before it destabilizes prevents emergency situations.

Fungal Growth at the Base or on the Trunk

Mushrooms appearing around your tree's base or shelf-like brackets (conks) growing from the trunk signal decay organisms at work inside the tree.

What fungal growth indicates:

Root decay compromising the tree’s anchor system
Internal trunk rot hollowing the structural core
Advanced decline that may have been progressing for years

Not all fungi harm trees—some form beneficial relationships with roots. But conspicuous mushroom clusters or woody conks warrant professional assessment to determine whether the decay threatens structural stability.

What to do: Don’t remove the fungi; they’re symptoms, not the problem. Photograph them for reference and call an arborist. Decay evaluation sometimes requires specialized tools (resistance drilling, sonic tomography) to assess how much sound wood remains.

Why timing matters: Trees with significant internal decay can fail without warning. Spring assessment—before summer storms and before decay progresses further—gives you the most options.

Bark Falling Off in Large Sections

Some bark shedding is normal. Maples, sycamores, and birches naturally shed outer bark as they grow. But large sections of bark separating from the trunk—especially if the wood underneath appears dark, dried, or damaged—indicates serious problems.

What abnormal bark loss indicates:

Frost cracks from winter freeze-thaw cycles
Sunscald damage on south-facing trunk surfaces
Disease affecting the cambium layer
Physical damage from equipment, vehicles, or animals
Decline or death of trunk sections

What to do: Examine the exposed wood. Healthy wood appears light-colored and moist. Dark, dry, or crumbly wood indicates damage or death of that trunk section. If damage wraps more than 25-30% around the trunk’s circumference, the tree’s long-term survival is questionable.

Why timing matters: Bark damage exposes trees to secondary infections and pest invasion. Professional assessment determines whether the tree can compartmentalize the wound and survive, or whether removal is the safer choice.

Leaning That Wasn't There Before

Trees don't develop sudden lean without cause. If a tree that stood straight now angles to one side—even slightly—root failure may be underway.

What new lean indicates:

Root breakage from wind, saturated soil, or decay
Root plate lifting on the side opposite the lean
Progressive failure that will continue until the tree falls

What to look for: Check the soil around the trunk base on the side opposite the lean. Heaving, cracking, or lifted soil confirms root plate movement. This tree is actively failing and may come down in the next wind event.

What to do: Keep people and vehicles away from the tree’s fall zone (the area where it would land if it fell in any direction). Call for emergency assessment. Do not wait.

Why timing matters: Leaning trees rarely straighten themselves. Most progressive leans end in failure. The question is whether failure happens on your terms (controlled removal) or the tree’s terms (uncontrolled fall, potentially onto your house, car, or family).

Cracks in the Trunk or Major Branches

Cracks indicate structural failure in progress. Unlike surface bark splits from rapid growth, deep cracks extending into the wood compromise the tree's ability to support its own weight.

Types of cracks to watch:

Vertical cracks running up the trunk suggest internal stress or frost damage
Horizontal cracks indicate shear stress and imminent failure risk
Cracks at branch unions show attachment points separating
Cracks with oozing sap or sawdust may indicate boring insects compounding structural problems

What to do: Cracks don’t heal—they can only be managed. Professional assessment determines whether cabling, bracing, or load reduction can extend the tree’s safe life, or whether the crack creates unacceptable failure risk.

Why timing matters: Cracks propagate under stress. Each wind event, heavy rain, or ice loading extends them. Addressing cracks before spring storms test them provides more options than emergency response after partial failure.

Dead Branches Throughout the Canopy

A few dead twigs are normal. Clusters of dead branches scattered throughout the crown—especially if they're progressively increasing—signal systemic decline.

What scattered deadwood indicates:

Root problems limiting water and nutrient supply
Vascular disease blocking internal transport
Environmental stress beyond the tree’s recovery capacity
Boring insects disrupting vascular tissue
Advanced decline that may not be reversible

What to do: Estimate what percentage of the canopy is dead. Less than 25% dead with healthy new growth elsewhere suggests the tree is managing stress and may recover with support. More than 50% dead indicates severe decline requiring evaluation. Dead branches should be removed regardless—they pose falling hazards.

Why timing matters: Spring reveals true canopy condition as healthy branches leaf out while dead branches remain bare. This window allows accurate assessment before summer foliage obscures the picture.

Unusual Spots, Growths, or Discoloration on Leaves

Early spring leaf emergence should produce healthy, consistently colored foliage. Spots, unusual colors, distorted growth, or powdery coatings on new leaves indicate disease or pest activity.

Common spring leaf problems in Clark County:

Anthracnose causes brown spots and distorted leaves on maples, oaks, and dogwoods
Apple scab produces olive-brown spots on apple and crabapple leaves
Powdery mildew coats leaves with white powdery residue
Aphids cause curled, sticky leaves and attract secondary pests
Leaf miners create winding trails visible within leaves

What to do: Many leaf diseases are primarily cosmetic and don’t threaten tree survival. Others require treatment to prevent progressive damage. Professional diagnosis identifies the specific problem and whether treatment is warranted.

Why timing matters: Most foliar diseases and pests are easier to manage early in the infection cycle. Waiting until severe symptoms appear limits treatment effectiveness.

When One Sign Is Enough to Call

Some situations demand immediate professional attention regardless of other factors

When to Call:

Any lean toward structures, vehicles, or high-traffic areas
Cracks in the trunk or major branch unions
Large fungal conks on the trunk
Trees that have dropped major branches
Any tree that makes you uneasy

Trust your instincts. If something seems wrong, it probably is. The cost of professional assessment is minimal compared to the cost of property damage, injury, or losing a tree that proper care could have saved.

What Happens During a Professional Tree Assessment

Understanding the process helps you know what to expect and what questions to ask.

Visual Inspection

The arborist examines the tree from the ground, evaluating structure, crown condition, trunk integrity, and root zone indicators.

Diagnostic Tools

For suspected internal decay or root problems, arborists may use specialized tools—resistance drills, sonic tomographs, or root excavation—to assess conditions invisible from outside.

Risk Evaluation

Based on findings, the arborist assesses failure probability and potential consequences if failure occurs.

Recommendations

You’ll receive clear options: monitoring, treatment, pruning, structural support, or removal—with rationale for each recommendation.

Written Report

For significant concerns, request a written assessment documenting findings and recommendations. This documentation proves valuable for insurance purposes and future reference.

Tree Assessment FAQs

How much does a tree assessment cost?

At Ohana Tree Care, initial consultations and estimates are provided at no charge. We’ll evaluate your trees, discuss concerns, and provide recommendations without obligation.

How often should I have my trees professionally assessed?

For most properties, professional assessment every 2-3 years is appropriate. Trees near structures, mature trees, or trees with known issues may warrant annual evaluation.

Can a declining tree be saved?

Often, yes. Early intervention improves outcomes significantly. Treatments may include soil improvement, targeted pruning, pest management, or structural support. But some decline is irreversible—honest assessment tells you which situation you’re facing.

Should I be present during the assessment?

Ideally, yes. Walking the property together allows you to point out specific concerns and ask questions in real time. You’ll better understand findings and recommendations.

What if the arborist recommends removal but I want to keep the tree?

A reputable arborist explains why removal is recommended and what risks retention involves. Ultimately, it’s your decision—but you should make it with full information about potential consequences.

Do I need an arborist, or will any tree service work?

For basic tasks like small branch pruning, any competent tree service may suffice. For health assessment, diagnosis, or decisions about valuable or potentially hazardous trees, ISA-certified arborists provide expertise that general tree workers typically lack.
