Using the right kind of soil for your spider plant is important to keep it happy and healthy. While they’re not too fussy, they do prefer a nutrient-rich mix that drains well.
In this post, I’m going to explain all you need to know about spider plant soil. I’ll also share my simple recipe and step-by-step instructions for making your own mix.
Plus you’ll learn how to choose the best type to use, the properties that make it suitable, and how to properly store the leftovers for later.
The Best Soil For Spider Plants
The best soil for spider plants is a loamy, nutrient-rich, lightweight, quick-draining medium that provides good aeration and has a neutral to mildly acidic pH level.
I recommend buying a high-quality general purpose potting mix, or using my simple recipe below to make your own.
How To Choose The Right Soil
To make sure that the soil you choose is perfect for your spider plant (also known as Chlorophytum comosum, or airplane plants), check the packaging for the following properties:
- Well-draining – The label should say something like “fast draining” or “well draining”. This will allow excess water to flow readily from the pot, and prevent the medium from becoming overly wet or soggy.
- Loamy and nutrient-rich – To keep your plant healthy and vibrant, look for rich, fertile soil. Avoid mixes that contain chemical fertilizers, and look for one made from natural or organic ingredients instead.

- Moisture retentive – Although your Chlorophytum comosum won’t do well in very wet soil, it doesn’t like to be completely dry out either. Choose a mix containing ingredients that naturally retain moisture, such as peat moss and pine bark.
- Porous mix – Spider plants love porous soil because it is loose and aerated. This means that water will pass through it easily, preventing it from retaining too much, and keeping the moisture level just right.
- Mildly acidic – Airplane plants prefer neutral to mildly acidic mix ranging between 6.1 – 7.5 on a probe meter. If it is too alkaline the tips of the leaves may turn brown and begin to die back. You can add acidic fertilizer granules if it’s too alkaline, or garden lime to neutralize it.

Making DIY Spider Plant Soil Mix
You could use a general purpose potting medium for your spider plant, or try making your own. It’s easy to do and gives you full control over the ingredients. Below is my recipe and tips for mixing it.
You only need 4 ingredients to make your own homemade spider plant soil mix using my recipe. Below I’ll tell you the purpose of each one, and give you substitutions incase you can’t find them.
- Peat moss – Improves water retention, aeration, and drainage while also providing nutrients. You can use coco coir instead, if you prefer. In that case, add some acidic granules.
- Pine bark – Provides additional nutrients as it breaks down, prevents compaction, and helps to improve drainage.
- Coarse sand – Helps to ensure that the mix drains quickly. You can substitute turface or poultry grit. Some people like to use crushed granite or aquarium rock instead.
- Perlite – Adds drainage and aeration and also prevents compaction. If you can’t find it where you live, then you can use pumice instead, which is very similar.
Tips For Mixing Your Homemade Spider Plant Soil
Moisten the peat moss if it’s dry, then pour all of the ingredients into a table-top potting tray or bucket.
Stir everything together with a hand trowel or shovel. Make sure all of the ingredients are thoroughly mixed together before using.
Storing The Leftovers
You can use your DIY spider plant potting soil right away or store the leftovers for later. To keep it safe, use a 5-gallon bucket with a tight-fitting lid. This creates an airtight environment that will protect it from bugs and pathogens.
Store the bucket in a cool, dry location and label it clearly, as it can be very difficult to tell homemade mediums apart once they’re mixed.
While you could use cactus mix for your spider plant, I don’t recommend it. Cactus soil is gritty and doesn’t retain moisture well, so you would need to water a lot more often. It also lacks the nutrient-rich materials that Chlorophytum comosum needs.
Yes, African violet soil is a good choice for spider plants. The texture and pH level are ideal, plus it provides the perfect balance of nutrients.
Yes, you can use regular potting soil for your spider plant. Just make sure to buy a high quality brand that’s made for indoor plants, otherwise it may be too heavy.
