Comprehensive Tree and Shrub Fertilization Services
Colorado’s landscape often has poor soil quality that lacks the nutrients your trees and shrubs need to thrive. Proper fertilization strengthens their roots, improves growth, and boosts overall plant health, preventing common issues caused by poor soil nutrition. Well-nourished plants are more resilient to environmental stresses, have better resistance to pests and diseases, and exhibit more vibrant foliage and robust growth. Our fertilization services ensure your trees and shrubs have the essential nutrients to flourish, enhancing your landscape’s overall beauty, longevity, and vitality.
Signs Your Trees and Shrubs Need Fertilization:
- Loss of foliage
- Slow growth and weak crowns
- Poor color development
- Increased insect infestations
- Higher susceptibility to diseases and freeze damage
- Spindly growth patterns with thin branches
- Reduced flowering and fruit production

Troy and his crew did a TON of work at our place this Spring and finished it in one day. A couple of our trees that were struggling and had a lot of dead-looking branches were treated with extra care. The crew cleaned up the yard nicely, even using a blower to get the dust off the patio. Great work!

I used American Tree to prune and clean up an ash tree that had been really neglected. They trimmed it up to look fantastic. Cleared out all the dead and gave it a great canopy again. Cleaned up everything and were very professional. Will use them again.
