FAQ

Why is Rosy Soil made without peat moss?

Peat moss has been a common ingredient in commercial potting mixes since the 1960s. However, it's obtained by extracting peat bogs, which are vital ecosystems that store carbon. At Rosy, we believe there's a better way. So, we've developed our blends with alternatives that are effective and sustainable.

How is Rosy different from other soils?

Rosy’s indoor potting soil is all-natural, peat free, and made from biochar. 

We’ve consciously sourced our ingredients not only because they’re great 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.

Read additional information about Our Mission.

How is Rosy Soil Earth friendly?

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, which means it helps to remove CO2 from the atmosphere.

Discover more about what we mean by Earth Positive on Our Mission page.

What is biochar?

Biochar is nature’s soil supercharger — a form of carbon that’s created by heating organic material (like wood or plant matter) in a low-oxygen environment.

Think of it as a sponge-like charcoal made for plants. It improves soil structure, helps retain water and nutrients, and creates a thriving home for beneficial microbes. It’s also incredibly stable, meaning it stays in the soil for hundreds (even thousands!) of years — all while capturing and storing carbon that would otherwise enter the atmosphere.

Unlike peat moss, which is strip-mined from delicate wetlands, biochar is regenerative and climate-positive. It’s science-backed, time-tested, and foundational to everything we do.

Can I add Rosy to my current potting soil?

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.

How many pots will a bag of Rosy Soil fill?

Our 8 Quart bag of Rosy indoor potting mix will fill:

4 to 6 medium 6" pots

Our 4 Quart bag of Rosy indoor potting mix will fill:

2 to 3 medium 6" pots

And unlike traditional indoor potting mixes, you won’t need to replace the soil every year due to compaction.

Soil Mates: Plants That Love This Mix

Rosy Plant Food is a gentle, all-purpose powerhouse that works for just about everything you grow

It’s perfect for houseplants, garden beds, and container veggies.

Indoor favorites like Monstera, Pothos, Snake Plant, ZZ Plant, Hoya, Fiddle Leaf Fig, Philodendron, and Peace Lily love the steady, natural boost.

Garden plants like Tomatoes, Basil, Lettuce, Kale, and Peppers respond beautifully to its slow-release nutrients and bioactive goodness.

It’s also great to mix in during repotting to help protect against transplant shock — thanks to mycorrhizae that support stronger root growth and better nutrient uptake.

Whether it lives on your windowsill or in your backyard, this blend helps your plants thrive naturally.

Smells like moist rich earth. NPK is only 1.12-0.22-0.64, though

I'm adding so many things to my plants I'm not sure what's doing what, but I certainly like the look and smell of this. It does occur to me it may not be a great idea to stick your nose in the bag and smell this, what with the fungi and all...

I like the added mycorrhizae, kelp and biochar, as these are items not present in some of my other soil amendments.

As a fertilizer, it's fine for plants that don't require much in the way of nutrients, such as most herbs. For vegetables, though, I don't think it has enough NPK. The NPK is only 1.12-0.22-0.64.

Works pretty well for my new rose bushes 🌹

I ordered this because we just planted 3 new rose bushes and I wanted to enrich my soil to help ensure my roses thrive. I applied this soil almost two weeks ago and my roses are ALL thriving after adding this around the top of my garden bed around my rose bushes. My roses are looking much better and healthier. All three rose bushes have several new buds that have started to sprout and I'm excited to see it come to full blossom. Our climbing rose bush is the one that needed the most extra care and it has already started growing a few new leaves and the beginning of new rose buds. My roses all seem to be flourishing with this plant fertilizer soil. Would absolutely recommend!!

For reference my shining moment rose bush was in the ground for close to two months before I added this around the base. My sweet fragrance and yellow climbing rose bushes were planted around 2 weeks before adding this soil. All of my roses have sprouted a surprising amount of buds since I added this soil. I'm very impressed with this soil. I simply sprinkling it around the base of my rose bushes and within 1-2 weeks I saw noticeable growth. I'm very happy with this fertilizer sold and would absolutely recommend it!

Easy to use

Many people don't know that plants need food too, not just water. This soil is very nice and loose, allowing for airflow and preventing compaction. Kelp and worm castings are like super food for plants.

To use, just sprinkle on top of your existing soil and water in. I used some of it for the fruit shrubs growing outside.

It seems well made, but I can't say I noticed a difference in my plants.
