How Often Can I Apply Sulfur to My Lawn

The lawn like all plants needs nutrients such as nitrogen, phosphorus, potassium, etc. Those are the primary nutrients. However, the lawn also needs secondary nutrients such as sulfur. The secondary nutrients are needed in smaller quantities, but they are still needed for the correct development of the lawn. So, how often can I apply sulfur to my lawn? Continue reading to know all about it.

Sulfur, in addition to allowing the correct development of the lawn, is a powerful antifungal and pesticide. Throughout this article, I will explain in detail how to apply sulfur to the lawn.

Benefits Of Using Sulfur on the Lawn

Before I answer, “How often can I apply sulfur to my lawn?” I’m going to tell you all the benefits sulfur has on lawns and plants. Applying sulfur to lawns that are patchy or brown will be beneficial to the lawn, but the effect is not immediate. To have a green lawn it is best to apply sulfur regularly over time, in the following paragraphs I will explain how often to apply sulfur to the lawn.

Sulfur serves to reduce the pH of the soil, if your soil has a high pH, sulfur will help to reduce it. Also, this effect of reducing the pH is not immediate but as mentioned above, sulfur should be applied over time. To know the pH of your soil, I recommend you to read our article about how to measure soil pH.

Here are the other benefits of sulfur in lawns:

  • The grass will withstand the winter better.
  • Sulfur is a powerful antifungal and pesticide, so the lawn will be less susceptible to diseases.

I recommend measuring the pH of the soil before applying the sulfur to check after some time if the pH has dropped a little. In this case, you will also apply sulfur to improve the growth of your lawn, to lower the pH of the soil there are other alternatives. The ideal pH for lawns is 5.5 to 7.

How To Apply Sulfur to the Lawn

How To Apply Sulfur to the Lawn? Before applying sulfur to the lawn, I recommend measuring the pH of the soil to verify the values. The lawn will grow and develop properly in soils with a pH between 5.5 and 7. You can use pH strips or an analog/digital pH tester.

Applying sulfur to the lawn is very easy, simply sprinkle the sulfur on the lawn and wait before watering the lawn. Normally you should wait 20 minutes before watering the lawn. I recommend using gloves to spread the sulfur on the lawn.

You can apply sulfur in the spring and then in the fall. Remember not to exceed 10 pounds (4.5 kg) of sulfur per 1000 square feet per year. This means you could apply 5 pounds (2.2 kg) of sulfur in the spring and 5 pounds (2.2 kg) of sulfur in the fall to the lawn.

Also, before applying sulfur to the lawn, you should consider the following:

  • Apply sulfur at temperatures below 82 °F (28 °C), since if applied at higher temperatures, the sulfur could burn the plant. It is recommended not to use it with high humidity.
  • Do not mix sulfur with oils or alkaline reaction elements. For example, if you use neem oil, you should wait 21 days to apply sulfur.
  • Sulfur should not be applied on fruit trees whose fruits are going to be preserved, nor on land where sensitive fruit trees (pear, apricot, or apple trees) have been planted.
  • It is advisable to apply sulfur on days with little wind to gain precision.

Final Conclusions

Sulfur is an excellent nutrient to apply to lawns and plants using the recommended dosage of sulfur. Too much sulfur can burn or damage the lawn. It is safe to use sulfur if the recommended dosage per 1000 square feet is followed.

I have used sulfur for many years to keep my lawn green and healthy. It would be best if did not exceed the recommended dosage of sulfur for lawns. I always use the recommended dosage and my lawn stays beautiful and perfect every year.
