Rainy Season Fertilizer Restrictions

The rainy season throughout much of Florida is June 1st through September 30th.  During this time, many areas adopt fertilizer restrictions to lessen the impact of nitrogen and phosphorus on our local ecosystem.  The following infographic outlines some basic information about the fertilizer restrictions and how they affect your landscaping practices.

Rainy Season in Florida

Did you know that much of Florida receives 80% of its annual rainfall during the summer months?  In fact, afternoon storms occur almost daily throughout much of the state.  When fertilizer is applied during the rainy season, it is likely washed into our local waterways.  “Nutrient pollution” negatively impacts aquatic habitats and is thought to increase algal blooms.  This is why many experts believe that fertilizer restrictions are a necessity during the rainy season.

Florida Red Tide

Red tide occurs when algae blooms at a higher rate than normal.  It is a nation-wide problem that affects tourism, natural habitats, and human health.  According to Florida’s Fish and Wildlife Conservation Commission, the species that causes most red tides in Florida is Karenia brevis (or K. brevis).  Unlike other red tide species, there is no direct link between nutrient pollution and the frequency or initiation of red tides caused by K. brevis.  However, once inshore, man-made nutrients can fuel their growth.  Many experts believe this is enough to enact fertilizer restrictions that protect our waterways.  

Fertilizer Restrictions & Lawn Maintenance

Fertilizer is a very popular.  It greens lawns and improves the growth of shrubs and trees.  However, healthy soil is essential to strong and healthy plants.  Regardless of fertilizer restrictions, choose landscaping practices that improve your soil and keep your plants resistant to disease and pests.

• Choose Florida native plants for your landscape.
• Use compost to enrich your soil.
• Leave lawn clippings on your grass to nourish your soil.
• Let your lawn grow long to improve root structure and natural defenses.

There are plenty of options that can be used throughout the year to keep your soil healthy.  Make these a part of your regular landscaping routine to improve its health all year long.
