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

Worm Castings are nutrient-rich organic matter produced by worms that provide plants with essential nutrients.

Mycorrhizae are beneficial fungi that form a symbiotic relationship with plant roots, allowing the plants to absorb more nutrients.

Kelp Meal is an ingredient made from seaweed that delivers a rich array of nutrients and offers a sustainable alternative to chemical fertilizers

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

Bokashi is a composting method that converts plant waste into a microbially active, nutrient-dense soil enhancer through active fermentation. 


Feeds ~6 plants for 3 months


On watering day, top dress your plants by sprinkling a small handful (~½ cup) of Plant Food around the base of your plant. 


Water your plant as usual, which will help the beneficial nutrients and microbes travel to the roots.


Houseplants: repeat these steps once a month 

Herbs and Flowers: repeat every two weeks


Repotting day is also a great time for an extra boost. Add a large handful (~1 cup) to the base of the roots prior to planting. 

At Rosy, our entire supply chain has a net neutral carbon footprint!


We maintain an eco-friendly system (from production to delivery) by curating the most sustainable ingredients (like carbon negative biochar), packing processes, and shipping. 

In fact, every bag of Rosy helps captures CO2 from the carbon cycle.  

So, our Plant Food blend is a positive resource for your indoor garden and the environment.

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 blends are 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 soil into a carbon sink, which means it helps to remove CO2 from the atmosphere.
