Sick trees, straight answers

Tree disease treatment around Pittsburgh

Half the calls we get about a “dying” tree turn out to be a bad leaf year. The other half are real, and a few of those are already past saving. We look at the tree, name what’s actually wrong with it, and tell you which of those three it is before anybody sells you a treatment plan.

What’s actually killing trees in Western PA right now

Every region has its own short list of tree problems, and ours is easy to recite. Oak wilt moves through red oaks fast enough that a healthy tree can drop most of its leaves in a single summer. Emerald ash borer already went through and took nearly every untreated ash in Allegheny County. Spotted lanternfly is the newest arrival and the loudest one, mostly because it swarms. Anthracnose hits sycamores every wet spring and looks far worse than it is. Needle cast quietly browns out blue spruce from the inside, which is why so many yards around here have a spruce that’s green on top and bare below the knees.

Those are different problems with different endings, and lumping them together as “my tree is sick” is how people end up spending money on the wrong thing. A sycamore with anthracnose usually needs nothing but a dry June. A red oak with wilt needs a decision this week. Telling the two apart is the entire job, and it starts with somebody standing under the tree instead of matching a phone photo to a picture on the internet.

Oak wilt and the calendar rule nobody mentions

Oak wilt spreads through beetles that are drawn to fresh cuts, and through root grafts between neighboring oaks. That gives us one hard rule we do not bend: oaks get pruned in dormancy, roughly late fall through winter, and not in the spring or summer growing season. If you have an oak that needs work in July, it waits unless it’s an actual hazard. Cutting an oak in warm weather in a neighborhood with wilt nearby is how the disease gets an invitation.

When wilt is already in a tree, the honest range of options is narrow. Sanitation matters, so infected wood comes down and leaves the property rather than sitting in a pile spreading spores. Root graft disruption between an infected oak and its healthy neighbors can be worth doing on a property with several oaks. Chemical injection exists for high-value trees, and when that’s the right call we say so and point you to a licensed applicator, because we’re a tree crew, not a pesticide outfit, and we’re not going to pretend otherwise.

Ash, spruce, and the ones that are already decided

The ash situation in Pittsburgh is mostly aftermath now. Emerald ash borer arrived, the untreated ash died, and what we deal with today is standing dead wood. Dead ash gets brittle in a way that other dead trees don’t, which is why crews stop climbing them after a couple of years and why they need to come down while a takedown is still routine. If you have an ash that somehow made it, we’ll look at whether it’s a survivor worth protecting or a tree in the slow part of the same story.

Blue spruce is the other one we get asked about constantly. Needle cast fungus infects new growth, browns it out a year later, and works its way up the tree while the top still looks fine. Improving airflow, cleaning up fallen needles, and being realistic about a species that never loved our humidity buys some trees years. A spruce that’s bare to the halfway point is usually telling you it’s done, and replacing it beats nursing it. That’s not the answer people hope for, but it’s the one that saves money.

What we do and don’t do

We diagnose, prune out infection, remove dead and dying wood, haul infected material off site, and time the work around each species. We refer chemical injection work to licensed applicators when a tree earns it.

The assessment side lives on the tree health page. If the answer turns out to be a takedown, that’s tree removal. See recent work in the gallery.

Triage, in the order it happens

Diagnosis first, then a decision you get to make with real information.

Your part

Tell us what you noticed and when. Leaves browning in July reads completely differently from leaves browning in September. Photos from the past couple of seasons help more than people expect. Then let us on the property to look at the whole tree, including the base and the soil around it.

If a neighbor lost the same species recently, mention it. That single detail solves a lot of oak questions.

Our part

Read the tree from the roots up: canopy thinning pattern, leaf and needle symptoms, bark condition, borer exit holes, egg masses, dieback direction. Name the problem or say plainly that we can’t be certain from the ground. Then lay out the options: treat, manage, or remove, with the honest odds on each.

Work follows the calendar. Oaks in dormancy, infected wood off the property, and no cuts that hand a disease a fresh doorway. Get a number up front before anything starts.

Neighborhood by neighborhood, the problem changes

Older streets in Penn Hills still carry a lot of mature red and pin oak, so wilt questions and dormant-season pruning schedules come up there more than anywhere else we work. The hillside lots in Shaler Township hold moisture at the bottom of the slope, and that’s where needle cast on spruce and anthracnose on sycamore show up first every wet spring. Out toward Moon Township, we’re still clearing dead ash from properties that lost several at once, because a stand that all died in the same year now needs to come down in the same few years.

Spotted lanternfly is everywhere at this point, and the honest news is that it kills far fewer trees than the panic suggests. It hammers grapes and it loves tree of heaven, which is itself an invasive worth cutting out of a fence line. On a healthy maple, lanternfly is mostly a nuisance and a sticky mess. Pulling the tree of heaven off your property does more real good than spraying every trunk in the yard, and we’ll say that even though it’s the smaller job.

Sick tree questions

The ones we answer standing in the yard, week after week.

My oak’s leaves browned in July. Is that oak wilt?

Maybe, and the timing is the reason to take it seriously. Wilt typically browns leaves from the outer canopy inward during the growing season, and a red oak can lose most of its canopy in weeks. Scorch and drought damage look similar but move slower and follow the weather. We come look, and if it’s wilt we talk about the neighboring oaks too, because root grafts carry it next door.

Is my ash tree saveable?

Usually not, if it hasn’t been treated. Emerald ash borer already moved through this area and most untreated ash are dead or dying. A tree with heavy upper dieback, woodpecker damage, and D-shaped exit holes is finished. A genuinely healthy ash that survived is worth a real conversation about protecting it. Either way, dead ash gets brittle fast, so it’s better to deal with it early than to pay for a harder takedown later.

Why is my blue spruce brown at the bottom?

Almost always needle cast, a fungus that infects new needles and browns them the following year, working upward while the top still looks healthy. Better airflow, cleaning up infected needles, and thinning crowded plantings can slow it. If the tree is bare past the halfway point, it’s not coming back, and a different species in that spot will make you happier in five years.

Do I need to do something about spotted lanternfly?

Less than the internet suggests. Lanternfly rarely kills established shade trees, though the honeydew and sooty mold it leaves behind make a real mess of decks and cars. The one thing worth doing is removing tree of heaven from your property, since that’s their favorite host and a magnet for the whole population. Scrape egg masses in winter and skip the trunk-spraying panic.

When does treating actually beat removing?

When the tree still has a solid structure, the problem is caught early, and the tree is worth the ongoing cost, meaning a specimen shade tree over your house rather than a crowded volunteer at the fence line. Once decay is in the trunk or major limbs, or the canopy is more than about half gone, treatment is buying time on a tree that’s already coming down. We say which one you’re looking at instead of selling the service with the bigger ticket.

What does disease work cost?

It depends entirely on what the tree has and what it needs, which is why we don’t guess over the phone. Diagnosis, sanitation pruning, and removal are three different jobs with three different numbers. Chris walks the property, tells you what’s wrong, and hands you an up-front number in writing for whatever you decide to do. Set up a visit and you’ll have it in a day or two.

Find out what’s wrong before you spend a dollar

One call, one walk-around, and a real name for whatever your tree has. If it can be treated we’ll treat it, if it can be managed we’ll show you how, and if it’s done we’ll tell you that too. One and done, in sawdust we trust.
