While most areas in USDA zones 9b to 11 have enough nutrients in the soil to grow healthy avocado trees, a little extra boost from a high-quality, slow-release, organic fertilizer wouldn’t hurt.

NPK Analysis

NPK is short for nitrogen, phosphorus, and potassium.

These are the three main nutrients that plants need to grow healthy and strong.

Most fertilizers are identified by their ratio of these nutrients.

Avocado trees need a 2:1:1 ratio, which means they need twice the amount of nitrogen as they do phosphorus and potassium.

Works Best – This blend is common in fertilizers designed for citrus trees, so if you’re stumped looking at fertilizer, choosing a citrus-specific one is a good choice.

Nitrogen

Nitrogen is the nutrient that makes energy available to the avocado trees so they can produce healthier fruits.

Nitrogen by itself is more than sufficient as a fertilizer for avocado trees.

If you are just using nitrogen, the first year the avocado tree is planted it should be fertilized three times; once in the spring, once in the summer, and once in the fall.

Each of these fertilizer applications should be one tablespoon spread out around the base of the tree and then watered thoroughly.

Each year after that, the avocado tree should get 1/4 cup of nitrogen spread out between the same three application times.

Phosphorus

Phosphorus helps the avocado tree produce flowers and seeds.

When using a 2:1:1 blend, the phosphorus helps more flowers bloom, which will produce more fruits, and more seeds.

If you want a larger yield of avocados, phosphorus is important.

Potassium

Last but not least, potassium helps the avocado tree to absorb water and nutrients more efficiently.

It also strengthens the plant’s resistance to disease.

This increases the overall health of your tree, and although it doesn’t seem to affect the fruit or the yield, it does play a pretty significant role.

Without Potassium – The roots of the avocado tree won’t develop properly, and since the feeding roots are only about 6 inches deep, it could mean the death of your avocado tree.

What to Look For

When looking at fertilizers in-store or online, there are some things you should check the packaging for.

The best fertilizers will be made with 2:1:1 NPK so your avocado plant can produce strong roots that will support the tree while it produces fruits.

It should also contain high-quality, organic materials.

You wouldn’t want to feed your tree harmful pesticides or herbicides, especially if you want to eat the avocados your tree produces.

Good to Know – The fertilizer should also be a slow-release fertilizer. Plant spikes and granules will slowly release the fertilizer the avocado tree needs over a few months.

This is important to not overwhelm the roots, or even damage them with root burn.
