Using the correct amount of grass fertilizer is essential for a healthy lawn. Too little won’t provide sufficient nutrients, while too much can be detrimental to grass health and create environmental hazards.
Ideally, you should start with a soil test to see what’s already in your soil. This will help you to identify how much fertilizer you will need. Follow the recommendations on the soil test results, or if there isn’t one available, consult local experts for the best advice about application rates and timing.
Whether natural or synthetic, use only recommended levels of fertilizer for your particular species and mix it thoroughly into the soil evenly throughout the entire area you are treating. Additionally, make sure that fertilizer does not build up on surfaces around sensitive areas such as pavement cracks, as this can wash off into streams, potentially resulting in contamination of local waterways.
It’s also important to consider mowing height when deciding how much fertilizer to apply; generally speaking, lower mowing heights require more frequent applications of lighter amounts, while higher mowing heights mean fewer applications with higher amounts of fertilizer.
Finally, always follow instructions on the packaging and check with your local authorities before using any additional fertilizers beyond those specs given by them, as over-fertilizing may result in unwanted taxes due to government pollution regulations.
