A new law in New York state that takes effect on April 1, 2026 places strict regulations on the use of lawn fertilizers. The law prohibits the application of fertilizers containing phosphorus, requires a 20-foot buffer from waterways, and bans fertilizing before April 1st each year.

Why it matters

The new 'Fertilizer Law' aims to protect New York's waterways from chemical runoff that can harm aquatic ecosystems. However, the regulations have drawn criticism from some homeowners who see them as government overreach into private lawn care.

The details

Under the new law, New Yorkers must purchase fertilizers with a '0' in the middle of the N-P-K ratio, indicating no phosphorus content. Fertilizing is also prohibited within 20 feet of any waterway. Additionally, it is illegal to apply any lawn chemicals before April 1st each year, regardless of whether the lawn actually needs fertilization.

  • The 'Fertilizer Law' takes effect on April 1, 2026.

What they’re saying

“Before buying lawn fertilizer, check the bag for a set of three numbers showing the percentage of nitrogen, phosphorus and potassium. Buy a bag with a "0" in the middle.”

What’s next

The DEC will be enforcing the new 'Fertilizer Law' starting April 1, 2026, and homeowners who violate the regulations could face fines or other penalties.

The takeaway

While the 'Fertilizer Law' aims to protect the environment, some New Yorkers see it as an overreach by the government into private lawn care. The new regulations will require homeowners to carefully consider their fertilizer choices and application timing to stay compliant.
