Commercial and Institutional Applicators

The required BMP training can be obtained from:

DIY Recommendations

Healthy plants help prevent erosion and can remove some nutrients from stormwater runoff.  Applying just enough irrigation and fertilizer to maintain healthy active plants is the goal.  Apply fertilizers only when needed and only when the plants are actively growing.  Typical soils in Florida contain adequate phosphorus, don't use fertilizer with phosphorus unless soil testing indicates a deficiency.  The application rates on the bag are maximums, often less will be effective.  Homeowners should use fertilizers with a minimum of 30% of the nitrogen in slow release form.  The Florida Yards and Neighborhood handbook below contains excellent guidance.
