How To Care for Colorado Trees

While some may not think it, making sure your trees are properly healthy can be an arduous task. But our arborists here at ArborScape are here to show you how to care for Colorado trees so you can enjoy the benefits all year long.

Most of our services focus on tree trimming and removal, but we also have additional tree care services that we offer as routine maintenance so your trees can stay healthy as they grow throughout the seasons in our persnickety landscape.

ArborScape has been in business for over 25 years, and our certified arborists have a combined six decades of experience in the field and the region, so they’re able to come up with a treatment plan specifically designed to show you how to care for Colorado trees.

Care for Colorado Trees

Ash Tree Care

Ash trees can live up to 70 years here in Colorado with the proper care. However, that care can cost upwards of thousands of dollars just to protect it from its most problematic pest, the infamous emerald ash borer.

First discovered in Colorado in 2013, we’ve seen a massive spread of these borers into Littleton this past year. They’re known to spread quickly, and with ash trees making up 15% of Denver’s urban forestry, this could pose a huge problem without the proper treatments.

You’ll know your ash tree has borers when you start to notice branches without any leaves, especially toward the top; vertical splits in the bark that expose s-shaped tunnels, or d-shaped exit holes.

Luckily, we have those treatments to help mitigate the issues that the EAB can cause, such as an annual bark spray application in late spring or a trunk injection done every couple of years. Other fertilizers can help with overall health, but these treatments in particular will help control the emerald ash borer.

Aspen Tree Care

While aspens are very commonly found here in Denver, did you know that they shouldn’t be planted below 6,000 feet? This is why they require consistent maintenance here in order to grow sustainably.

One of the biggest things to keep an eye out for when it comes to aspen trees is leaf spot, a fungal disorder that can cause discoloration to the leaves. We recommend raking your leaves and fertilizing them to mitigate these issues.

We also recommend our general summer insect sprays to keep aphids from binging on these leaves.

Meanwhile, regular trimming of any dead or diseased branches also helps with regeneration and can slow disease cycles all while keeping your aspen healthy to enjoy the benefits of this classic Colorado tree.

Maple Tree Care

Did you know that Silver Maples and Autumn Blaze Maples are on Denver’s list of Prohibited Street Trees to plant? This is mostly because they have brittle branch structures that don’t do well in Denver’s climate.

However, regardless of what species of maple you may have, it’s important to know how to care for it.

Trimming is a bit different with maples. While it’s typically best to trim trees right before spring to encourage new growth, ArborScape’s team can trim and remove trees any season as long as the weather permits. But Maples should not be trimmed right before winter when it goes dormant.

Maples produce a lot of sap right before entering their dormant state, so trimming it then would cause the excess sap to rain down on sidewalks, houses, and cars come spring, which can cause a plethora of damage. Talk with our certified arborists to see when the right time is to trim your maple.

Pine Tree Care

With the array of pine species here in Colorado, it certainly doesn’t hurt to know how to care for these iconic evergreens.

We’ve talked at length about pine needle drop, but there are other seasonal issues to focus on as well, such as the IPS and mountain pine beetle that actively attack evergreens.

These beetles tend to attack stressed pines, so maintaining their overall health can help prevent an onslaught of future problems. We recommend watering your pines monthly to ensure the flow of nutrients, but sometimes this isn’t enough.

But don’t worry, we provide dormant oil and fertilization treatments to promote nutrients in the soil that the trees need. We also recommend our summer insect spray for your pines as aphid control.

And when it comes to trimming pines, they can be shaped but trimming these trees is usually done to remove dead or dying wood to give the tree the ability to use nutrients more efficiently toward natural growth rather than focusing on the wounds.
