At Affordable Tree & Shrub Experts, we offer professional shrub and tree fertilization services designed specifically for Colorado’s challenging, nutrient-poor soils. With our semi-arid, desert-like climate, providing your vegetation with the nutrients they need is one of the most impactful steps you can take to promote long-term health and vitality.
Our team of experts uses only organic, pet-safe fertilizers that contain a complete blend of macro- and micronutrients, plus beneficial mycorrhizae—naturally occurring fungi that enhance root absorption. Unlike surface applications that often get washed away or miss the roots entirely, our treatments are injected directly into the soil with a liquid carrier, delivering nutrients right where your plants need them most.
Affordable Tree & Shrub Experts’ fertilization services ensure your landscape receives optimal care. Our liquid fertilizer system stimulates root growth, strengthens the plant’s natural defenses, and supports lush, vibrant foliage throughout the growing season. We also offer fertilizer spraying for targeted treatment of stressed or weakened trees.
Choosing the best fertilizer for shrubs and trees in our region requires local knowledge and expertise. That’s why our licensed arborists customize each fertilization plan based on your property’s unique soil composition and plant species. From evergreens to ornamental trees, we provide the specialized nutrients that support healthy, resilient growth.

Tree & Shrub Fertilization FAQs
What application method does Affordable Tree & Shrub Experts use?
We use sub-surface fertilizer injection into the ground with a liquid carrier solution. This is also known as deep root fertilization, a system in which nutrients are directly delivered into the root zone using a pressurized solution. Sub-surface injection improves nutrient uptake, relieves compacted soils, and supports overall tree and shrub health. This is the best method for Colorado soils, which often fall under desert or semi-desert categories.
How do I know if my trees or shrubs need fertilization?
Common signs include pale or yellowing leaves, small or stunted growth, early leaf drop, poor flowering, and thinning canopies. A site assessment can confirm whether nutrient deficiency or soil issues are present.
When is the best time to fertilize in Colorado?
The ideal windows fall in spring and autumn. This ensures that there is enough moisture in the soil and that the root network is active. Timing may vary based on species, soil conditions, and recent stressors like drought—our arborists can recommend the optimal schedule.
How often should I fertilize my trees and shrubs?
We recommend fertilization twice a year, or as needed for newly planted trees or those suffering growth. Our professional team can make tailored suggestions during the service.
Are your fertilizers safe for pets and children?
Yes, we only use organic, kid and pet-safe fertilizers.
