FERTILIZER-FREE SEASON:
Rainy Season is here — and that means it's time to protect Biscayne Bay! No fertilizer may seem like a small step, but it makes a big difference for our bay, our wildlife, and our island home.
Here's your Bay-Friendly Checklist:
🚫 Skip the Fertilizer – No nitrogen or phosphorus fertilizers from May 15 – Oct 31.
📏 Keep Your Distance – Maintain a 20-foot fertilizer-free zone near seawalls, canals, and storm drains.
🌧️ Watch the Weather – Never apply fertilizer before heavy rain or onto sidewalks and streets. Sweep up any spills.
Rain washes fertilizer into our canals and Biscayne Bay — fueling algae blooms and stressing seagrass. Seasonal County Fertilizer Rules are now in effect. We're the Healthy Heart of the Bay — let's protect it together.
