Applying Lime To Lawn To Raise pH – How Often To Do It?

Q: How often can one apply lime to a lawn to raise the pH?

A: You can apply lime to a lawn, if needed, a couple of times a year. Since it can take several months for lime to change soil pH, I recommend you have a soil test done every two years. Having your soil tested by a university laboratory ( is cheap and easy to accomplish. A soil test report will tell you not only the soil pH numbers but also the levels of other nutrients that might be lacking. The acidity of the soil directly affects how fertilizer is absorbed, so you don’t waste money.
