ArborScape's Pest & Disease Management
A lush, healthy landscape can provide a diverse ecosystem in your yard, attracting all sorts of pollinators that aid in the spread of nutrients. But when your trees become stressed from various environmental factors, they become more susceptible to pests and diseases. That’s where ArborScape comes in. We offer timely tree spraying to target these pests and help mitigate disease so you can keep your trees healthy.
When you hire ArborScape, a certified arborist assesses your tree for pests and soil nutrient deficiencies and customizes a tree spraying program for optimal landscape appearance. Our technicians will monitor changes in canopy cover, bark and leaf appearance, and branch flexibility while quantifying progress through year-to-year apical growth, soil moisture measurement, and DBH growth to ensure our treatments are working properly.
Timing of treatment & application is extremely critical when it comes to insect control!
Arborscape offers detailed, timely tree spraying services for optimal tree health.
Disease Prevention & Tree Spraying
Tree Spraying
The most effective method in many cases is spraying the tree with pesticide or fungicide as a contact prevention or curative agent. Working to avoid pests and diseases will help protect your tree from chronic stress. Also, the right amount of water helps prevent drought.
Trunk & Soil Injections
Some insect and fungus problems occur deep within the cambium layers (the bark of the tree) and injections are the best option. Injections are also a good option if you have environmental concerns about pesticide spraying. Injections are handy as there is little chance of entering the ground water supply.

Common Pests Requiring Tree Spraying or Injections in Denver
- Emerald ash borer (EAB) Read More Here.
- Mountain pine beetle (MPB) – typically attacks weaker trees due to old age, crowding, drought, fire damage, etc.
- IPS bark beetle – also known as “engraver beetles” targeting pine & spruce trees.
- Spider mites – common plant pests most easily identified by flecking, discoloration, and scorching of leaves.
- Aphids – a very common insect present throughout the entire season.
- Borers – active in spring, usually in late April/May.
- Pine Zimmerman moth – has larvae that damage the tree by tunneling under the bark. They are identified by large masses of sap at the tree wounds and die-off at the very top.
- Scale: These can appear as immobile bumps on tree bark or leaves. They are parasites that suck the sap of trees, causing yellowing leaves and branch dieback.
Disease Prevention & Spraying
- Chlorosis: A condition where tree leaves turn yellow due to a lack of chlorophyll. We see this a lot in Denver due to lack of nutrients in the soil. Fertilizers and iron treatments are a good way to combat this.
- Dutch Elm Disease: A fungal infection spread by elm bark beetles and root grafting. If caught in time, the only “cure” is to prune out the infected areas before the fungus spreads to the trunk.
- Blight: While there is no cure once a tree is infested in blight, we are able to prune out the infected parts, and apply a cambistat treatment to delay tree growth, resulting in a slower spread of the fungus.
Deep Root Fertilization & Soil Nutrition
Maintaining adequate nutrient absorption can be challenging due to Denver’s arid climate and clay soils. ArborScape has solutions.
- Basal Bark Application: A Basal Bark Application is a great tree fertilizer because it quickly rejuvenates trees. EnviroTree, a patented plant food for the Rocky Mountain West, is sprayed directly onto the bark from 3 feet high to the soil. Due to its water-soluble nature, it is easily absorbed. It effectively reverses leaf yellowing and winter die-back caused by chlorosis.
- Soil Drench or Bark Injection: We recommend spring and fall fertilization using a soil injection. The chemical is put into the soil and then moves from the roots to the leaves through the tree blood system (cambium layer). A micro injection fertilization procedure injects chemicals directly into the tree by drilling holes through the bark. This means less chemical use and no run-off.
- Root Stimulator: Tree “fertilization” in the fall focuses more on root development rather than fertilizing compounds- specifically enhancing fine root hair growth. This is why you’ll often hear it referred to as a root stimulator as well. Unlike deep root fertilization, root stimulator applications minimize iron and nitrogen usage, as it’s crucial to restrict nitrogen to avoid disrupting the tree’s winter dormancy cycle.

FAQs ABOUT TREE SPRAYING
Trees are susceptible to pests and disease. Spraying your trees can help mitigate these issues. Spraying your trees can help protect them from borers, beetles, and general insects that can stress your tree, making it more prone to disease.
The Emerald Ash Borer is running rampant through Denver. Once infested, there is no saving your ash tree. Mountain Pine Beetles and Ips Beetles are also making their way across the Front Range and invading pines and spruces. ArborScape offers sprays and injections to prevent these issues.
For effective, long-term insect control for trees, a targeted tree spraying is one of the best lines of defense at stopping active pests from destroying your tree.
The timing for spraying trees for insects can vary depending on the pest and the species of the tree.
For instance, we spray for IPS and mountain pine beetles in the spring and summer. We do a first spray in March to target the first generation before they can attack the tree, and then we do another spray in the summer to protect against any larvae that might have been laid in the tree.
Meanwhile, we do bark injections every other year on ash trees to protect against the Emerald Ash Borer. These treatments are done in June, after the leaves have budded out.
Our insecticides are not safe for animals or children. We recommend keeping them inside while your trees are being sprayed, and not touching anything until it’s dry. Luckily, this shouldn’t take longer than 45 minutes, even less when it’s super hot out. Our sprays contain a strong bonding agent that, once the spray dries to the trees, will help the chemical last up to six weeks!
Soil injections may last up to 225 days, depending on the health of your trees and shrubs. Bark injections usually lasts 30 to 75 days.
