Tree Health Services in Northglenn, CO

Mature cottonwood leafing out in spring above a north metro backyard

Not every sick tree needs to come down. Some need a treatment, some need deadwood pruned out and a season to recover, and some are past saving and the kindest thing is a removal and a new tree in the right spot. Arbol De Fuego Services looks at the tree, tells you which of those it is, and handles the work across Northglenn and the north Denver metro.

Call (720) 210-3718 for a free look. We do not charge to walk the yard and give you a straight recommendation.

Emerald Ash Borer Treatment

Emerald ash borer has been confirmed in Westminster, Broomfield, and Thornton, and every ash in Northglenn is now in its path. The signs are a thinning crown that starts at the top, D shaped exit holes about an eighth of an inch across in the bark, S shaped tunnels under bark that is starting to split, and woodpecker damage where the birds are digging for larvae. An ash with early damage and most of its crown intact can be protected with trunk injections repeated every two to three years. That treatment requires a Colorado commercial pesticide applicator license, so we coordinate it through a licensed applicator partner we have referred customers to before, and we handle the assessment, any deadwood pruning, and the removal if the tree is too far gone. If more than a third of the crown is already dead, treatment rarely pays off and we will tell you so. See ash tree removal for what that looks like.

Insect and Disease Treatment

Ash borer is the headline, but the north metro has other problems that take trees: Cytospora canker on blue spruce, which shows as dead branches from the bottom up and resin bleeding on the trunk; ips beetles in stressed pines; fire blight on crab apples and ornamental pears, where shoots blacken and curl like a shepherd’s crook; and drought stress that opens the door to all of it. Our part of the job is the diagnosis and the cutting: pruning out cankered limbs and fire blight strikes with sterilized tools, removing deadwood that is harboring beetles, and taking the whole tree if it is beyond help. Where a spray or injection is the right answer, we bring in a licensed applicator rather than guess with a product from the hardware store. Call us before you spend money on a treatment that will not fix the problem.

Tree Planting

The natural follow on to a removal is a new tree, and the right choice planted the right way will outlive the mistakes that got the last one taken down. We plant balled and burlapped and container trees, set at the correct depth with the root flare visible, staked only if the site needs it, mulched in a wide ring that stays off the trunk, and watered in. For Northglenn’s clay soil, dry summers, and wet spring snow, we lean toward Kentucky coffeetree, hackberry, bur oak, honeylocust, and catalpa for shade, and serviceberry or hawthorn for tight yards, and we steer people away from ash, silver maple, and Siberian elm. Fall and spring are the best planting windows. Customers have used us to plant, trim, and remove over multiple seasons, and planting is where a long relationship with a yard usually starts. Ask us to add a replacement tree to any removal quote.

How a Tree Health Visit Works

  1. You call or text with what you are seeing. A photo of the leaves, bark, or the whole tree helps.
  2. We come out, look at the tree, and tell you what it is: a treatable problem, a pruning job, a watering problem, or a removal.
  3. You get a written quote for any cutting or planting work. Treatment pricing comes through the licensed applicator.
  4. We do the tree work, coordinate the treatment if there is one, and tell you what to watch for next season.

Signs Your Tree Needs a Look

Tree Health Services Questions

Do you do the chemical treatments yourselves?

Trunk injections and spraying in Colorado require a commercial pesticide applicator license. We assess the tree, handle all of the cutting and cleanup work, and coordinate the treatment itself through a licensed applicator partner we have worked with on customer jobs. You get one point of contact either way.

Can my ash tree be saved?

If it still has most of its canopy and the borer damage is early, often yes, with injections repeated on a schedule. If it has lost more than about a third of the crown, the honest answer is usually removal. We will tell you which one it is after we look.

What trees do you recommend planting in Northglenn?

Trees that handle clay soil, dry summers, and wet spring snow: Kentucky coffeetree, hackberry, bur oak, honeylocust, catalpa, and for smaller yards, serviceberry or hawthorn. We steer people away from ash, silver maple, and Siberian elm. We can plant what you pick or bring options to the estimate.

When is the best time to plant a tree in Colorado?

Spring after the last hard freeze, or early fall, September into early October, so roots get established before winter. Summer planting works if you commit to watering.

What does a tree health visit cost?

The look and the written recommendation are free. Pruning, deadwood removal, planting, and removal are quoted in writing on site. Treatment pricing comes from the licensed applicator and we pass it through.
