Why does my citrus tree keep turning yellow in Mesa?

Yellowing citrus in the East Valley is almost always iron chlorosis — Arizona's alkaline soil (pH 7.5–8.5) locks iron into an unavailable form. We inject chelated iron directly into the root zone to bypass the soil chemistry issue.

What is deep-root fertilizing?

We use a soil injection probe to deliver natural nutrients directly into the feeder root zone, 12–18 inches below the surface. This bypasses the compacted, alkaline surface soil and puts nutrition exactly where roots can absorb it.

Which trees benefit most from this service?

Citrus trees, mesquite, desert willow, palo verde, queens palm, and most ornamental trees in East Valley yards see significant improvement. Any tree showing yellowing, dieback, or slow growth is a candidate.

How is this different from just buying fertilizer at the store?

Surface-applied fertilizers in Arizona's alkaline soil rarely reach the feeder roots effectively. Our injected program gets natural nutrients past the caliche layer and directly to where the tree's active root tips are absorbing water and nutrients.

Feed your trees at the root — not the surface.

Deep-root injection of chelated iron, natural humates, and mycorrhizal inoculants — directly into the Arizona feeder root zone where it matters.

What Is Tree Fertilizing?

Arizona's alkaline soil locks away the iron, manganese, and micronutrients that trees need to survive the desert's extremes. Bug & Bloom's deep-root fertilizing program injects chelated minerals and natural humates directly into the feeder root zone — bypassing the surface soil layer that blocks nutrient uptake. Paired with mycorrhizal inoculants that build a self-sustaining root ecosystem, this is the difference between a tree that survives and one that thrives.
