We’re a team of plant people united by the crazy idea that good soil can change the world.
It’s why we’ve set out to create the highest quality products with the lowest possible environmental footprint.
To pull this off, we’ve brought together a world-renowned group of plant and soil scientists led by our Lead Soil Researcher, Jules.
Justin "Jules" Giuliano is an organic farmer and educator with a background in vermicompost and natural farming. Prior to joining Rosy, Jules managed an urban farm in Atlanta, studied regenerative agriculture at the Rodale Institute and won a Cannabis Cup for his cannabis cultivation.

has large grain size, coarse texture, and high silica content to support soil drainage.
Where's the peat?
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.
