Tree Insect & Pest Control Programs
A wide range of insects is always present in the Colorado forest, including some that harm your trees and landscape. Pine bark beetles and the Ips beetle are just two, and create huge problems in our area (you can learn more on our page about controlling mountain pine beetle). We also have many other tree pests, like the Cooley Spruce gall, dwarf mistletoe and needle scale.
Two that are particularly prevalent in summer are -
Aphids - suck leaves dry and create black mold that sticks to leaves and whatever's beneath trees
Spider mites - Make small dots on leaves where they suck out sap, create webbing throughout the tree and you'll see dying leaves
Some, like the pine beetles, can kill your trees if not treated.
Treatment of Tree Diseases
Many of our local trees, especially aspens, are prone to disfiguring injuries (like deer or elk rubbing), as well as destructive diseases and pests such as those below -
Aspen leaf blight - aspen leaves fall off
Cytospora canker - aspen bark turns orange and the tree dies
However, with proper care, treatment and/or prevention - done at the correct time - the worst damage can often be avoided.
Tree injuries, diseases and insect pest problems need proper diagnosis and the right treatment to prevent damage and disfigurement to your trees.
Based on our analysis of the situation, we choose from a range of tree sprays and tree injections to quickly get the most effective treatment to the affected area(s).

Plant Health Care Programs
If you're looking to create a healthy and beautiful landscape, then Plant Health Care (PHC) is for you.
It goes beyond pruning, general maintenance and occasional fertilization and instead focuses on preventing issues from arising in the first place.
Why wait for something to go wrong with your landscape (like pests, diseases, storms and fire) when you can proactively manage it to avoid most of the undesirable outcomes.
While we can't prevent all problems, we CAN maintain and improve your landscape's health, appearance, vitality and safety.
