What our clients are saying

  • A golf course with a putting green, sand bunkers, trees, and a pathway under a clear blue sky.

    “I have been using Earth Medicine for the past year and a half in various applications, and the results have been impressive. My first experience with it was during a grow-in last year, where we applied it as a pre-plant. It far exceeded my expectations, leading to faster rooting and overall establishment. Earth Medicine has proven to be an excellent recovery product, promoting healthy recovery without the unwanted flash of excessive growth. We also incorporate it weekly into our green’s topdressing, using an 85/15 blend, and the root density this year has been noticeably more robust. I’m very satisfied with the results and plan to continue using Earth Medicine in my agronomic plan moving forward."

  • A person is holding a section of sod with roots, taken from a grassy area.

    "After Earth Medicine was applied to the surface of previously installed Sod, the area greened up and lines were fully grown in within 7 days. 5 stars"

  • A scenic golf course with green grass, trees, and a mountain range in the background under a partly cloudy sky.

    “Earth Medicine was readily available, easy to apply, provided consistent uniform application and did not have a foul odor. Most importantly, establishment of vegetation exceeding expectation was achieved with the use of Earth Medicine. The use of Earth Medicine at its recommended rates of application is very cost effective, and I look forward to its continued use in the future to provide quality turf at the Butte Country Club.”

    “As a first-time superintendent, it is difficult to trust the products that the former employees were using, especially if they weren't having success. Earth Medicine was on property when I first came to Julington Creek. I could get it blended in with my topdressing sand. Gamechanger. Through this process, my first growing season we had tremendous success filling in these areas, having consistent putting surfaces across all greens, which is something that could not have been said for quite some time at Julington Creek.”

Fast Results

Our Earth Medicine Greens Grade Fertilizer was applied to these greens in mid-September.

2 weeks later, the area was already showing signs of healing a repair.

We have invented a unique method of persevering the beneficial microbial life found in aerobic dairy manure compost.

Our organic microbes are shelf stable living biology that become activated when applied to the soil or turf surface.

As the turf is watered, the product begins to become activated with billions of living microbial life (Pseudomonas) which begin to release into the soil over time, building the health of the soil and root structures of the plants.
