What is the Best Soil Mix for Spider Plants?

You love the display of the spider plant in hanging baskets or pots. They are a natural plant that grows in the soil of their tropical home However, they can be seen in pots.

In order to keep the spider plant healthy and beautiful, you need to replicate the characteristics of the soil that is naturally found.

Organically rich, well-draining potting mix is the ideal potter’s soil for spider plants. Vermiculite, perlite, coconut coir, or sand may be added to the general-purpose mix to increase drainage and aeration. It is essential to add sphagnum peat moss, worm casting or compost, to enhance nutrition value.

The Best Soil for Spider Plant

The first and most important thing to remember is that you should not plant the spider plants in soil that is used for gardening. It could grow too large and cause your spider plant to drown.

The most unpleasant thing is to be faced with multiple instances of root decay.

Therefore the most suitable dirt for plants like spiders should comprise a mix of different materials. The soil matrix should be able to meet the needs of spider plants to aerate, drain, and fertility.

The combination of these materials will keep a significant amount of moisture without becoming wet or soiled.

Keep this in mind when you plant the web-based plant can benefit greatly from fertile, well-drained soil.

Select loamy soil for the base to create a soil mix that is perfect and then add all the ingredients.

For me I prefer a general-purpose potting mix for the base.

A great mix can be created by adding a small amount of perlite, pumice or vermiculite to the base to increase air circulation.

I also like adding an extra scoop of compost, worm castings, and coffee grounds in order to increase the nutritional value for your garden.

Components of Spider Plant Potting Mix

Every ingredient included in your spider plant’s potting mix must have a distinct purpose. Therefore, you should consider the following questions:

  • Does the ingredient enhance soil’s nutritional value?
  • Does it aid in soil drain properly?
  • Does it increase capacity to retain water?
  • Does it increase bulk? Or will it add weight?
  • Does it improve aeration in the soil?

I’ve had the pleasure of caring for and owning spider plants for a long time. My experience has taught me that the most effective components to incorporate the growth of your spider plant medium are:

Coconut Coir

Coconut Coir is the fibrous product from process industries that deal with coconut. Since it is easily available, pH-neutral, and light, it makes an ideal ingredient for potting mixes for spider plants.

Due to that coconuts are plentiful, the cost of a coconut coir bag is a bargain. (Check the most recent cost at Amazon right here).

Certain sellers of coco coir might make use of misleading names. Many refer to it as Coir dust, coir fiber pith, coco-peat, or coir-peat.

Whatever you want to call it adding coir to your potting mix can have a variety of benefits:

  • It helps to retain soil moisture. Coir is able to hold up 30 percent more water as peat moss.
  • Coir is also much easier than peat moss in terms of rehydrating after drying
  • Aeration and air porosity are guaranteed even when the soil is damp
  • It doesn’t alter soil pH since it’s not acidic as peat moss is.
  • It’s sterile and free of weed seeds.
  • It improves the drainage and texture of clay soils.
  • Coconut coir can be used to line the hanging baskets of your spider plants
  • It is possible to use the horticultural coil instead of or in conjunction with Sphagnum peat moss
  • It is often referred to as coco-peat, coir-peat Coir fiber pith, coir dust, or other similar brands.
  • Coir is believed to improve resistance to root rot disease such as pythium rot (Source: Journal of the American Society for Horticultural Science, JASHS)

But, it’s low in nutrients when it is compared to peat moss. A high amount of coir can make the potting mix become compact.

In this regard to achieve that, the proportion of coconut coir used in the potting mix must not be more than 40% in the overall composition.

Sphagnum Peat Moss

Peat moss has proven to be an absolute blessing for gardeners since its introduction at beginning into the 18th century. It’s an excellent supplement to your spider plants pot mix. It’s not without reason:

  • Sphagnum peat moss is superior in its capacity to manage moisture
  • It is a reservoir of essential nutrients that are otherwise be flushed out by irrigation water.
  • It improves the texture and consistency of the potting soil.
  • It is a great way to improve soil pH balance as well as the nutritional content of soil
  • Helps to aerate the soil

You can clearly see that peat moss is the most sought-after potting mix. Nearly every gardener with a good knowledge has an inventory of peat moss sphagnum in their garden.

In addition, it is the fact that it’s cheap and light.

The best potting soil for spider plants must be a soft texture It should be soft and rich and evenly moist.

Peat moss is a great option for each of these aspects that affect the growth medium. What amount of peat moss do you need to put into the soil for potting?

Peat moss is acidifying and has an effect. Therefore, it is recommended to be careful when using it as spider plants require a neutral pH soil to flourish.

Peat moss shouldn’t account in more than 2/3 of composition of the entire mixing for the best results.

Perlite vs. Vermiculite

Perlite is an organic part of potting soil. It is composed of white specks that are round and volcanic glass that is water-based. I use it primarily to help aerate my spider plant pot mix.

It is important to note that vermiculite is a viable option however perlite is better. Both of these ingredients contribute to keeping soil water in place.

Perlite On contrary is more porous and lets water be able to drain more efficiently.

Apart from the advantages of aeration and retention of water Perlite is also naturally pasteurized and pH neutral.

It’s also extremely lightweight! Perlite is supposed to comprise 10% to 20 percent of the potting mix.


The spider plant hates being “wet.” If it is left in the damp dirt for long enough, the root rot disease can develop. This is not an ideal thing.

If you aren’t able to access to perlite or vermiculite or perlite, you can use coarse sand. It’s the cheapest Aeration medium. It also helps prevent from compaction in the mix of potting.

Make sure it’s light but not coarse enough to break up soil clods. If it is then the coir can prove extremely beneficial.

This is because it increases the retention of water of potting mixes made from sandy soil.

The Ultimate Spider Plant Potting Mix Recipe

Spider plants are durable and adaptable. They thrive in many pot mixes.

But, when you bring the spider plants home, the mix of potting soil could be dry or deficient in nutrients.

This is why the most effective spider plant mix recipe for potting is vital. It is suitable for making a new plant or repotting an existing plant.

Make sure to repotte the spider plants every two to three years.

Two recipes that I have used to make spider plant pots:

1. Recipe number 1:

  • 3 parts organic potter’s soil. Miracle-Gro Indoor Potting Mix (Check the most current prices at Amazon right here) is frequently regarded as the best standard for well-draining potting mixes.
  • One part of perlite. You could make use of vermiculite, coarse sand or pumice instead of perlite.
  • A few pieces of coconut coir, or orchid barks
  • A few handfuls of compost, earthworm castings or sphagnum peat moss

Second recipe:-

  • Two parts of succulent mix. There are numerous and readily available cactus soil mixtures (Check the most current prices at Amazon right here). This ingredient is essential to ensure aeration and nutrition.
  • 1 part coconut coir or peat moss
  • One part of high-quality compost
  • It is possible to sprinkle earthworm castings, too.

The potting mix used in both recipes can hold the moisture more time than the spider plant need.

In the end, you’ll have to add vermiculite, perlite, coarse pumice, or sand to make up for. In any case coconut coir is the best choice for a component.

It is recommended to add a few ounces of earthworm casting or compost to give your garden a dose of organic and richness. Sphagnum peat moss is a great way to tie everything together.

In general it is essential to thoroughly mix the mixture to ensure a uniform dispersion of the nutrients as well as to ensure aeration.

Make sure to test the pH of your growing medium at the end of the process.

Peat moss, as an example can alter the soil’s pH towards the acidic side.

If that is the case ensure that you include horticultural limestone if required to correct the imbalance in pH.

Homemade Soil Mix for Spider Plants

Make your own growing mix for the spider plant in the same manner as you would prepare commercial potting mixes.

It must be uniform light, easy to carry, and simple to use. Naturally, the product must offer sufficient drainage.

You should fine-tune your potting mix’s capacity to retain water and nutritional content, density, and even the texture. Most likely, you have everything you require to do that.

Additionally, sphagnum peat-moss perlite, compost sand, and coir are easily accessible in United States.

Basic Potting Soil Recipe for a Spider Plant

Finding the perfect balance in the mixing of the ingredients for the potting mix is crucial. Here’s a simple DIY recipe that you can follow:

Organic Material

At at least a quarter of the potting mix must comprise organic materials. The nutrients-reach elements are part of this portion of the medium for potting.

It is possible to use maturing compost or sterilized manure, or earthworm castings as amendments.

The organic materials are mixed and mixed and. The nutritional composition in the mix can be enhanced by the diversification.

In the end, you don’t need a medium for growing that is rich in potassium, but is low in nitrogen or the phosphorus.

Composted wood chip is my most favorite organic ingredient. By increasing the size of soil’s pores it increases the flow of air and also helps in drainage.

To help in the breakdown of wood chips that have been composted, include some alfalfa meal and blood meal.

Of course compost is the most important organic richness component. Its ability to retain water is awe-inspiring.

Additionally, it contains millions of beneficial microbes that help keep the spider’s roots plant healthy.

Nutrient and Water Retention

Soil that drains well, like loam sand, may quickly disappear in water and nutrients. This can be exacerbated when you water the soil from the top.

This is not the case anymore with coconut coir or peat moss. They are a part of the ability of potting mixes to hold moisture and nutrients for a long time.

Peat moss, as well as others water retention tools may cause acidification of the soil’s pH.

In the end, you can add limeing agents, like limestone to counteract this result.

A component in the mix must include coco coir, peat-moss or additional “water-holding” components.


Drainage is crucial in spider plant. The soil used for potting should be well-drained in order to avoid flooding or humid conditions.

To do that, you’ll need to include at least one of the ingredients that boost drainage.

The most effective ones are:

  • Perlite
  • Vermiculite
  • Pumice
  • Sand that is coarse

In addition to improving drainage, they also help to aerate the soil. They also break down soil clods and allow roots to grow and penetrate easily.

What is the Ideal Soil pH for Spider Plants?

Spider plants prefer relatively neutral soils that is in between the 6.0 up to 8.0 pH spectrum. The good thing is that they are able to tolerate slightly alkaline or somewhat acidic soil.

But, they won’t flourish in soils with pH levels at the extremes. The majority of organic potting mixes are between the two ends of the range.

Other ingredients, like coco coir and peat moss may cause soil pH to shift toward the acidic side. Peat moss, for instance is a soil with a moderately acidic pH range of 3 to 4.5.

This means that adding only 25 percent peat moss in the entire volume of potting mix could cause soil pH to reach unacceptably high levels.

If your pH meter shows an amount lower than 6.0 it is time to act immediately. I strongly suggest that you make use of limestone.

In the event that your soil appears too acidic (above 8.0) then you could add more sphagnum peat moss , or iron/aluminum sulfurate.

Why Does pH Matter?

Be aware of the pH of the potting mix for your spider plant is crucial. This is due to the amount of essential nutrients available particularly iron.

In the event that soils are too acidic and acidic, the quantity of iron is much less which can lead to deficiency.

A spider with iron deficiency will likely be affected by interveinal yellowing or paleness of leaves. It is essential to get the soil limed in order to neutralize the acidity.
