Fertilizing

  • Cool-season grasses should receive 3-5 applications of fertilizer per year..
  • Fertilizers consist of three main ingredients: Nitrogen, Phosphorus, and Potassium/Potash.
  • Nitrogen feeds the plants, fosters growth.
  • There are two types of nitrogen: Slow-release & Fast-release. We use a mixture of both types.
  • The fast-release nitrogen quickly nourishes the lawn, and over the following weeks the slow-release nitrogen is activated to continue to feed it.
  • Slow-release fertilizer uses microbial release, which means it takes the microbes in the soil to break down the fertilizer and release the nitrogen to the lawn. This assures steady, uniform growth.
  • Phosphorus develops the roots.
  • Potassium/Potash provides organic matter to help with water retention.
  • Cool-season grasses put on the most growth during spring or fall. During the summer, growth slows as the grass waits out the heat. When temperatures cool in the fall growth resumes more steadily.
  • The biggest feedings should be in late summer and fall.
  • If you don’t fertilize in fall, the lawn will need higher amounts of fertilizer in the spring.
