Our carbon-neutral blend helps fight climate change and is perfect for all types of houseplants, including foliage plants, flowers, ferns, herbs, and tropicals

Plastic neutral packaging in convenient sizes for indoor plant parents

A horticultural charcoal that increases nutrient retention, hosts beneficial microbes, and stores carbon in the soil.

A byproduct of the mulch industry which enhance soil structure and improve aeration.

A naturally occurring volcanic rock that is lightweight and porous, helping to improve soil drainage and aeration.

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

Nutrient-rich organic matter produced by worms that provide plants with essential nutrients.

Has large grain size and coarse texture to support soil drainage.

Orchids are epiphytes—they don’t want to live in a soggy bog. Peat bogs are also vital carbon sinks, so we skip the peat and use sustainable, regenerative ingredients instead.

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.

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.

Orchids like to hang out on trees in the wild, not in dense, soggy dirt. Our mix mimics their natural habitat—super airy, chunky, and alive with microbes.

Absolutely. Refresh your old mix or go all-in with Rosy for the full tropical VIP treatment.
