Lawn Champion isn't a fertilizer – it's so much more!

Unlike traditional chemical fertilizers, our soil nutrition contains the right stuff for your lawn, without the risk of damaging or burning it. Lawn Champion feeds your entire soil system so that your plants can get what they need to grow longer, stronger roots.

Healthy Soil

Years of research trials in sustainable agriculture have shown that the healthiest plants spring from living soil systems with lots of beneficial microbes. Create a healthy microbiome with Lawn Champion.

Deep Roots

When you apply Lawn Champion, a Rachio controller can challenge your lawn to do more with less water while your roots and soil improve.

Natural ingredients for your lawn

We’re proud of the ingredients that go into the Rachio Lawn Champion treatment. Our non-synthetic superfoods feed soil’s living community without polluting water and air with nitrogen and other chemicals that overload our ecosystem.

Our soil nutrition is the key to total lawn transformation. Other natural treatments are pulled from the ocean and can compromise soil health with excess salt. Lawn Champion uses microalgae that is specially grown for use in soil. These micronutrients are more easily absorbed into your lawn because, well, that's what they’re made for!

A natural source of calcium carbonate, which boosts the natural soil biology and helps keep soil neutral.


Packed with nutrients to support the natural ecosystem of your yard. Includes vitamins and minerals like calcium, iron, magnesium, manganese, zinc, and more for superior yard health.
