Bliss Gardens Organic Succulent and Cactus Soil
This hand-made potting soil mix is designed for fast drainage while still containing ingredients that can hold moisture and make it available to your plants.

But it’s the addition of coco coir, peat moss, and horticultural charcoal that makes it quite different from the options above and give it its ability to provide more moisture.
Coco coir is made from the fibers on the outside of coconut husks. And it’s used in potting soil for its ability to absorb water but also let excess easily drain from the mix.
The porosity of the horticultural charcoal allows for further absorption and retention of water and fertilizer. Making it slowly available to your plants over time and increasing the nutritional holding capacity of the mix.
Also included is bat guano, and worm castings. Providing a small amount of nutrients for plant growth.
And mycorrhizal fungi that help to increase the uptake of nutrients by your succulent’s roots. Leading to stronger and healthier growth.

To get your plants growing it contains a small amount of fertilizer. But you’ll have to start adding it yourself after a few weeks.
And this does lead to a drawback, as some people dislike the natural fertilizer smell.
Some people also complain that it holds water too easily due to the amount of peat moss it contains.

The texture of the soil is nice and fluffy, and most customers report good drainage and successful results. It’s excellent for starting seeds and propagating succulents from leaves and cuttings.
However, it does contain a lot of peat moss and peat. And as a general rule of thumb, most succulents do best in soil consisting of larger, grittier particles, and less organic matter.

Choosing The Best Succulent Soil
One of the most important tips for successfully growing succulents is getting the right soil.
The best soil for succulents should be able to provide the following 4 things for your plants:
- Nutrients to help your plant grow – plants need the primary nutrients nitrogen (N), phosphorus (P), and potassium (K) in the greatest quantities. They also require a smaller amount of the secondary nutrients calcium, sulfur, and magnesium. And trace amounts of a number of other elements.
- Anchorage for the roots – without a solid enough structure for the roots to grip into your succulents will have stability issues.
- Access to water – different materials in soils have a different ability to retain moisture.
- Aeration – there needs to be enough space between soil particles for plant roots to access oxygen.
What makes A Good Soil For Succulents?
Firstly, don’t be tempted to use the topsoil from your garden. It’s a poor choice for succulent plants grown in containers because it’s too heavy. It compacts easily, retaining too much water, and preventing access to oxygen.
And the big thing about growing succulents is that they need soil that drains really well.
You see, wild succulents come from arid regions and grow best in gritty soils. The sort that dry out rapidly after rainfall. And succulents have evolved to be resistant to drought-like conditions.
But this also means they are susceptible to root rot if they’re left in soil that retains water too easily.
So you need to try and mimic the natural conditions they like as close as you can.
There are a number of factors that affect the length of time that soil stays wet:
- Exposure to sunlight
- Amount of airflow
- Volume of water absorbed
- The structure of the soil
When buying a soil to use, and when making your own adjustments to create the ideal conditions, remember that the time it takes for soil to dry is a balance of these 4 things.
So, what works well for one gardener in a specific location, might not work as well for someone else in slightly different conditions.
For example, if you’re growing your succulents outside where it’s hot and windy then the soil may dry out very quickly. Using a less porous soil mix might be preferable so you don’t have to water them too frequently.
Whereas if you’re growing inside with limited airflow you might prefer a more sandy and gritty mix that’s faster draining.
Don’t forget when growing your succulents in containers or a succulent planter to make sure they have good drainage holes in the bottom for the water to escape from. It won’t matter if you have the best succulent potting mix if the water can’t exit the container efficiently.
For this reason, we don’t really recommend making a succulent terrarium. The drainage problems after watering make it hard for the plants to thrive.
Getting The Right Soil Composition
To look at it in a simple way, your soil is made up of 2 types of ingredients: organic and inorganic.
The organic part of the soil consists of things that were once living but are now dead. Sometimes, they are in a state of decomposition as bacteria begin to break them down, eventually releasing the nutrients they contain into the soil.
The inorganic part consists of minerals, such as sand, gravel, bits of rock, etc
In order to create good succulent soil recipe the ratio of organic to inorganic materials is important.
The organic part of the soil will hold and absorb water. Whereas the greater the amount of minerals in the soil the better it will drain. Finding the perfect balance will enable fast-drainage, preventing root rot. While still holding enough moisture for healthy growth.
For growing succulents, the quantity of minerals in the mix can range between 40-80%. Depending on the type of succulent and the conditions you’re growing in.
Whether you’re buying a ready-made mix or looking to make your own DIY succulent soil, these are some of the ingredients to look out for:
Some commercial potting soils don’t use organic materials at all, because they can hold too much water. But these are often used:
Sphagnum Peat Moss
This is a common ingredient used to build potting soils and give them structure and aeration.
But it also holds water. And while that’s good for many types of plants, it can be a problem for succulents if it’s used in too great a quantity in the mix.
It’s also hydrophobic when dry, and needs to be slowly soaked to become fully saturated. Making it difficult to quickly drench succulent roots.
It’s acidic, which is a good thing, as most succulents like growing in a slightly acidic pH around 5.5-6.
This consists of the fibers found on the outside of coconut husks. It absorbs water well, but is better than peat moss at allowing excess water to quickly drain from the soil so many people prefer it.
There are many different types of minerals you can use to make the best potting mix for succulents. Good choices for well-draining soil include coarse sand, pumice, and perlite.
If you come across them, it’s best to avoid non-calcined clays and vermiculite. These are sometimes used in potting soil, but they are too water-retentive for ideal use.
Sand is simple and effective for increasing drainage. But it’s important that you use coarse grain sand and not play sand or beach sand.
This is a lightweight volcanic glass that’s very common to find in good potting soil. Mixes containing part perlite have improved drainage and aeration because it can prevent soil from compacting.
Pumice is a volcanic rock that provides many of the same properties to potting soil as perlite. But it’s a bit heavier, and less likely to spill over the edge of the pot when you water, or blow away in windy conditions.
Formed by heating clay to a high temperature, calcined clay is very good at absorbing water while preventing saturation of the soil mix by letting the excess drain. It then slowly releases the water to your plants as needed.
Getting the right soil for your succulent garden is the most important thing you can do to help them grow and thrive. Because they’re used to dry conditions, soils that retain too much water will lead to rot. So you need a soil mix with excellent drainage.
