Can this tree be saved?
Sometimes. Start with the cause of decline and the tree's remaining structure, not a removal quote. Brown leaves alone do not identify a disease or decide whether a tree can stay. [1020] [1032]

What a year of care looks like.
Most of the work happens below ground, in the soil the roots live in. Here it is, one step at a time.
A year of care, step by step.
Most of the work happens below ground, in the soil the roots live in. Press play, or pick a step.
Start at the soil line.
Two things we look for first: mulch piled against the trunk, and soil packed hard by mowers, cars and feet.
Uncover the root flare.
Compressed air blows the soil away without cutting roots. A root wrapping the trunk can be cut free, if that is safe for the tree.
Loosen packed soil.
We open channels in the packed soil with air and work in compost, so new roots have somewhere to grow.
Test before adding anything.
A soil test shows the pH and nutrients, and it decides what, if anything, the tree needs.
Add only what is short.
Many trees need no fertilizer at all. If the test shows a shortfall, we add only what is missing.
Mulch wide, water deep.
Two to four inches of mulch, as wide as you will allow, kept off the trunk. In dry spells, a slow, deep soak.
Come back every year.
We check the tree top to bottom once a year and leave a written report, so small changes get caught early.
We favor keeping a tree when its condition and location support that choice.
Start with diagnosis, then risk
Ask what changed, when symptoms began and whether the roots, trunk or major limbs are damaged. Record recent drought, construction and storm damage. An assessment should distinguish tree health from the risk of a part failing. MU Extension's storm guidance considers vigor, major limb damage and the remaining crown rather than appearance alone.

Hypoxylon canker in stressed Tennessee oaks
Tennessee Forestry describes hypoxylon canker as a secondary disease affecting severely stressed hardwoods. It is common after prolonged severe drought. Bark may shed over spore-bearing mats, and few management options are available. Those signs deserve a prompt assessment, not a promise that feeding will fix the tree. [1019]
Bacterial leaf scorch can resemble drought
Tennessee Forestry says bacterial leaf scorch can be difficult to diagnose because symptoms resemble drought and other vascular problems. It lists no effective treatments. A photograph of brown leaf edges is not enough to make the diagnosis. Ask about diagnostic confirmation before deciding what to do next. [1020]
Crape myrtle bark scale is not an automatic removal
UT Gardens describes white, felt-like patches on bark, often near branch joints, with black sooty mold as infestation increases. The pest can reduce vigor and flowering without necessarily killing an otherwise healthy plant. Get the cause confirmed. This guide does not offer pesticide application or prescribe a product. [1026]
Oak wilt depends on location
MU Extension describes oak wilt as widespread in Missouri. Tennessee Forestry reports past detections, no recent detections and no establishment across the state. Neither statement diagnoses a particular oak. Suspected cases need professional confirmation and state-specific advice. [1009] [1008]
Yellow pin oak leaves can start with soil
MU's Green Horizons explains that pin oaks in alkaline soils can develop iron chlorosis and yellowish foliage. The site matters. Ask for soil assessment before adding amendments or fertilizer. Yellow leaves do not by themselves prove the tree is beyond care. [1016]
Ask for a reasoned choice
Request a written explanation of the likely cause, what remains uncertain and the options for keeping the tree. Ask what signs would change that recommendation. Removal may be appropriate for major structural damage, but it should not be the default response to every symptom. [1032]
Questions about this work
Can a photo settle the question?
A photo can document symptoms, but similar-looking problems can have different causes. Bacterial leaf scorch is one example where symptoms overlap with drought and other diseases. [1020]
