For soil mix that comes with an affordable price tag, count on the Miracle-Gro Potting soil. The mix contains coco coir, sphagnum peat moss, and perlite to create a lightweight soil that will not compress over time, allowing your spider roots to develop. Moreover, the soil mix has fertilizers designed to get freshly transplanted seedlings off to a good start and keep the spider plants fed for up to 6 months.

I noted that the fertilizer mixture on the soil mix usually promotes multiple leaves on my spider plants, which results in more bushy spider plants. Conversely, this is a dry potting mix. Still, since dry peat moss might be difficult to moisten at first, it contains a wetting ingredient that allows it to absorb moisture easily after the initial watering.


  • It comes with an affordable price tag.
  • It contains a wetting agent which helps with initial moistening.
  • Effective for up to 6 months
  • It drains quite well.


  • The additional fertilizer is synthetic.

Factors to Consider Before Buying the Best Potting Soil for Spider Plants

1. Drainage

When buying the best soil for spider plants, consider the drainage capability. A clay-heavy soil has no water drainage capacity, whereas sandy and silty soil doesn’t retain water.

The spider plant prefers well-draining soil with a balanced blend of other components. The soil must retain adequate water without getting soaked or soggy.

2. Nutrition

Spider plants are usually voracious feeders. For them to thrive well, they require dense, nutrient-rich soil. If you pull a Spider plant from the soil, you will see that it has long, thick roots. Along with acting as an anchor, these thick roots show that your plant needs more nutrients than plants with thin roots.

Spider plants require nutrient-rich growth conditions to thrive. Otherwise, they are likely to die if they do not obtain enough nutrients from the soil.

3. pH Value

Spider plants usually prefer slightly acidic soil. The ideal pH range for spider plant soil mix is 6.0 to 7.5. This pH level reduces the presence of fluoride, which is harmful to spider plants.

When the spider plant is exposed to fluoride for a long time, the tips of its leaves become brown. Conversely, if the soil is excessively acidic, you can conveniently add ground limestone to raise the pH; on the other hand, if it is overly alkaline, you can add peat moss to lower the pH.

4. Sterilization

It’s important to use a sterile soil mix to help prevent the spread of diseases and pests. Look for soil that has been pasteurized or sterilized to kill any harmful bacteria or fungi.

5. Organic Matter

When a soil mix is labeled organic, it means it passes USDA guidelines for chemical-free manufacture. The Organic Materials Review Institute (OMRI) has also certified it as containing solely natural (no synthetic or chemical) ingredients.

Spider plants benefit from organic matter, such as compost or well-rotted manure. This helps to improve the soil structure and add nutrients to the soil.

6. Moisture Retention

Another factor to consider when looking for the best potting soil for spider plants is moisture retention. Consider the soil’s ability to retain moisture. Besides, keep in mind that the quantity of water in the soil is a good indicator of its health. Succulent soil does not have much moisture, but a standard potting mixture does.

Therefore, the ideal soil mix for your Spider plant falls in between. Avoid overwatering since it can lead to waterlogging and excess moisture. If your filtered garden soil is too dry to retain moisture, you can boost its moisture retention capacity by adding organic components such as coco peat, worm castings, and compost.

7. Aeration

Aeration inside the soil is quite crucial to the health of your plant. If you want your Spider plant to stay healthy, ensure the soil has enough airflow. Most people are primarily concerned with fertilizer and watering, forgetting the need to keep the soil well-aerated.

Remember that a tightly packed soil mix is an ideal breeding ground for diseases such as root rot, fungal growth, etc. On the other hand, well-aerated soil allows oxygen to circulate freely throughout the root system, promoting the development of healthy bacteria and microorganisms. Furthermore, it will enable proper moisture retention by allowing water to soak in. Therefore, ensure the soil mix you’re growing your Spider plant has enough aeration to promote healthy growth.

Steps on How to Repot Spider Plants?

Repotting spider plants is quite easy; follow the steps below:

Steps on How to Repot Spider Plants

Image Source:

1. Start by removing the spider plant from its original container

2. Remove any excess soil from the roots and inspect them carefully. If you see any signs of root damage, remove them before repotting.

3. Before repotting your spider plant to a larger pot, clean the plant thoroughly.

4. A pot one size larger than the current one is enough. Besides, ensure the pot you’re using has enough drainage holes.

5. Place the plant at a height where you can bury the roots in potting soil.

6. Water the plant after repotting to allow the potting soil to settle properly.

Frequently Asked Questions on the Best Potting Soil for Spider Plants

1. What are the signs that you’re using the wrong soil mix for spider plants?

If your spider plant is not growing properly or your leaves are yellowing or withering, it is because you are using the incorrect soil mix. Generally, spider plants require sandy loam soil with adequate drainage and enough organic matter.

2. What kind of container should spider plants be potted in?

Grow in a potting mix that is soil-based and well-draining. Spider plants prefer consistent moisture though it shouldn’t be too dry or too wet. Keep the Spider plants in bright to mild, indirect sunlight; avoid direct sunlight because it can burn their leaves, resulting in brown tips and patches.

3. Should I repot spider plants in shallow or deep pots?

Get a little larger pot than the one it’s currently in. The spider plant is happiest when its roots can take up the soil area. Besides, the plant wants to be able to grow.
