Earth Positive Indoor Potting Mix

To make an indoor plant potting mix, you need to create a blend of ingredients that improve soil aeration, drainage, and nutrient retention. 

This can include:

Biochar

Compost

Worm castings (earthworm castings)

Coarse sand

Pine bark

Perlite

Vermiculite

Pumice

Coco coir

Peat moss

Synthetic fertilizer

But some ingredients, like sphagnum peat moss and synthetic fertilizer, can be unsustainable and harmful to your indoor container plants. 

That’s why it’s better to buy eco-friendly bagged soil (not the traditional ones in garden centers) professionally blended for potted plant growth, like Rosy.

No, you shouldn’t use regular potting soil or garden soil for indoor plants. 

These soils are fine for outdoor plants and vegetable gardens. But topsoil or potting soil containing sphagnum peat moss can cause soil compaction and root rot in container plants. 

Plus, they may house harmful insects like fungus gnats (gnats) and mites.

That’s why it’s better to use a houseplant potting soil, like Rosy indoor potting mix. It’s a fertile and airy potting mix with well-draining soil — perfect for potted plant growth.

Check these two things when looking for the best potting soil for indoor plants:

Ingredients: Look for amendments that add nutrients and enhance soil structure. However, avoid mixes with sphagnum peat moss (even "sustainably harvested" peat) and other unsustainable ingredients.

Type of soil: Look for a houseplant mix that meets your plants’ needs. You can find options for high water retention (moisture control), seed starting, and other indoor plant potting soil requirements.

Being mindful of these aspects can help you choose the perfect indoor plant soil mixture for your garden.

Rosy’s indoor potting soil is all-natural, peat free, and professionally blended. 

We’ve consciously sourced our ingredients not only because they’re perfect for your plants but also because they’re good for our planet. 

Unlike traditional potting soil ingredients that are environmentally taxing, our biochar potting mix only contains natural and carbon-negative amendments.

We use carbon-negative, organic ingredients to create the best indoor plant potting mix.

Typically, these organic materials are sent to a landfill, where they release methane and CO2 — two potent greenhouse gases. But by redirecting these organic materials from landfills and stabilizing their carbon structure, we prevent the release of those greenhouse gases.

Essentially, we turn our house plant soil into a carbon sink. So, it removes more CO2 from the air than it releases — making our soil Earth Positive.

Peat moss is a soil amendment that facilitates moisture retention. 

However, its extraction from peat bogs harms our planet. In fact, the peat moss industry accounts for 5% of total global CO2 emissions. (More than twice the airline industry!) 

Plus, it can lead to soil compaction as it decomposes over time. 

So, we’ve opted for planet-friendly ingredients like biochar and compost to stand in for peat in our indoor potting mixes.

Yes! You can add Rosy to your current houseplant potting soil — whether it’s an inorganic or organic potting soil mix, cactus or orchid mix, or otherwise. 

Doing so will help you refresh your old soil and revive its benefits for plant care. 

Alternatively, you could directly replace your current houseplant soil mix with Rosy. 

You can use Rosy indoor soil for plants like: 

Tropical plants (monstera, money tree, ZZ)

Philodendron

Pothos

Trailing plants 

Ferns

Succulents (snake plant, aloe vera)

Why is it the best soil for these plants?

Rosy is a well draining potting soil, offering an optimal balance of drainage and moisture retention. Plus, it’s fertile and supports beneficial microbes, which help your indoor plant thrive.

One 8 qt. bag of Rosy indoor pot mix will fill:

4 to 6 medium 6" pots

2 to 4 large 8" pots

And unlike traditional indoor potting mixes, you won’t need to replace the soil every year due to compaction. So, it’s the best indoor potting mix for your indoor garden.
