A nutrient-rich ingredient made from seaweed and a sustainable alternative to chemical fertilizers.

A composting method that converts plant waste into a living, nutrient-dense soil enhancer through active fermentation.

Beneficial microorganisms that form a symbiotic relationship with plant roots, allowing the plants to absorb more nutrients.

Helps reduce waste in landfills by turning green waste and wood waste into a useful source of nutrients for plants.

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.

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.

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.

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.

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.

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

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.
