About Us

Plant Health Care Systems of South Florida, (PHCSFL) is co-owned by Ian Maguire and Keith Weyrick.  Founded in April 2013 to fill a need within the lawn and ornamental pest control business, PHCSFL has seen steady growth as word of their successes and quality of work has spread.

Keith Weyrick's roots go deep in the green industry in south Florida.  A second generation nurseryman, Keith and his family owned and operated Quail Roost Nursery, Inc for 43 years in south Miami-Dade county.  They grew a wide variety of palms, trees and shrubs from 1 gallon to mature field grown specimens on 35 acres.  The business attained sales throughout the eastern US, Canada and the Caribbean, shipping plants as far away as Saudi Arabia.  Keith was the owner and manager of this business until 2003 when he decided to sell the business.  In 2004 Quail Roost Nursery, after 43 years, was closed.  The property was leased and is still in production to this day.


In late 1997 Keith purchased a franchised organic based lawn care business.  This business decision came as a result of input from his local landscape customers.  At the time, there was a tremendous lack of knowledge in the spray industry with regard to providing plant health care services.  January 1998 saw the opening of the Miami location for NaturaLawn of America.  Providing exceptional service and results in the lawn and landscape care industry, Keith's business grew.  He was soon providing nutritional and pest control services for many landscapers, landscape architects and designers.  Business grew to include over 300 residential and commercial accounts.  The Airport Corporate Center was their largest commercial account.  In 2006, after a major car accident Keith decided to sell the client base and take some time off. 


After a 4 year sabbatical, during which time Keith became a licensed US Coast Guard Captain as well as acquiring his UK Captain's license, he returned to the Green Industry.  Going to work for a large local lawn and ornamental spray company Keith first served as a consultant and eventually assumed the full time position of Customer Service and Quality Control Manager.  During this time he became acquainted with Mr. Ian Maguire.  Keith, again seeing a need within the spray industry for a knowledgeable and reliable plant health care company and Ian, seeing the same opportunity soon came to an agreement and Plant Health Care Systems of South Florida, LLC was born. 


Keith has been a Florida State Certified Pest Control operator since 2001 and is also certified in the Florida Green Industry Best Management Practices.  With over 15 years’ experience in the plant health care and pest control business as well as a lifetime of experience in the production of palms, trees, shrubs and groundcover Keith's extensive background brings a vast amount of knowledge to the company.  Keith's managerial experience includes running 2 businesses simultaneously with as many as 26 employees.
