Trees get sick for many reasons: fungi, bacteria, insects, poor soil or a run of hot, dry years that leaves them too weak to fight back. Longmont Tree Company diagnoses and treats tree diseases and pests for homes, HOAs and commercial properties across Longmont. The goal is to save trees that can be saved, protect the healthy trees around them and be honest about the ones that can't.
Treatment only works when it matches the problem, so we start by finding out what's really going on. Then we choose the treatment, timing and method that fit the tree, whether that's a trunk injection, a soil treatment, pruning out infected wood or improving the conditions the tree is growing in.
Many treatments work best at a particular time of year, so it pays to call as soon as you notice a problem.
Tree Disease and Pest Treatment Services in Longmont
Most tree health problems fall into one of four groups. Many trees have more than one going on at once, so we treat the whole picture. We'll explain what we found in plain language before recommending anything.
Fungal Disease Management
Fungi cause leaf spots, cankers, wilts, needle cast and root and trunk rot. Some, like many leaf spots, look bad but do little harm. Others can kill a tree. We identify the disease, prune out infected wood with sterilized tools, and apply fungicide when it will actually help. Around Longmont we watch for canker on honeylocust, fire blight on crabapples and pears, and needle cast on spruce.
Insect and Pest Control
Borers, scale insects, aphids, mites and beetles weaken trees and spread disease. Emerald ash borer has been in Longmont since 2016, and the City of Longmont says untreated ash trees will die from it. Systemic trunk injections can protect a healthy ash for about two years per treatment. Store-bought products only work on small ash; bigger trees need a licensed applicator. For other pests, we often start with the least disruptive option that will work.
Nutrient Deficiency Correction
Yellow leaves with green veins, stunted growth and early leaf drop often point to a nutrient problem rather than a disease. Iron chlorosis is common in alkaline soils. We confirm the cause with a soil test and correct it with targeted treatments or tree fertilization.
Preventive Treatments
For high-value trees at risk from a pest or disease that's active in the area, prevention costs much less than treatment or removal. We set up a treatment schedule based on the threat, the tree and its value to you. We only recommend prevention when there's a real, nearby threat to that kind of tree.
Our Tree Disease Treatment Process
Treating the wrong problem wastes money and time the tree may not have. Here's how we make sure the treatment fits. It also keeps you from paying for treatments a tree doesn't need.
Consultation and First Look
We ask what you've noticed and when, then look closely at the tree: leaves, twigs, bark, trunk and roots. We also check nearby trees of the same species, which helps tell a spreading disease from a local problem.
Diagnosing the Disease or Pest
We identify the likely cause from the signs and symptoms. When it's not clear, we take samples for lab testing and tell you the cost before sending them. A firm diagnosis comes before any treatment. Guessing leads to the wrong product, wasted money and lost time.
A Treatment Plan for Your Tree
We explain the options, how likely each one is to work, how long it takes and what it costs. Sometimes the honest answer is that removal makes more sense. You choose, with the plan and price in writing.
Applying the Treatment
Treatments are applied at the right time and dose, using methods that keep products on the tree and out of the wider environment. Trunk injections, soil drenches and targeted sprays each have their place. Infected wood is pruned out and taken away. We'll tell you about any precautions, such as keeping pets off treated soil for a while. On city-owned street trees, Longmont allows plant health care only with a permit and a state-licensed company, and it doesn't allow soil injections or aerial sprays.
Monitoring and Adjusting
We check back to see how the tree is responding. New leaves, better color and less dieback are good signs. If things aren't improving, we adjust the plan rather than repeating something that isn't working.
Aftercare and Recommendations
Healthy trees fight off disease better, so we'll recommend watering, mulching and soil care to keep the tree strong. We'll also tell you when follow-up treatments are due and what signs to watch for.

Tree Disease Treatment FAQs
Common questions about treating sick trees in Longmont. If your tree is showing new symptoms, call (303) 578-5969 sooner rather than later. We can often tell a lot from a few clear photos.
How much does tree disease treatment cost in Longmont, CO?
Single treatments usually cost about $150 to $500 per tree, depending on the tree's size and the treatment. Emerald ash borer injections are priced by trunk diameter. Ongoing programs cost more but are often much cheaper than removal and replanting. You'll get a written price before any treatment.
What are the most common tree diseases and pests in Longmont?
These are the problems we see most around Longmont:
- Emerald ash borer in ash trees
- Iron chlorosis (yellow leaves) on trees in alkaline soil
- Canker disease on honeylocust
- Fire blight on crabapples and pears
- Tussock moth on large blue spruce
- Nipple gall on hackberry, which looks bad but is cosmetic
Do you treat emerald ash borer?
Yes. If a neighbor asked whether to treat an ash or take it down, the first thing we'd say is: let's take a look before you spend any money. If it's healthy and giving you good shade, treatment may be worth it. If it's badly declining or has serious structural problems, removal might make more sense. Either way, know that treatment is an ongoing commitment. Healthy ash trees with less than about a third of the canopy lost can usually be protected with trunk injections every one to two years. Trees with more damage than that rarely recover, and we'll recommend removal before they become brittle and hazardous. If you have ash trees and EAB has been found nearby, it's worth having them checked now rather than waiting for symptoms.
Can a diseased tree be saved, or does it need to come down?
It depends on the disease, how far it has spread and the tree's overall health. Many trees recover well with treatment and better care. Trees with advanced decay in the trunk or roots, or most of the crown dead, usually can't be saved safely. We'll give you an honest view before you spend money on treatment.
How long does tree disease treatment take to work?
Trunk injections usually move through the tree within a few weeks, but visible improvement often takes until the next growing season. Soil and nutrient treatments can take a season or two. Recovery is gradual, and the tree may still look rough for a while before new growth shows the treatment is working. We'll check back and tell you how it's going.
