Product description

The Best Fertilizer Kit for Large Avocado Trees: Pre-Measured & Ready to Use

If you’re growing a mature or in-ground avocado tree, you’ve just found the perfect nutrition solution.

Our Large Tree Avocado Fertilizer Care Kit delivers the precise nitrogen, phosphorus, and potassium balance scaled for big trees. With controlled-release NPK fertilizer plus a powerful micronutrient and calcium package, it fuels vigorous canopy growth, stronger roots, and premium fruit production—season after season.

  • No mixing guesswork
  • No juggling multiple products
  • Just bigger, healthier harvests

Designed for trees 6 ft+ tall, in 15-gallon+ containers, or planted in-ground, this kit supports deep root systems and heavy fruit loads.

Key features

Complete avocado fertilizer system sized for larger trees
Controlled-release nutrition feeds for 4–6 months
Micronutrients (iron, zinc, manganese) to prevent yellowing and keep foliage dark green
Extra calcium for stronger roots, thicker fruit skins, and longer shelf life
Perfect for mature container trees or in-ground plantings

Why?

A big tree’s nutrient demand is higher and more complex than nitrogen alone. This kit delivers balanced NPK plus targeted micros and calcium, so you never have to guess or over-fertilize. It’s the smart, all-in-one way to feed a mature avocado tree.

Makes how much?

One kit nourishes one large avocado tree (in-ground or 15-gallon+ container) for an entire growing cycle—about 4–6 months depending on climate.

Understanding NPK for Large Avocado Trees

Why bigger trees need bigger balance
In-ground and large-container avocados draw nutrients from a wider soil volume but burn through them faster during heavy flowering and fruiting. Correct NPK ratios support lush foliage (N), strong roots and blooms (P), and firm, flavorful fruit (K).

  • Spring flush: Higher nitrogen for leaf and shoot growth
  • Summer fruiting: Increased phosphorus and potassium
  • Fall prep: Balanced NPK to strengthen wood and buds for winter

Signs of imbalance

  • Nitrogen shortage: pale, stunted leaves
  • Phosphorus shortage: poor root growth, purple leaf tint
  • Potassium shortage: brown edges, small fruit

This kit’s research-based NPK ratio and controlled-release coating keep nutrients available when the tree needs them most.
