Answer: Supporters of the new ordinance say that during the rainy season most of the nitrogen in the fertilizers washes from lawns and landscaping into lakes, streams, rivers and, ultimately, the bay. That promotes algae blooms, which suck oxygen from the water, making it unhealthy for fish, birds, sea grass and other wildlife.
The good news is that lawns don't need nitrogen during the summer months if you use it the rest of the year and if grass clippings, which decay and provide nitrogen, remain on the lawn after mowing.
And, many Florida soils are high in plant-available phosphorus so your lawn may not require any additional phosphorus in the form of fertilizer. I would not bother with fertilizer this summer. Leave the grass clippings on the lawn. As they decompose they will provide nitrogen to the lawn. And, if you really have to have nitrogen, you can apply a slow release next spring and it will get you through next summer.
