Why is My Avocado Tree Not Growing? The Answer

Sharing is caring!

Growing an avocado tree can be both a rewarding and challenging experience, often leaving you questioning if you’re doing it right, especially when progress seems slow.

While it may simply be a matter of time before your tree thrives, other underlying reasons could be affecting its growth.

Let us now have a closer look at these potential problems.

Why is My Avocado Tree Not Growing?

Your avocado tree is not growing because it may be affected by root rot or black streak, both fungal infections that hinder growth. Incorrect depth of the root ball, inadequate nutrients, and poor growing conditions can also impede its development.

Your Avocado Tree is Suffering from Root Rot

Avocado root rot is a common fungal infection resulting in annual large crop losses. The fungus targets the tree at the roots and causes the roots to become brittle and blackened.

This prevents the tree from being able to absorb nutrients from the soil, thus inhibiting the growth of the tree.

Since most of the infection occurs underground, you probably won’t notice anything wrong with your tree. Signs of root rot include small, yellow, or lighter green leaves that become wilted over the progression of the disease.

Fortunately, root rot is preventable simply by planting avocado trees in an area with adequate drainage or choosing to plant cultivars that are resistant to root rot.

Fungicides and certain fertilizers can also assist in combating root rot.

How Black Streak Disease Affects Your Avocado Tree

Avocado black streak is another disease that can prevent the growth of avocado trees and even cause them to die eventually.

Although its exact cause isn’t known, it is suspected to be the result of another type of fungal infection.

Just as overwatering contributes to the development of root rot, black streak is associated with avocado trees that have experienced drought.

Avocado black streak can be prevented with sufficient irrigation and proper fertilization of avocado trees.

Although Black Streak can affect young avocado plants and inhibit their growth, it can also impact older trees.

Signs of Black Streak include discolored bark and the development of cankers on the tree’s limbs.

The Impact of Deep Planting on Avocado Tree Growth

If your avocado tree is sprouting healthy, green leaves but failing to grow any further, you may have simply planted it a little too deeply into the ground.

Ideally, the initial horizontal root growing from the stem of the tree should be right at the surface of the soil or one inch above it.

With small adjustments to the planting of your avocado tree, you should be able to easily resolve this issue and expect your tree to continue to grow healthily.

Nutrient Deficiencies Stunting Your Avocado Tree

If an avocado tree is not receiving the proper amount of nutrients, its growth may become stunted and it may fail to produce fruit.

Although soil is sufficient for some plants, avocado trees need nutrient-rich fertilizer that supplements any deficiencies in the soil for them to be able to thrive.

Specialized fertilizer isn’t required for avocado trees, but they do need an adequate amount of nitrogen and zinc to ensure proper growth.

Avocado trees should be fertilized three times throughout the year after they are planted, but you can reduce the need for fertilization by properly planting your avocado trees in aerated soil during warmer weather.

Environmental Factors Affecting Your Avocado Tree’s Health

Avocado trees need to be planted in a well-drained area with direct sunlight, ideally away from other plants that may also be competing for nitrogen in the soil.

If they are planted in a spot that is prone to flooding, this increases their susceptibility to root rot.

Avocado trees can be negatively affected by wind and frost, so you want to plant them in an area protected from harsh elements.

Often, an avocado tree is failing to grow and thrive because it was planted in an unsustainable environment, or it’s receiving too much or too little watering.

Frequently Asked Questions About Why Avocado Tree Is Not Growing

What is the Best Place to Plant an Avocado Tree?

Avocado trees thrive best when they are planted in soil that is well-drained and in an area that will expose them to adequate sunlight. Although you want to avoid planting an avocado tree anywhere that is flood-prone, valleys do offer the trees a source of protection from the wind.

Do You Need to Plant Two Avocado Trees in Order to Obtain Fruit?

Avocado trees do need to pollinate in order to produce fruit, but they are capable of self-pollination. While it is possible for fruit to develop when only one tree has been planted, the planting of two trees increases the likelihood of pollination occurring and avocados yielding from the trees.

What’s The Best Fertilizer You Can Use For Avocado Trees?

Standard fertilizers are fine for avocado trees provided they contain nitrogen and zinc. You can also purchase citrus or avocado tree fertilizers or create your own homemade fertilizer using compost or coffee grounds.


If your avocado tree isn’t growing, you may simply need to give it a little more time.

Otherwise, altering the depth of the planting, providing the tree with adequate nutrients, or adjusting the watering regimen may do the trick.

When planting avocado trees, you need to be aware of potential fungal infections and be selective about where you plant the tree.

With a few minor adjustments in planting and caring for your tree, it will start to thrive, and soon, you’ll enjoy plump, delicious avocados.
