Does lime green grass?

Adding lime to soil raises the pH so it becomes less acidic. Lime can 'green-up' a lawn. The best way to determine whether or not your soil needs liming is to test its pH. The target pH level of turf grass, for example, is between 6.2 and 6.5, so if your soil has a lower pH it will likely benefit from adding it.
