Fertilizer is the largest pollutant in stormwater runoff and spawns large algae blooms, nutrient overload, and hypoxic (or Dead zones) in ponds, lakes, and rivers. Protect water from fertilizer:
– Apply fertilizer according to instructions
– Use only the amount needed
– Sweep stray fertilizer back onto the lawn or garden to keep it out of the gutter.
– Switch to native landscaping which require less fertilizer and water for their upkeep.
