Everything You Need to Know About Fertilizing Mature Citrus Trees

The Challenges of Fertilizing Large Citrus Trees

Large citrus trees—whether in 45-gallon containers or planted in the ground—require more precise care to meet their higher nutrient demands. Their larger canopy, extensive root systems, and fruit production cycles need sustained nutrition to avoid nutrient deficiencies.

Why This Fertilizer Kit is Perfect for Mature Citrus Trees

This kit is specifically designed for mature citrus trees, combining slow-release NPK fertilizer with trace nutrients and a calcium spray. The unique formulation provides a steady nutrient supply to promote strong roots, vibrant foliage, and optimal fruit production.

Pro Tips for Large Citrus Tree Care

  • Fertilize at the Dripline: Always apply fertilizer at the tree’s dripline (where the canopy ends) to ensure nutrients reach the active root zone.
  • Prune Strategically: Remove dead or damaged branches to direct energy to healthy growth and fruit production.
  • Seasonal Feeding Schedule: Feed large citrus trees seasonally, ensuring they have enough nutrients during flowering and fruiting stages.

How This Kit Enhances Citrus Growth

This fertilizer kit supports large citrus trees through every stage of growth. The slow-release granules nourish the tree over six months, while the calcium spray prevents fruit defects like splitting or blossom-end rot. It’s the ideal solution for both professional growers and backyard gardeners who want a bountiful harvest.

Understanding In-Ground vs. Container Citrus Care

Mature citrus trees in the ground benefit from deep root systems, but they can still suffer from nutrient deficiencies if the soil is poor. Container citrus trees, on the other hand, require more frequent feeding because nutrients leach out faster. This kit provides tailored nutrition for both types of trees, ensuring they thrive in any setting.
