John Perry is President/CEO Founder of Greene County Fertilizer Company, Inc. and its parent company, Bio Green USA, Inc.

Greene County Fertilizer Company produces a line of soil amending fertilizers and specialty fertility products for lawn, garden, turf care and agricultural use, humic acid, private label and custom blended products.

Bio Green USA is the manufacturer of the Bio Green® brand of high performance environmentally responsible fertilizers made available to individually-owned and operated lawn and landscape companies through the Bio Green Lawn Service brand business model for license and co-branding opportunities.

“Through both companies, we are able to be exactly who our customers need us to be. If their needs are high performance fertility products and consistently excellent results, then Greene County Fertilizer Company is the answer. For companies that need a strong brand, field technical expertise, a peer network, and a corporate partner for operational and marketing support, in addition to fertility products and results, then Bio Green® is the answer,” says John Perry, President/CEO Founder.

Both companies operate in their 30,000 sq. ft. manufacturing plant/corporate headquarters in Greensboro, Georgia and only the highest quality manufacturing practices are implemented.

Perry started in business with a Bio Green® spray service. He based his business model on not using conventional fertilizer. From there, he chose to focus on developing his own high performance fertility products for the professional service industry and began manufacturing products in late 2007.


The Lawncology® individual chapters were first written by John Perry and and published beginning in 2014 by Bio Green USA as a monthly topical series for Bio Green® Licensed Service Providers; these monthly articles continue to be published each month for Licensees.

Lawncology® is a method of both diagnosing common problems and understanding common practices in lawn care. These methods convert over into all professional plant care methods including row crop agriculture, arbor care, food production and ornamental plant care.

Lawncology® methods have been developed over years in the industry by constantly searching and discovering common threads that link human intervention or “over care” and soil and plant diseases that frequently plague our profession. These methods are in no way criticism of the way professionals have cared for their soil, plants and clients, but rather a new learning that will allow for some antiquated techniques to finally be left behind. Lawncology® looks at our plants and soils, weeds and pests,  as a cohesive unit rather than separate areas of study. This polarity of the “health vs disease” mentality begins to melt into a singular understanding of one not existing without the other.

Please join our growing Lawncology® community of green industry professionals who are changing the industry with these new tools. Contact us for more information about technician and management training within your company; on site trainings and workshops are available.
