Time For Lime

                                        Soil pH is a number that indicates the acidity of the soil. The term "pH adjustment" means changing the acidity of the soil by adding lime. A soil pH of 7.0 is a "neutral" pH. When the soil pH is near 7.0 or slightly less, plant nutrients are most available for root uptake. When the soil  pH is very high or low, essential plant nutrients such as phosphorus and iron are tied up in the soil and not available for root uptake. In this case the lawn will perform poorly.
                                        Often turf grasses will not show visual symptoms, but the lawn may not respond well to fertilization if pH is not in the desirable range. Disease symptoms on turf may be more severe. 
                                         Soils have a certain pH range because of their parent material, the effects of climate, and many other factors. Soils in sandstone areas may have a lower pH range. The surface soil may have a neutral or slightly acid pH and be favorable for the growth of most plants, but during construction, soils close to bedrock are often brought to the surface and spread over the lawn. This soil may have a different pH and be unfavorable for turf growth. The lawn or ornamental plants growing in the new soil may benefit from pH adjustment. 
                                         Apply ground limestone to lawns to raise soil pH. These materials can be spread with a rotary lawn spreader when they are available in pellet form.
