If your tree is dropping leaves out of season, browning at the tips, growing fungus at the base, or bleeding sap down the trunk, it has a problem that will not fix itself.
Valley Tree Care diagnoses what is actually wrong, treats it, and comes back to confirm the treatment worked.

Seeing any of these? Call us and an arborist will tell you what it is.
Treatment without diagnosis is expensive guessing. Identical brown leaves can mean a fungal infection, a boring insect, root rot, or a broken irrigation line, and each one needs a different response.
Dieback patterns and where the thinning starts.
Cankers, bleeding, gumming, and borer holes.
Rot, drainage, and how wet the root zone actually is.
Over or under watering, which causes most of what we find.
Targeted applications, plus correcting the watering conditions that let the fungus take hold. Most fungal problems in the Valley trace back to overwatering, so treating the infection without fixing the irrigation just delays it.
Trunk injection or soil application, timed to the insect's life cycle so the treatment actually lands. Palo Verde borers will kill an otherwise healthy desert tree if left alone.
Aeration, soil amendment, and irrigation correction. Root rot is a drainage problem before it is a disease problem.
Sustained weather below 35 degrees or above 110 degrees causes burning and dieback on many Valley species. The recovery plan is pruning and support rather than chemical treatment.
We return at set intervals to check how the tree responded and adjust the plan. Treatment that nobody verifies is just a receipt.
Heart rot, also called frizzle top, shows up as new growth coming in badly stunted. Fusarium wilt shows as red or brown bleeding down the sides of the palm. Both need diagnosis early, because a palm does not heal wounds the way a tree does.
Fungus, usually caused by overwatering, leaves the fronds wilted and droopy.
Fungus that decays the lower growth and the trunk, plus frost and heat damage in extreme weather.
Root rot, almost always from overwatering.
Canker causes spotting and curling of the leaves. Gummosis kills back the trunk bark and often causes major sapping. A sick orange or lemon tree usually shows it in the leaves first, then the fruit.
Acacia, palo verde, mesquite, sumac, tipu, palo brea, sissoo, vitex, Texas mountain laurel, and Texas ebony are most often hit by root rot from overwatering, or by the Palo Verde borer, an insect that bores into the tree and kills it.
Fungal disease and parasites, usually introduced by infected pruning tools or blown in during storms, showing as large amounts of dieback in the foliage. These species also handle frost poorly and burn back below 35 degrees.
Give us a call. An arborist will tell you what it is and whether it needs treating now.
Often, yes. It depends on how much of the root system and canopy is still alive and what is causing the decline.
Nutrient deficiency, most pest infestations, and most fungal infections are treatable.
Advanced root rot and structural failure usually are not. An arborist can tell you which
situation you are in during a single visit, which is worth doing before you pay to remove a
tree that had years left in it. A mature shade tree takes about 20 years to replace, and
removing a dead one costs more than treating a sick one.
An arborist is a tree specialist, the same way a doctor is a people specialist. Homeowners search for a tree doctor near me because they want someone who can tell them what is actually wrong, not someone who quotes a removal. That is the job.
Valley Tree Care serves North Scottsdale and the surrounding Valley, including Phoenix, Tempe, Fountain Hills, Mesa, Chandler, Gilbert, Glendale, Peoria, and Surprise.
Thirst usually bounces back within a day or two of a deep watering. Disease looks different: leaf spots, cankers, sap or gum weeping from the trunk, dieback that starts in one section and spreads, or fungus growing at the base. If watering doesn't fix it, or you're seeing any of those signs, it's worth having an arborist take a look before it gets worse.
It depends on the disease. Fungal infections and some bacterial diseases can spread between trees through shared irrigation, contaminated pruning tools, or root contact, especially between trees of the same species planted close together. Boring insects can move from tree to tree as well, which is exactly why an accurate diagnosis matters before deciding what needs treating first.
Most fungal and bacterial treatments show visible improvement within a few weeks to a couple of months, though a stressed tree's canopy can take a full growing season to fully recover. Irrigation corrections tend to show results faster, since you're fixing the root cause instead of just treating a symptom. We schedule a follow-up visit to confirm the treatment actually worked, not just assume it did.
Cost depends on the tree's size, the disease, and how far it's progressed, so we don't quote pricing over the phone or without seeing the tree. A free evaluation gets you an accurate, written treatment plan and price before you commit to anything, and if the tree turns out to be healthy, that's what we'll tell you.
Some early-stage watering issues can be corrected on your own by adjusting your irrigation schedule. But most tree diseases need an accurate diagnosis first, since identical symptoms can point to a fungal infection, a boring insect, or a drainage problem, each needing a completely different treatment. Treating the wrong problem just wastes time while the tree keeps declining.
Not usually. Most fungal infections, pest infestations, and nutrient deficiencies are treatable if caught before they've done structural damage. Removal typically only comes up when the root system has failed or the tree's become a safety hazard, something an arborist can confirm in a single visit.
