After months of relentless triple-digit temperatures, many Phoenix trees show signs of stress—yellowing leaves, thinning canopies, or slowed growth. While our desert trees are tough, even the hardiest species struggle after a record-breaking summer. The good news? Fall is the best time to bring your trees back to health with professional care like deep root feeding and nutrient boosts.
Why Fall is Prime Time for Recovery 
1. Cooler Temperatures = Better Absorption
As heat eases, trees can retain more water, making nutrients more effective. This creates the perfect window for fertilization.
2. Soil Restoration
Heavy summer watering often leaves behind salt buildup, which limits root function. Fall treatments help flush salts and rebalance soil.
3. Root Growth Season
While leaves may slow down, roots are still growing actively in fall and winter. Feeding now strengthens them before the next summer.
3. Prevention for Next Year
Healthier trees going into winter sprout stronger in spring and withstand summer heat better.
How Deep Root Feeding Works 
Deep root feeding delivers slow-release fertilizer and vital supplements directly into the root zone, bypassing dry topsoil and ensuring maximum uptake. Our blend targets common deficiencies in Arizona soil:
Nitrogen for photosynthesis and energy production
Iron & Manganese to restore green foliage and prevent yellowing
Boron for healthy new growth and energy movement
Mycorrhizae (beneficial bacteria) to expand roots and boost water absorption
These treatments replenish what summer heat and irrigation have stripped away, giving trees the resources they need to repair and rebuild.
