Tree Care Questions

When is the best time to trim trees in Colorado?

Late fall through early spring is generally ideal for most tree species, as trees are dormant and trimming causes less stress. However, timing can vary by species and specific circumstances. Our arborists can recommend the optimal timing for your particular trees.

How do I know if a tree needs to be removed?

Signs include significant structural damage, extensive disease or pest infestation, dead or dying sections, dangerous lean, root damage, or proximity to structures or power lines. Our certified arborists can perform a thorough hazard evaluation to assess whether removal is necessary.

What's the difference between tree trimming and pruning?

The terms are often used interchangeably, but pruning typically refers to selective removal of branches to improve tree health, structure, and appearance, while trimming may include general shaping and size reduction. We follow ANSI A300 standards for all pruning work.

Can you save a tree infested with mountain pine beetles?

If caught very early, some trees can be treated with preventative insecticides. However, once beetles have established and the tree shows extensive damage, removal is usually the best option to prevent spread to nearby trees.

Plant Health Care Questions

What is iron chlorosis and how do you treat it?

Iron chlorosis is a nutrient deficiency common in Colorado's alkaline soils that causes yellowing leaves. We treat it with specialized trunk injections or soil treatments that deliver iron directly to the tree's system, providing rapid and long-lasting results.

Do trees need water in winter?

Yes! Winter drought is a serious problem in Colorado. Trees need supplemental water during dry winter months, especially before the ground freezes. Our deep root watering service ensures moisture reaches the critical root zone.

How often should I have my trees treated for pests and diseases?

It depends on the specific issues and tree species. Many clients benefit from annual or semi-annual plant health care programs that include regular monitoring, preventative treatments, and fertilization customized to their landscape's needs.

What's included in a plant health care program?

Our comprehensive programs typically include regular inspections, pest and disease monitoring, nutrient management, soil amendments, preventative treatments, and ongoing consultation with our certified arborists. Programs are customized to your property's specific needs.

Wildfire Mitigation Questions

What is defensible space?

Defensible space is the area around your home where vegetation has been modified to reduce wildfire risk. It typically consists of multiple zones with varying levels of vegetation management, creating a buffer that can slow or stop the spread of fire.

Do I need to remove all trees near my home?

No. Strategic thinning and proper spacing of healthy trees, combined with removal of dead material and ladder fuels, is usually sufficient. The goal is to reduce fire intensity and spread, not eliminate all vegetation.

Are there grants or assistance programs for wildfire mitigation?

Yes, several Colorado counties offer cost-share programs for wildfire mitigation work. We can help you understand what programs may be available in your area and assist with the application process.

How often should defensible space be maintained?

Defensible space requires ongoing maintenance. Annual assessments are recommended, with work typically needed every 2-3 years depending on vegetation growth rates, tree health, and changing conditions on your property.
