The Best Soil Mix for Spider Plants – The Essentials
Spider plants do best in potting mix that holds moisture yet also drains well. They prefer a soil mix with a slightly acidic pH, in the range of 6.0-7.0. A soil mix containing 1 part peat moss/coco coir, 1 part perlite, and 4 parts pine bark fines is an excellent mix for Spider plants.
The Role Soil Plays in Plant Growth and Health
We all know healthy soil is key for plant growth, but what role does it actually play? Well, soil helps plants access the nutrients, oxygen, moisture, and other elements they need to grow and thrive. The right soil will support a plant’s roots and ensure conditions are optimal for that specific species to flourish.
Additionally, soil requirements will vary based on the plant you are trying to grow. For example, some plants need a particular pH level, while others have specific moisture requirements.
This is why using the correct soil type is so vital for your houseplants. With the proper foundation, they can grow strong and live for years. However, with the wrong soil, they may develop problems or struggle to thrive.
Signs You’re Using the Wrong Soil Mix for Spider Plants
As the so-called ribbon plant enjoys well-draining soil, denser soils may make it difficult for yours to grow. There are a few other signs that your spider plant isn’t in the right soil. Here are a few indicators to look out for when considering a new soil mix for your spider plant.
- The plant develops root rot at the base
- Leaves turn black, brown, or yellow
- Foliage develops spots
- Leaves droop, curl, or fall off of the plant
Many of these are common symptoms of an overwatered spider plant or inappropriate environmental factors such as the ambient temperature and humidity. This is why well-draining soil is essential to achieving the plant’s preferred living conditions.
The Fundamentals of Well-Draining Soil for Spider Plants
Now, it’s so important for spider plants to have good drainage because denser soils can cause their roots to drown. The plant enjoys a slightly moist environment, but sitting in soggy soil can lead to various issues.
For this reason, it is wise to steer clear of dense soils like gardening soil. Organic potting soil for indoor plants will work well. However, for the best possible structure for these plants, adding ingredients like perlite and pumice will make a significant difference.
Which Soil pH Level Is Best for Spider Plants?
Spider plants enjoy a neutral soil pH, but they will tolerate soils ranging from slightly acidic to a touch more alkaline on the pH scale. The ideal pH level for this species will fall between 6.0 and 7.2.
Soil Considerations Based on Plant Pot
The success of your potting soil will depend on the type of pot or planter you’re for your ribbon plant. This is because some containers retain moisture better than others.
A plastic container with a drainage hole allows this species to get the moisture and flexibility it needs for its roots to grow. Since plastic retains moisture more than other planter materials, well-draining soil is essential for this plant’s ideal living conditions.
Soil Considerations When Repotting Spider Plants
You should repot your spider plant in its preferred soil: a well-draining, organic mix with a neutral pH level. Remember, always aim to repot your spider plant in the spring or summer, as it should remain dormant during the winter months. You will also want to repot a few days after watering to help it adapt better to its new environment.
Instead of using a standard potting soil alone, you may want to add a few extra ingredients when repotting your plant. Read on to learn some of the add-ins the ribbon plant will love in their soil mix.
The Ultimate Spider Plant Potting Mix Recipe
While this is an adaptable and forgiving species, there are a few things to keep in mind when it comes to the best soil mix for spider plants. For example, cactus or succulent soil alone may not be best for spider plants. However, they may do well with a bit of orchid bark at the base of their pot for maximum drainage.
If you’re looking for pre-mixed soil for this species, here are some good options (each can also be supplemented with a light fertilizer suitable for Spider plants). Remember, some of these may work even better with added ingredients for optimal drainage, aeration, and nutrition.

However, it may be helpful to understand the components that most ribbon plants enjoy. That’s why we’ve developed our recipe for the best homemade soil mix for spider plants. Here are our suggestions for achieving the perfect conditions for this species.
- Well-draining, organic potting soil
- Orchid bark or coco chips
- Charcoal, pumice, or perlite for drainage, if not included in the potting soil
- Compost for added nutrients
For this recipe, you will start by adding a handful of orchid bark or coco chips to the base of your planter to maximize drainage.
Next, you will add a layer of potting soil mixed with your drainage ingredient of choice and a handful of compost if it is available to you. This will ensure a nutrient-rich environment and further optimize drainage.
Finally, place the plant’s root ball on top of this soil layer and fill in the sides and top with the same mixture. You can also add a small amount of worm compost or castings to the top of the soil for even more added nutrients.
Also, even though spider plants aren’t considered toxic to humans, it’s prudent to wear gloves throughout any extended houseplant care project.
