Creating Healthy Soil

Balancing Your Lawn’s pH

No matter how actively you care for your lawn, it all comes down to healthy soil at the end of the day. If your soil can’t provide a habitable, healthy environment for grass plants, then your lawn will ultimately suffer. 

While there are many factors to consider when thinking about your soil, but your lawn’s pH level should always be on your radar. If you have thin, discolored turf that does not grow very well, unbalanced pH may be at play. 

Your Soil’s pH

A soil’s pH level is a measure of its acidity or alkalinity, and plays a significant role in determining the overall health of your lawn. The ideal pH range is between 6.0 and 7.0 – anything higher or lower may result in unsightly, slow-growing turf. 

Your lawn is considered acidic when the pH of the soil falls below 6.0, at which point root development slows or even stops. As a result, grass plants cannot absorb the proper amount of water and nutrients. Not to worry – an application of agricultural lime (ground limestone) will give your lawn the boost that it needs to regain an ideal pH level. 

When the pH level is above 7.0, on the other hand, the soil is considered alkaline and will generally showcase a poor structure and a low capacity for water penetration. In such instances, a sulfur application may prove to be an effective remedy.  

Why Your Lawn’s pH is Unbalanced

Your soil’s pH is naturally determined by your geographic region. While some areas across the United States have a strong tendency for acidic soils, other regions encounter soils that are too alkaline. Soils generally become acidic when they lack vital nutrients such as calcium, magnesium and potassium. This exists in lawns where there has been heavy rainfall and poor drainage. Conversely, areas with dry climates and an excess of soluble salts tend to have alkaline soil.


Fall is one of the most favorable times of year to consider balancing your lawn’s pH. Your local Weed Man can educate you on the natural acidity or alkalinity of your lawn, and apply a treatment of either lime or sulfur to correct any imbalances. Because soil types and their makeups can vary greatly, the amount of material needed will be dependent on your specific lawn. Over-application of either treatment can have damaging results, as the pH level may shift drastically in the other direction. Weed Man’s knowledgeable technicians will ensure that the correct amount of product is applied to your lawn at the right time of year.
