Using the right type of soil for plumerias is key to their overall good health, whether they are in containers or the ground.
Using the wrong soil can cause problems, and even harm or kill your frangipani, so it’s crucial to get it right.
In this post I’m going to tell you everything you need to know about choosing the perfect plumeria soil, and I’ll share my recipe and guidelines for making your own mix.
Read on to discover the perfect type to use, the properties it should have, and how to easily mix your own with my simple recipe.
What Kind Of Soil Do Plumerias Need?
When choosing the correct type of soil for your frangipani plant, it’s important to remember that they store excess water in their stems and branches.
This means they don’t like to be planted in a medium that retains moisture, and instead prefer a quick-draining soil.
Using the right kind will avoid common problems, such as lack of flowers, poor growth, overwatering, and root rot.
Plumerias also like their soil to be slightly acidic, as this makes it easier for them to absorb the nutrients they need.

The Best Soil For Plumeria Plants
The best soil for plumeria plants and trees is a sandy, slightly acidic medium that drains quickly.
A sandy commercial mix would be ideal, or you could make your own using my recipe below.

Read the label and select a medium that lists fast drainage as its main quality.
Avoid heavy garden mixes, topsoil, or any medium that’s described as ‘moisture retentive’.
A porous medium will be loose and aerated, allowing water to drain through it quickly without retaining too much.
This is another good indication that the mixture will be ideal for your plumeria plant.
Check the nutrient content of the mix to find one that contains rich organic materials, rather than chemical fertilizers.
These will provide your frangipanis with the natural nutrients they need to thrive, without the risk of burning the roots.
Plumeria Soil pH
Plumerias prefer a slightly acidic soil ranging between 6-7 on a pH meter probe.

Using a commercial potting mix is convenient, but it’s actually very quick and easy to make your own.
Not only is this often cheaper, but it also gives you complete control over the ingredients and consistency.
Plumeria Soil Recipe
Below is my recipe for DIY plumeria soil. You can either make a small batch to use right away, or mix more and store the leftovers for another time.
I use a 1-gallon bucket to measure my parts, but you could use a scoop, measuring cup, or even a large spoon if you prefer.
Just be sure to use the same measuring container throughout for consistency.
- 1 part peat moss
- 1 part coco coir
- 1 part perlite or pumice
- 1 part coarse sand
- 1/4 part ¼” pine bark (optional)
- Peat moss or coco coir – These can be used interchangeably and help improve water retention, aeration, and drainage.
- Perlite or pumice – These can be substituted for each other. They help aerate the soil and stop it from retaining too much moisture.
- Coarse sand – Sand helps create tiny air pockets in the soil, allowing water to drain freely and making it easier for roots to grow. Suitable substitutes include turface and poultry grit.
- Pine bark – Although it’s not essential, this enriches the soil with organic matter as it breaks down, improving its structure and helping it retain nutrients. You could use orchid bark or coco coir chips instead.

Your homemade plumeria potting soil is ready to use right away, but if you’ve made a big batch you’ll probably want to store some for later.
Store the bucket in a cool, dry location, and be sure to label it clearly – homemade soils can look very similar once mixed.
