Organic Humate Soil Conditioner

Optimize is a concentrated organic humate soil conditioner that improves poor soil and increases fertility and vitality with organic matter. It begins working as soon as it’s added into the soil, and continues to release nutrients and enrich the soil over time. Optimize adds concentrated, fully decomposed organic matter (true humus) to create the soil environment for all plants to thrive.

I am a newcomer to John and Bobs but am fast becoming a true believer in their products. We have several projects that we are currently experimenting with using John and Bobs products and they are all showing great promise. I love the fact that you can’t hurt your plants with these products.
