Tips For Fertilizing the Grass

It is advisable to fertilize the grass in spring and fall. In the spring, fertilizing will help the grass recover from the winter and grow stronger and healthier during the summer. In the fall, fertilizing will help strengthen the grass over the winter and prepare it for next year’s growth.

It is important to follow the product instructions and not exceed the recommended amount of fertilizer, as over-fertilizing can damage the grass. Also, it is important to make sure the grass is moist before applying fertilizer and to avoid applying fertilizer on very hot days or when heavy rain is expected.

Here are some tips for fertilizing your grass effectively:

  • Use a high-quality fertilizer that is designed for the type of grass you have. Be sure to follow the directions on the product and do not exceed the recommended amount.
  • Apply fertilizer when the grass is wet. This will help the fertilizer adhere better to the grass blades and be absorbed more efficiently.
  • Avoid applying fertilizer on very hot days or when heavy rain is expected. This can cause the fertilizer to wash off and not be as effective.
  • Water the grass after applying fertilizer. This will help the fertilizer activate and spread more evenly.
  • Do not cut the grass too short. Leaving a little extra height will help the grass be more disease and drought resistant.

According to the University of Illinois, nitrogen, phosphorous, and potassium are the three major nutrients that grass needs to thrive.
