Pennsylvania’s fertilizer law brings a major change to lawn care by banning phosphorus in most residential fertilizer products and limiting nitrogen applications to 0.7 pounds per 1,000 square feet. Gardeners who grab a bag of fertilizer without checking the label may soon discover that the old routine needs a little updating.

Thankfully, a healthier lawn does not require dumping extra nutrients into the soil like a chef tossing salt into a soup pot. Smart timing, soil knowledge, and the right fertilizer choices can help Pennsylvania lawns look great while protecting streams, rivers, and local ecosystems.
