Why John & Bob's?

John and Bob’s soil products are formulated to mimic how natural ecosystems build healthy, productive soil.

A natural ecosystem is rarely challenged by pests or disease and it does not require fertilizer. Rich soil is the key to the long term health and reliable beauty of a natural ecosystem.

John and Bob's feeds beneficial soil organisms with its unique blend of organic compounds, minerals and microbes. Our unique formulations use the same strategy that benefits self-sustaining plant communities all over the world.

The John and Bob's four product system of Optimize, Maximize, Nourish-Biosol and Penetrate, provides you with nature’s most powerful natural ingredients to infuse your soil with life. It's the easy, effective and organic way to make your soil healthy.
