PWD Reminds Residents to Apply Lawn Fertilizers Responsibly Application Prior to April 1 is Prohibited

As spring approaches and residents begin preparing their lawns for the growing season, the Plainview Water District (PWD) is reminding the Plainview-Old Bethpage community to follow Nassau County’s “Fertilizer Law,” which prohibits the application of lawn fertilizers before April 1 each year. Through its Preserve Plainview initiative, the District continues to educate residents on responsible lawn care practices and the importance of protecting the local aquifer and surrounding waterways.

“Spring is an exciting time for homeowners as lawns and landscapes begin to come back to life,” said PWD Commissioner Marc Laykind. “However, it’s important to remember that fertilizing too early can do more harm than good. Following Nassau County’s fertilizer regulations helps protect our drinking water supply and ensures that nutrients are applied only when lawns can properly absorb them.”

Under Nassau County’s Fertilizer Law, fertilizers may not be applied before April 1 or after November 15 each year. These seasonal restrictions help reduce nutrient runoff that can occur when fertilizers are applied while the ground is still frozen or before grass is actively growing.

The District encourages members of the POB community to apply only the minimum amount of lawn chemicals necessary and to carefully follow instructions listed on product packaging. Proper storage of fertilizers and lawn chemicals is also essential. Products should be kept in sealed, leak-proof containers and stored in cool, dry locations to prevent spills and environmental contamination.

“Timing plays a major role in responsible lawn care,” said PWD Commissioner Andrew Bader. “When fertilizer is applied before the ground has fully thawed, rain or snowmelt can wash those nutrients away before they benefit the lawn. Waiting until the proper time not only supports healthier grass but also helps prevent excess chemicals from reaching storm drains, waterways, and ultimately our groundwater.”

Residents looking for environmentally friendly lawn care options may consider organic fertilizers such as cottonseed meal, bone meal, or manure. In addition, biodegradable insecticides that naturally break down into harmless substances within a few weeks can offer an effective alternative to traditional chemical treatments while helping protect the aquifer.

“Every decision we make in caring for our lawns has the potential to impact our environment,” said PWD Commissioner Michael Chad. “By choosing responsible products and following the county’s fertilizer regulations, residents play an important role in safeguarding our groundwater. Protecting our aquifer is a shared responsibility, and small actions can make a meaningful difference.”
