Half the crown leafed out in April and half of it never did. Or the ash has gone thin at the top, or dense green clumps are hanging in a cottonwood that is otherwise bare in February, or mushrooms came up at the root flare after the monsoon and have bothered you ever since. Underneath all of it sits one question: is my tree dying? A tree health assessment in Albuquerque answers that before anyone hands you a quote to take it out. Roque Tree Service LLC has spent since 2015 trimming, removing — and just as often not removing — trees across Bernalillo County and the valley, and this visit is what most people mean when they go looking for a tree doctor in Albuquerque: someone who has worked these trees for 11 years walks yours, says plainly what is wrong, and puts it in writing. We are licensed, bonded and insured under NM license #L1313927408, and the look is part of a free estimate.
Signs Something Is Wrong With Your Tree
Trees decline slowly and then fail all at once. These are the symptoms that bring people here, and what each one usually turns out to mean.
Thin, late or one-sided leaf-out. A tree that leafed on some limbs and not others is showing you where the damage sits. Bare twigs at the top and the outer tips, working inward, is the classic drought and root pattern on cottonwood, ash and globe willow.
Bark falling off my tree. Sheets or plates shedding from the trunk almost always mean the wood beneath is already dead. What counts is what is under it: round or oval exit holes with sawdust-like frass point to cottonwood borer or lilac-ash borer, and a column of woodpecker holes means the bird found beetles before you did.
Mistletoe in cottonwood trees. In a bare winter crown the clumps are unmistakable — dense green balls forty feet up. Broadleaf mistletoe is spreading further north along the Rio Grande each year, and on an old tree it often gets blamed for a decline that is really age plus water.
Mushrooms, conks or shelf fungus low on the trunk. Fruiting bodies at the base mean decay in the structural wood — the kind of failure that takes a whole tree over instead of shedding one limb.
A Siberian elm brown by midsummer. Elm leaf beetle, and it looks far worse than it is on an irrigated tree: here is how to tell beetle damage from real decline.
Yellow leaves with green veins on a maple, sycamore, oak or fruit tree is iron chlorosis on alkaline soil, not a disease. Sawdust, pitch tubes and needles going red from the tips on a piñon or pine is Ips. A new lean with cracked or mounded soil on the far side of the trunk is the root plate moving.
One sign is worth a look. Two or more, park the car elsewhere and keep the kids off that side of the yard until it is sorted out — our full guide to the signs of a dying tree covers the rest.
What a Tree Inspection Covers, Root Flare to Crown
A useful tree inspection starts with history, not with the leaves. When did you first notice it, and what changed in the last two or three years — sprinklers shut off in a xeriscape conversion, a trench cut for a driveway or gas line, a wall built over the roots, a hard windstorm, a dry winter?
Then the tree, bottom to top. At the base: buried or girdling roots, fungus, drip emitters sitting against the trunk, soil heaved on the side away from a lean. On the trunk: cracks, cankers, cavities, exit holes and frass, sunscald on the southwest face, included bark where two leaders meet. In the crown: how the dieback is distributed, how much deadwood there is, mistletoe, and epicormic sprouts, which are a stressed tree growing leaves wherever it still can. Last comes what a failure would hit — a hollow trunk in a pasture is a wildlife tree; the same trunk twelve feet from a bedroom is a decision.
There are honest limits to what anyone settles from the ground. Some root diseases and pathogens need a sample, and that goes to the NMSU Bernalillo County Cooperative Extension office on Menaul Boulevard NW. When that is the next step, we say so, because guessing at it is worth nothing to you.
What Is Stressing Albuquerque Trees Right Now
Nearly every tree we look at in this metro traces back to one of six things.
Drought, first and biggest. A high-desert city that averages under nine inches of rain a year just came through the driest stretch on record: extreme-to-exceptional drought in 2025–26, the Rio Grande dry at Central Avenue for 58-plus days by mid-August 2026, roughly 1,000 acres of bosque browning out in weeks. Every yard tree off the valley floor lives on drip or bubblers, so drought stressed trees here are usually irrigation stories — most often a lawn turned to gravel with the old sprinklers capped, which starves a 60-year-old elm, ash or cottonwood slowly enough that nobody connects the two events. Tip dieback comes first; borers come second. Where a tree has to be replanted, the Treebate palette — honey locust, Chinese pistache, desert willow — is what the city rebates.
Cottonwoods running out of time. Most of the giants on valley lots came up after the 1941 flood, which puts the cohort at 80 to 100 years old, the far end of the species' lifespan here, over an aquifer that keeps dropping. Top dieback and still-day limb drop in the North Valley, Los Ranchos, Corrales and Old Town is age and water more often than any single pest, with mistletoe along for the ride. Sometimes the honest finding is that a tree has reached the end and belongs on the removal schedule instead of a watering plan.
Elm leaf beetle and elm seed bug on the Dust Bowl-era Siberian elms that shade Ridgecrest, Nob Hill and the older valley streets: ugly, survivable on a watered tree, serious on a dry one.
Borers in already-stressed hosts — cottonwood borer, lilac-ash borer, locust borer. NMSU's guidance is to take dead cottonwood limbs off in winter or early spring, while the adults are inactive.
Ips and twig beetles in piñon and pine on foothills, Volcano Cliffs, Placitas and East Mountain lots after a dry winter. Needles going red from the tips usually mean that tree is already gone.
Iron chlorosis on our alkaline basin soils, roughly pH 7.5 to 8.5 — the yellow-leaf, green-vein pattern on maples, sycamores, oaks and fruit trees. Chronic rather than fatal.
One pest we will not blame: emerald ash borer is not confirmed anywhere in New Mexico, and the nearest known population sits in northern Colorado. Ash is a big share of 1970s–90s plantings here, so it is worth watching for — and it is not what is wrong with your ash today.
Keep It, Prune It, or Take It Down
Every assessment ends in one of four places.
Keep it and water it right. Plenty of worrying trees need nothing but deep, slow water out at the drip line instead of at the trunk, mulch pulled back off the root flare, and another look in October when the dieback is easy to count.
Prune it. Deadwood, a borer-weakened limb, a mistletoe-heavy branch, a storm crack — a properly placed cut takes the hazard out and keeps the tree. That is tree trimming work, and it is the most common outcome of these visits.
Take it down. Advanced decay at the base, a crown more dead than alive, a hollow cottonwood over the house, a red piñon, a fresh lean with the root plate lifting. Some trees are past the point where any cut helps.
Get it tested, or get a formal report. When the answer needs a lab or a credentialed specialist's paperwork, we say that instead of inventing a diagnosis.
One local wrinkle before you decide: if the tree that has to go is a mulberry, a Siberian elm or a male juniper, the 1994 Pollen Control Ordinance means you cannot replant it in kind. The tree you have is grandfathered; its replacement will be a different species — a good reason to get the keep-or-remove decision right the first time. And if a limb is already hanging or on the ground, that is not an assessment, it is 24/7 emergency service: call (505) 306-2007 and tell us what came down, and we head out within about an hour, depending on distance.
What an Assessment Is — and What It Isn't
Plainly: we are a licensed, bonded and insured tree crew that has been reading Albuquerque trees for 11 years, across more than 1,000 projects. What you get is an experienced on-site inspection and written findings in language you can use.
What it is not is a formal report from a credentialed tree specialist. Some HOA architectural boards, the Village of Corrales Landmark Tree process, a City Forester right-of-way question or a legal dispute may require one, and we would rather tell you that up front than hand you paperwork that will not hold. It is also not a treatment program — we do not spray, inject or fertilize, and if a beetle or borer problem calls for a systemic product, that is a licensed applicator's job.
Trees We Look At Across the Valley and the Heights
Home base is the Southeast Heights, and the crews work outward from there. Around Albuquerque that means tired elms in Ridgecrest and the SE Heights, ash and mulberry through the International District and Uptown, and young Treebate plantings on the Westside mesa. In the North Valley and Los Ranchos it is the 1941-cohort cottonwoods over lanes, acequias and pasture, with mistletoe in most of them. In Corrales it is cottonwood decline on Landmark-designated trees and along the ditch banks. Placitas brings us dead piñon; the far side of the river brings us pines struggling in sand.
Before You Take a Tree Down, Get a Second Look
Eleven years in business, more than 1,000 customers served, our own crews on every job — and we would still rather tell you a tree can stay than sell you a removal you did not need. If you have been watching something in the yard and cannot tell whether it is dying or just thirsty, send two or three photos — the whole tree, the base of the trunk, the worst limb — through the Get Free Estimate form, and you will get a straight read on what is wrong and what, if anything, needs to happen next.
