Our Approach

Understanding Tree Health & Disease Care

Every tree is a living system, and like any living thing it can fall victim to disease, pests, and environmental pressure. Tree health care is the practice of catching those problems early, treating them correctly, and preventing them from returning — before a treatable issue turns into a removal.

At Crown & Branch Tree Service, every visit starts with a hands-on diagnostic review from one of our ISA-certified arborists. A tree's bark, foliage, root flare, and overall shape all carry information about what's happening beneath the surface. Our team is trained to read those signals accurately, catching everything from fungal and bacterial infections to nutrient gaps, root decay, and pest activity.

"The window for saving a tree is often narrower than people expect. Conditions like oak wilt or Dutch elm disease respond best when caught in their first season — delay is usually what turns a treatable tree into a lost one."

Our disease care covers the range of conditions we regularly encounter across Alpharetta, GA properties, including anthracnose, fire blight, powdery mildew, Phytophthora and Armillaria root rot, emerald ash borer infestation, scale insects, and a number of other fungal, bacterial, and pest-related threats.

No two treatment plans look alike — we account for tree species, how advanced the condition is, soil quality, and what's happening in the surrounding landscape. Wherever it makes sense, we lean on organic and low-impact treatment options to protect both your tree and the environment around it. Once a tree is back on track, our follow-up monitoring keeps it that way through regular seasonal check-ins.

Conditions We Commonly Treat

🍄
Oak Wilt
An aggressive fungal disease that clogs the tree's internal water and nutrient pathways, often leading to fast, visible crown decline.
🌿
Dutch Elm Disease
Carried by elm bark beetles, this fungal disease has wiped out entire elm populations. Fungicide injection early on can still turn things around.
🔥
Fire Blight
A bacterial issue frequently seen in apple, pear, and crabapple trees, leaving branches with a scorched look. Managed with careful pruning and systemic care.
🦠
Root Rot Complexes
Fungal pathogens living in the soil weaken root structure and nutrient absorption. We address this with soil remediation paired with targeted fungicides.
🐛
Emerald Ash Borer
This invasive beetle tunnels beneath ash bark, cutting off nutrient flow. We offer both preventative and curative systemic treatment options.
Spot the Warning Signs

How to Tell When a Tree Is Struggling

Trees give off warning signs well before a problem becomes critical — you just have to know what to look for. These are the indicators our arborists check on every single visit.

🍃
Off-Season Discoloration
Pale, yellow, or browning leaves outside of autumn can point to nutrient shortages, soil pH problems, or an infection beginning to move through the tree's vascular system.
🌰
Cankers and Bark Damage
Sunken or cracked patches on the bark are often a sign of canker disease. If ignored, cankers can eventually girdle a branch or the trunk itself.
🍂
Dieback From the Outside In
When branch tips start dying first and the damage works its way toward the trunk, it usually points to vascular disease, drought stress, or a pest issue disrupting water flow.
💧
Weeping or Oozing Bark
Sap or fluid coming from cracks or discolored spots may signal wetwood, hidden borer activity, or older damage that's since been colonized by secondary pathogens.
🦷
Small Holes and Sawdust Trails
Neat, round or D-shaped holes paired with fine sawdust are a reliable sign of boring beetle activity, including damaging pests like the emerald ash borer.
🌱
Weak or Missing Growth
A tree that skips its usual growth spurt or produces far fewer leaves than its neighbors is often dealing with root damage, compacted soil, or a chronic disease draining its energy.
🍄
Mushrooms or Shelf Fungi
Fungal growths at the base or along the trunk usually mean internal decay is already underway, as the fungus feeds on the tree's heartwood.
⚖️
New or Worsening Lean
A tree that starts leaning, especially alongside soil lifting near its base, may be losing root stability — a condition worth evaluating quickly for safety reasons.
How We Work

Our Step-by-Step Diagnostic Process

We follow a consistent, standards-based process for every assessment, so treatment decisions are grounded in evidence rather than assumptions.

📋
Getting the Full Picture
We start by talking through what you've noticed, when it started, and what's changed around the tree. That background shapes how we approach the rest of the visit.
🔍
On-Site Visual Inspection
Our arborist walks the entire tree — canopy, trunk, bark, root flare, and surrounding soil — looking for anything that points to stress, disease, pests, or structural risk.
🧪
Deeper Diagnostic Testing
If a visual check isn't enough, we'll pull soil or tissue samples, or use resistance drilling and sonic tomography to check internal wood condition and confirm what we're dealing with.
📊
Building a Treatment Plan
Once we have a confirmed diagnosis, we map out a plan covering application method, product choice, timing, and what results you can realistically expect, with every option explained clearly.
💉
Applying the Treatment
Depending on the diagnosis, that might mean trunk injections, soil treatments, foliar sprays, pruning out infected wood, or a systemic pest control program — all handled by trained professionals.
📅
Checking In Over Time
Healing takes time, so we schedule follow-up visits to track progress, fine-tune the treatment if needed, and confirm the tree is truly recovering before we close out the case.
Common Questions

Answers to What Alpharetta, GA Homeowners Ask Us Most

We hear this question often from Alpharetta, GA homeowners. Weather-related stress usually shows up as temporary leaf loss or mild discoloration that bounces back once conditions improve. Disease and pest damage tend to behave differently — they progress, spread across the canopy, or show up alongside other clues like bark lesions, fungal growth, or boreholes. If you're unsure, a professional assessment is the most reliable way to know for certain, and we offer these at an affordable rate throughout Alpharetta, GA.
It really comes down to the specific disease, the tree species, how far the problem has progressed, and how sound the tree's structure still is. Plenty of trees that look far gone can be brought back to health with the right treatment applied at the right stage. That said, some cases have progressed too far to safely treat, or the tree has become a genuine hazard where removal is the more responsible choice. We give straightforward recommendations based on what's actually best for your property, not on selling you a removal job.
It depends heavily on what we're treating. Foliar fungicides for conditions like powdery mildew or anthracnose often show improvement within two to four weeks. Trunk injections used for vascular diseases such as oak wilt can take a full growing season before you'll see meaningful crown recovery. Systemic treatments for pests like emerald ash borer typically need one to two seasons to fully break the infestation cycle. We'll walk you through a realistic timeline specific to your tree once we've confirmed the diagnosis.
Safety guides every treatment recommendation we make. We favor the least invasive, lowest-toxicity option that will still get the job done. Trunk injections deliver treatment straight into the tree's internal system, which practically eliminates any contact risk in your yard. When foliar or soil applications are necessary, we rely on EPA-registered products applied at label-compliant rates by licensed technicians, and we'll always tell you exactly when it's safe to return to normal outdoor activity.
It can, and often does. Disease can move between trees through insects, windborne spores, contaminated soil, shared root systems, or even pruning tools that weren't sanitized between cuts. That's exactly why a fast, accurate diagnosis matters — the moment we spot symptoms, we also check nearby trees for early warning signs and recommend protective treatment for valuable trees that are at risk simply due to proximity, even if they aren't showing symptoms yet.
Preventing a problem is almost always cheaper and easier than fixing one. For Alpharetta, GA properties, our preventative programs include yearly health checkups, deep root fertilization to boost soil nutrients and microbial life, seasonal fungicide applications during high-risk weather, systemic insect protection in areas where invasive pests are active, and soil aeration to relieve compaction and support root health. Every plan is built around the specific trees on your property — their species, age, and risk level.
It is. You can't fully separate soil health from tree health, so our enhanced assessments include testing for pH, nutrient levels, compaction, drainage, and the presence of beneficial mycorrhizal fungi. A surprising number of above-ground problems actually start below the soil line. Fixing a soil deficiency can lead to real, visible improvement in canopy density, overall vigor, and disease resistance — which makes soil testing one of the most useful tools we have.
Cost depends on the disease itself, the tree's size and species, the treatment method, and how many trees need care. A basic fungicide application on a small ornamental tree costs far less than a systemic injection program for a large, mature shade tree. Every diagnostic visit comes with a clear, itemized estimate so there are no surprises before you commit to treatment, and we offer bundled pricing for properties with multiple trees needing attention.
