Key features

Top-rated avocado fertilizer in a complete, pre-measured kit.
Controlled-release NPK 18-6-12: slow-release nutrients for months of feeding.
Micronutrients (iron, manganese, zinc, copper, and molybdenum) to fight yellowing.
Calcium, magnesium, and boron: stronger roots and better fruit.
Sized for container and patio avocado trees in a 3-gallon pot or smaller.

Ingredients

  • Controlled-release NPK fertilizer (18-6-12): poly-coated, long-lasting nutrition tailored to avocados.
  • Micronutrient blend: iron, manganese, zinc, copper, and molybdenum to prevent deficiency.
  • Calcium nutrient concentrate: calcium, magnesium, and boron for fruit quality and root health.

How to use

  1. Fertilize the soil: sprinkle the controlled-release fertilizer evenly around the base of the tree on the soil, not touching the trunk. Do not mix it with water. Reapply every 2 months.
  2. Feed the leaves: spray the trace element solution on the leaves until run-off, or apply as a soil drench, every 4 to 6 weeks during active growth and any time to correct yellowing.
  3. Support fruit: spray the calcium solution on the leaves, or apply as a soil drench, before and at bloom and as fruit sets.

Why?

Why choose a full avocado fertilizer kit instead of just a bag? Avocado trees need more than just nitrogen, they need complete nutrition. This kit delivers a precise NPK formula with micronutrients and calcium to support green, lush growth, strong roots, and good fruit, all pre-measured so you feed correctly without over-fertilizing a salt-sensitive tree.

Makes how much?

Each kit feeds one container or patio avocado tree in a 3-gallon pot or smaller for a full season, with minimal reapplication. Feeding a large avocado or a tree in the ground? The Large & In-Ground Avocado Kit covers a 30-gallon tree, two 15-gallon trees, or three 10-gallon trees.

Frequently Asked Questions

Which avocado trees is this for?

Container and patio avocado trees, including dwarf varieties, in a 3-gallon pot or smaller, grown outdoors, on a balcony, or indoors in bright light.

How often should I feed my potted avocado?

The controlled-release granule feeds for months, so it goes down a few times a season, while the trace and calcium sprays are applied every four to six weeks per the included schedule.

Why are my avocado leaves yellowing or their tips turning brown?

Yellowing usually means nitrogen or iron is running low, and avocados are heavy nitrogen feeders. Browning leaf tips are different and often mean salt buildup from over-fertilizing or hard water, since avocados are salt-sensitive. This kit's controlled-release feed is gentler, and watering deeply now and then helps flush salts.

Can I use this on an indoor avocado?

Yes. It suits patio, balcony, and indoor container avocados in bright light, applied on the same simple schedule.

Is it safe for edible fruit?

Yes, when applied as directed on the label.

How is this different from the large kit?

This kit is sized for one avocado in a 3-gallon pot or under. If you are feeding a large container tree or a tree in the ground, the Large & In-Ground Avocado Kit is built for that, covering a 30-gallon tree, two 15s, or three 10s.

All about feeding container avocado trees

Why container avocados need their own approach

A potted avocado depends on a small volume of soil, so nutrients wash out faster than the tree's size suggests. Avocado roots are also salt-sensitive, which is why this kit uses a controlled-release feed instead of a heavy, fast-release dose.

Avocados are heavy nitrogen feeders

Avocados lean hardest on nitrogen for leaves and growth, which is why this kit's 18-6-12 blend is nitrogen-forward. The included trace spray covers the zinc and iron avocados commonly run short on.

Why avocado leaf tips brown, and how to avoid it

Browning leaf tips usually mean a salt buildup from over-fertilizing, not hunger, since avocado roots are salt-sensitive. This kit's controlled-release formula feeds gently to help avoid that, and watering deeply now and then flushes out excess salts.

Pro tips for container avocado care

Use a well-draining potting mix, since avocados hate wet, heavy soil.

Do not over-fertilize, because avocados are salt-sensitive and heavy feeding backfires.

Water deeply now and then to flush salts, and let the top inch of soil dry between waterings.

Give the tree bright light, and watch for small or pale leaves as a sign to lean on the trace spray.

How the three-in-one system works

Avocados need more than nitrogen, phosphorus, and potassium, which is why this kit pairs the granular feed with two sprays. The controlled-release 18-6-12 granule handles the base nutrition at the roots and feeds gently for months. The trace element spray delivers the iron, manganese, zinc, copper, and molybdenum avocados run short on. And the calcium, magnesium, and boron concentrate supports fruit quality and root health, all sized and metered so a salt-sensitive tree is fed well without spikes.

Container or in-ground: which kit do you need?

This kit is sized for one avocado in a 3-gallon pot or smaller. If your tree has moved into a large container or gone into the ground, the Large & In-Ground Avocado Kit is built for that and covers a 30-gallon tree, two 15s, or three 10s.
