Fertilizing your lawn in Ohio is crucial for helping it grow healthy, green, resilient grass, but what nutrients help it do that? The three main macronutrients found in fertilizers are nitrogen, phosphorus, and potassium. These nutrients each play an integral role in helping your grass thrive throughout the year.

Nitrogen is the nutrient responsible for promoting lush greenery and supporting healthy grass growth. Phosphorus aids in energy transfer within plants and helps promote root development. Potassium helps strengthen your turf against stressors like diseases, insects, and environmental factors, such as drought and extreme temperatures. By providing these nutrients to your lawn, you can help it achieve its full potential!


Nitrogen promotes healthy growth and encourages a dense, vibrant lawn.

Nitrogen is one of the most important nutrients found in lawn fertilizers. It plays a crucial role in plant metabolism by encouraging chlorophyll production, which gives your grass its green color. Chlorophyll also aids in photosynthesis, allowing your turf to convert sunlight into food.

Nitrogen is essential for promoting healthy growth and encouraging a dense, vibrant lawn. Lawns with insufficient amounts of nitrogen may exhibit slow or stunted growth and thinning that leaves them vulnerable to weeds. Regular fertilizer treatments with this nutrient will keep your lawn lush and green throughout the growing season.

A lack of nitrogen can cause your grass to turn yellow or brown, resulting in an unattractive appearance that detracts from your property's curb appeal.

Phosphorus helps your lawn develop deep roots and energy transfer.

Phosphorus is another key nutrient found in lawn fertilizers. This nutrient plays a critical role in energy transfer within lawns, driving chemical reactions essential for their health, including photosynthesis. It's also known for promoting robust root development and overall plant vigor, leading to a stronger, lusher lawn. A deficiency in phosphorus can lead to weakened roots and stems, along with stunted grass growth.

Phosphorus is an important nutrient in many starter fertilizers due to its impact on early grass development. After all, it can help seedlings establish deep, robust root systems, ensuring successful germination and early growth.


Potassium is a nutrient in fertilizers that strengthens your lawn against stressors.

The third major nutrient found in lawn fertilizers is potassium. This nutrient is often referred to as the "strengthener" because it helps your grass build thicker cell walls and endure various stressors. Some examples of stressors that potassium can help your lawn fight off include:

  • Drought
  • Pest Infestations
  • Disease
  • And More!

Lawns deficient in potassium may be prone to issues such as thinning, browning patches, and weakened defenses against pests and diseases. With this nutrient in fertilizers, it can improve the overall health and resilience of your lawn, enabling it to better withstand stressors and maintain its beauty year-round.
