Preparing Citrus Trees for a Sweet Harvest

Post on August 15, 2025

Citrus trees are one of Arizona’s greatest gardening treasures, offering fresh, juicy fruit straight from your own backyard. Whether you have oranges, lemons, grapefruits, or limes, late summer and early fall is the perfect time to give them a nutrient boost so they produce bigger, sweeter, and healthier fruit.

With Super Feed by Vital Gro, you can provide your citrus trees with the balanced nutrition they need to thrive in Arizona’s unique climate.

Why Fertilizing Now Matters for Citrus Trees in Arizona

In our desert climate, citrus trees work extra hard during the summer to stay hydrated and healthy. By late August and September, they’ve used up much of their stored nutrients. Fertilizing now:

Supports fruit development for sweeter, juicier harvests
Strengthens trees so they resist pests and diseases
Encourages healthy leaf growth to protect fruit from sun damage
Replenishes nutrients lost during the intense summer heat

🌿 Pro Tip: Pair your feeding with a deep watering schedule — you can read our Arizona Tree Watering Guide for the best results.

The Nutrients Citrus Trees Need for a Great Harvest

Citrus trees in Arizona benefit most from a fertilizer rich in:

Nitrogen (N): Promotes strong, healthy leaf growth for photosynthesis.
Phosphorus (P): Encourages robust root and flower development.
Potassium (K): Improves fruit size, flavor, and overall quality.
Micronutrients: Zinc, iron, and manganese are essential for preventing yellow leaves and maximizing fruit sweetness.

Super Feed by Vital Gro delivers these nutrients in a slow-release form, ensuring your citrus trees get consistent nourishment without the risk of burning.
