Tree Fertilizing and Deep Root Feeding for Healthier Trees in Phoenix
Desert soil is tough on trees. Much of the Phoenix area sits on alkaline, compacted, nutrient-poor ground with a layer of caliche underneath, and years of drip irrigation can leach out what little nutrition is there. The result is yellowing leaves, thin canopies, poor fruit and flower production, and trees that never quite look like they should. Fertilizing is not about dumping a bag of product at the base of the trunk. It is about giving each tree exactly what its soil is missing.
Heartwood Tree Care provides professional tree fertilizing and soil care for homes and properties across Phoenix, Scottsdale, Chandler, Gilbert, Mesa, Tempe, and the East Valley. Our ISA Certified Arborist assesses your trees and soil first, then applies the right products at the right time of year for lasting results. Call today to schedule a tree health assessment. On time, every time.

What We Do
Our fertilizing service is built around the specific needs of desert-adapted and non-native trees growing in Arizona conditions. Every program starts with an assessment, not a one-size-fits-all application.
- Tree health assessments. We inspect leaf color, canopy density, new growth, and root zone conditions to identify nutrient deficiencies such as iron chlorosis, nitrogen shortages, and micronutrient gaps common in alkaline soil.
- Soil evaluation. We look at drainage, compaction, salt buildup, and pH so we can correct the soil, not just feed the tree.
- The right products at the right time. We use professional-grade fertilizers, slow-release formulations, and soil amendments matched to the species and applied during the seasons when trees can actually absorb them.
- Deep root feeding. Where appropriate, we inject nutrients directly into the root zone below the surface, where trees take them up most efficiently and where they will not run off or feed the weeds.
- Proper care for water conservation and healthy growth. We pair fertilizing with watering recommendations so your trees use water efficiently and put their energy into strong, sustainable growth.
We serve citrus, fruit trees, flowering ornamentals, shade trees, palms, and native species like mesquite, palo verde, and ironwood.
Why it Matters
A tree that is struggling for nutrients is a tree that is vulnerable. Stressed trees are more susceptible to pests, disease, sunburn, and heat damage, all of which are constant pressures in the Valley. Proper feeding keeps the tree’s immune system strong and helps it survive the extremes of an Arizona summer.
Fertilizing also directly affects what you get out of your trees. Citrus and fruit trees that are properly fed produce more and better fruit. Flowering trees bloom fuller. Shade trees fill in their canopies and grow at a healthy rate, cooling your yard and your home. Under-fed trees do none of these things well, no matter how much you water them.
Finally, correct fertilizing saves money. Over-fertilizing wastes product, can burn roots, and pushes weak, fast growth that breaks in storms. Under-fertilizing leads to slow decline and eventual removal. A professional program that gives your trees what they actually need protects the long-term investment you have in your landscape.

Randy was good at explaining what he saw about the health of our trees and course of action. He also volunteered tips how to take care of some other trees on our property.
We had the bio-boost treatment to help a struggling ash tree and to also boost some orange trees that we planted last year. He was also a good natured and helpful person also volunteering some tips about care of our orange trees. The bio-boost is injected into the ground with a probe. Note: it may result in puncturing underground irrigation if unlucky. The probe poked a clean hole into our in-ground PVC irrigation lateral that I paid someone to come repair.
Another crew came to trim dead branches from our large tree and remove some stumps with a grinder. I thought they would just grind and leave holes. I was pleased that they cleaned up the debris, filled the holes, and covered with the surrounding gravel. Where there had been stumps, I could hardly tell there had been anything there before at all. Will was the crew's lead person who spoke with me during their time in our yard. I also found him to be good at explaining and I felt like he actually did care about the quality of work being done. I hope that Heartwood will reward him and the others who came with him.
