Protect our lakes and streams, fertilize sparingly and choose the right products.
June 1 - September 30
Just say no
- Avoid fertilizer that contains nitrogen or phosphorus from June 1 to September 30.
Know your bag
- Look for the three numbers that show the major nutrient content. 10-0-5 indicates (in order) Nitrogen - Phosphorus - Potassium. Select a fertilizer where the first and third numbers are equal or in a 2:1 ratio and the middle number is zero, or as low as possible.
Pump some iron
- Use Florida-friendly fertilizer products that contain iron and other micro-nutrients to green up your lawn during the summer
Veggies get a pass
- Nitrogen and phosphorus products can be used to fertilize vegetable gardens. Just avoid rainy days.
Get better dirt
- Fertilizer isn't always the answer. Give your garden a boost by adding compost, composted cow manure, perlite or other soil enhancements.
October 1 - May 31
Watch the weather
- Never fertilize when it's going to rain. Rainstorms wash away the fertilizer which finds its way into local lakes and streams.
Go slow by half
- If lawn and landscape fertilizers contain nitrogen, at lest 50% of the nitrogen should be slow-release. Other names for slow-release are "timed release," "controlled release" or "slowly available."
Twice is nice
- Fertilize only twice a year. Once in April, at the start of the growing season, and once in October to feed grass before winter dormancy.
- Slow-release fertilizers nourish lawns and plants gradually, over a longer period of time. That saves money and is better for the environment.
