How does 4-H work in St. Lucie County?

St. Lucie County 4-H is a UF/IFAS educational program for youth ages 5 to 18, built around clubs, county activities, group projects, special interest clubs and state events.

The St. Lucie County 4-H page says members, parents and volunteer leaders learn and work together, and that the program aims to build life skills such as leadership, communication and problem solving while members gain knowledge in project areas including STEM, healthy living and citizenship. The St. Lucie County 4-H team splits its work between positive youth development with volunteer opportunities and a second track covering 4-H water programs, embryology and general support.

The page links the tools a St. Lucie County family uses to join and plan: 4-H Online for enrollment, Florida 4-H, the St. Lucie County Fair Standards of Excellence for 4-H projects, Florida 4-H Summer Camp, a year in advance program calendar and a program handbook for the 2025 to 2026 year, and a St. Lucie County 4-H Spotlight. Volunteer leaders are part of the model: the county's extension page lists a Leaders and Volunteers section and a 4-H Advisory Committee under 4-H Youth Development. Questions go to the main office line, (772) 462-1660, listed on the 4-H page footer.

What does the St. Lucie County extension office offer farms and green industry workers?

The Commercial Horticulture page for St. Lucie County lists training and technical support for sod production, plant nurseries and green industry professionals; pest scouting to reduce pesticide use; diagnosis of turfgrass problems; education on water conservation, water quality, nutrient management, safe pest management and pesticide use; commercial pesticide applicator trainings and courses for CEUs; and the Green Industries Best Management Practices course, known as GI-BMP, which promotes responsible use of fertilizer, pesticides and irrigation.

Who runs and pays for extension in St. Lucie County?

Extension in St. Lucie County is a partnership: the University of Florida administers it, and the St. Lucie County Board of County Commissioners decides each year how much the county contributes.

The UF/IFAS St. Lucie County subject matter directory page traces the national Cooperative Extension Service to the Smith-Lever Act of 1914 and describes it as a partnership among state land grant universities, the U.S. Department of Agriculture and county governments, which share in planning, financing and operating extension programs; in Florida, the service is administered by the University of Florida.

State law fills in the county's role. Section 1004.37, Florida Statutes says the Florida Cooperative Extension Service is administered through the University of Florida and supported programmatically by the University of Florida and Florida Agricultural and Mechanical University in collaboration with county governments. In each county the board of county commissioners annually determines the extent of its financial participation, and that participation influences the number of county extension agents and clerical staff and the scope of the local program. The statute also gives the board the power to approve or disapprove persons recommended for extension positions, and lets a county ask by resolution for a list of three qualified candidates for each opening, a power that applies to the St. Lucie County board as to every county board in Florida.
