Grass Fertilizer Mix Ratio: 10 Essential Facts You Need to Know

Nitrogen (N), Phosphorus (P), and Potassium (K) Ratio

The most important factor to consider when choosing a grass fertilizer is the NPK ratio. This ratio represents the percentage of nitrogen, phosphorus, and potassium in the fertilizer. The ideal NPK ratio for grass is 3-1-2. This means that for every 3 pounds of nitrogen, there should be 1 pound of phosphorus and 2 pounds of potassium.

Nitrogen Application Rates

The amount of nitrogen you apply to your lawn will depend on the type of grass you have and the time of year. Cool-season grasses, such as Kentucky bluegrass and fescue, require less nitrogen than warm-season grasses, such as Bermuda grass and zoysia grass. The best time to apply nitrogen to your lawn is in the spring and fall when the grass is actively growing.

Phosphorus and Potassium Application Rates

Phosphorus and potassium are essential nutrients for grass growth, but they are not needed in as much as nitrogen. The general rule of thumb is to apply 1 pound of phosphorus and 1 pound of potassium per 1,000 square feet of lawn.

How to Mix Grass Fertilizer

Once you have chosen a grass fertilizer and determined the application rates, you can mix the fertilizer according to the manufacturer's instructions. Most grass fertilizers are mixed with water and applied to the lawn using a spreader.

Safety Precautions

When mixing and applying grass fertilizer, it is important to follow the safety precautions on the product label. Wear gloves, a mask, and eye protection. Avoid contact with the skin and eyes. Do not breathe the dust.
