Best Soil for Avocado Trees in Dry Areas

Fertilome Cactus Potting Soil

Fertilome Cactus and Succulents Mix 4 Quart Bag

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.

Pros

  • The ability to drain quickly but hold on to moisture dry areas
  • Provides ample root stability
  • Tailor-made for slowly growing your avocado tree

Cons

  • 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.

Nutrients

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.

Drainage

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

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.

Salt Level

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.
