Fertilizers, Soil Amendments & More

PJC Organic is the manufacturer of ProHealthy Turf organic fertilizer and distributor of other soil amendments. There are a lot of organic fertilizer products on the market, making it confusing for those looking for an All-Natural Organic approach to turf care. We have been evaluating products since 2002 and have come up with a core product list of organic fertilizer, taking the guesswork out of which products to use.

Build A More Efficient Organic Turf Care Program

You’re not the first landscaper to feel uneasy about the chemicals typically used to keep lawns thick and “healthy.” Nor are you the first to be afraid that offering organic fertilizer options will only cost more and yield lesser results. The longstanding problem lies in this: The fact that a product is “organic” doesn’t mean it’s good. Whether you’re looking for organic fertilizer you can offer your own clients, or you want help with seamless integration of organic turf care into your existing model, we offer the quality products and business resources you wished existed, but didn’t know were possible.

Organic Fertilization Programs for your Schools and Communities

Across the nation, implementation of green initiatives has become a major strategic goal for public and private institutions. There is pressure from the community, regulatory and advocacy groups, as well as, the legislature to make changes. Managing these conflicting desires can be challenging. We work with your maintenance team and/or service provider to tailor an All-Natural Organic Turf Care program that is easy to follow, effective, fits your budget, and is sustainable for generations.
