How Homeowners Can Help Reduce Red Tide

---

Red tide is a naturally occurring phenomenon, but excess nutrients from human activity—especially nitrogen and phosphorus—can make harmful algal blooms stronger and last longer. Homeowners play an important role in protecting coastal waters and marine life. 

Red tide is worsened by excess nitrogen and phosphorus.

Avoid fertilizing before heavy rain

Use slow-release or low-nitrogen fertilizers

Follow local fertilizer blackout periods

Never fertilize near waterways or storm drains
 

👉 Less fertilizer = fewer nutrients washing into the ocean.

Replace turf grass with native or drought-tolerant plant

Native plants require less fertilizer and water

Deep root systems naturally filter runoff

 Install rain barrels or rain gardens
Redirect downspouts away from driveways and streets
Permeable pavers reduce runoff into storm drains

 Choose phosphate-free detergents and cleaners
Avoid dumping chemicals into drains or yards

 Support local conservation efforts, participate in cleanups, and share information with neighbors. Community-wide action makes the biggest impact. 

 While no single action can stop red tide, small changes by many homeowners can significantly reduce nutrient pollution and help protect our coastal ecosystems for future generations.
