It’s packed with nutrients and minerals that avocado trees need to flourish, including all-natural ingredients such as earthworm castings, fish meal, crab meal, and bat guano.
One of the most important components of the best soil for avocado trees is that it must be well-draining. Few things will kill your trees faster than when the roots hold onto moisture and start to rot. As such, soils mostly composed of sand, loam, limestone, and granite bits are usually the best soil for avocado trees.
Ocean Forest fits the bill, as it’s mostly sandy loam soil that drains well.

The combination of a solid root structure and excellent drainage makes Ocean Forest potting soil the best soil for avocado trees.

Miracle-Gro Moisture Control Potting Soil
There are few brands as readily recognizable as Miracle-Gro when it comes to potting soils and fertilizers.

It only seems fitting that a name with as much history and success takes the runner-up spot on our list of the best soil for avocado trees.
Moisture Control potting soil from Miracle-Gro is great for avocado trees because of its composition. Rather than the traditional sandy loam soil most avocado tree soils use, Moisture Control consists of peat moss, coconut coir, perlite, and other forest products. It has that much sought-after combination of top-notch drainage and moisture retention when it’s needed.
Because soils of this type often don’t have enough natural nutrients inside of them, Miracle-Gro adds their signature blend of fertilizer. This also happens to be the most budget-friendly potting soil on our list, so it’s great for beginners who are getting their feet wet before diving into the deep end. The only downside of Miracle-Gro products is that they use synthetic materials and are chemically formulated.

Using organic soil is also considered the purest way to grow avocado trees.

Best Soil for Dry Areas
Fertilome Cactus Potting Soil
If you live in dry, arid areas of the world where your avocado tree isn’t going to get as much water as it should, you’ll have to use a different kind of soil. Rather than one that drains excessively quickly, the best soil for avocado trees in dry areas should be soil that retains moisture. For this reason, using cactus soil, such as Fertilome Cactus Potting Soil, is an excellent option.
Fertilome cactus soil is coarse to the touch and consists mainly of perlite, crushed-up granite, and sand. Because of these ingredients, Fertilome drains quickly enough that root rot and other moisture-related diseases won’t set in, but not so soon that your avocado tree won’t get the water it needs to survive.
The downside of using cactus soil for avocado trees is that it typically doesn’t contain a ton of nutrients or fertilizers. As such, it will be up to you to supplement this lack of fertilizer with other products such as Fox Farm Happy Frog Citrus and Avocado Dry Fertilizer. As long as you add this fertilizer as recommended to your Fertilome Cactus Potting Soil, your avocado tree will grow tall and fruitful.
- The ability to drain quickly but hold on to moisture dry areas
- Provides ample root stability
- Tailor-made for slowly growing your avocado tree
- It doesn’t contain nutrients which means you’ll have to add your own

What to Look for When Choosing the Best Soil for Avocado Trees
There are several things to consider when choosing the best soil for avocado trees, and here are a few of the main things to look for when making your selection.
Type of Soil
Like we said before, the type of soil you choose will largely determine the success of your avocado tree. Because there are many different types of soil, this is sometimes easier said than done. When it comes to avocado trees, a combination of quick drainage, moisture retention, and root stability is what to look for.
Sand, loam, peat moss, coconut coir, forest humus, bark, perlite, limestone, and crushed granite are the main soil ingredients to look for. These products ensure each of the qualities necessary for avocado trees to grow tall and produce abundant fruit.
Most of the soils we looked at on this list, except for Fertilome Cactus Soil, have added nutrients and fertilizers. Organic soils will contain natural nutrients such as earthworm castings, fish byproducts, bat guano, and compost, while non-organic soils will have synthetically-produced fertilizer. Both types of soil will provide your avocado tree with the nutrition it needs, but organic soils are purer and less damaging to the earth around it.
If you’re only going to take one thing away from this article, it should be that avocado trees MUST have good drainage. Root rot and other moisture-related diseases are extremely dangerous to them, and the best soil for avocado trees will have quick, uninhibited drainage.
pH level refers to the level of acidity of the soil in which your avocado tree is planted. For best results and maximum growth, you should choose soil with a pH level between 6.0 and 7.0, with 6.5 being perfect. If necessary, you can tweak the soil’s acidity by adding a pH neutralizer or enhancer to reach your desired levels.
You probably didn’t realize that certain types of soil contain trace amounts of salt. As you water your avocado tree, the salt can harden and form crystals that are detrimental to your tree’s health. To be the best soil for avocado trees, it shouldn’t contain salt in any form.
Get Off to a Great Start With the Best Soil for Avocado Trees
If you’re worried that you won’t be able to choose the best soil for avocado trees on your own, there’s no need to worry. By choosing one of the options on this list, you all but guarantee a healthy and prosperous avocado tree. As long as you follow the instructions on your potting soil and learn how to care for your avocado tree like a pro, you’ll be able to enjoy fresh avocados for years to come!
