    Could I get some opinions on the importance of Lime applications. Does it really make a big difference to keep the PH near 7 to keep the lawn Green and for maximum fertilizer absorption ?

    A pH of 6.0 - 7.5 is the optimal range for turf growth. Some researchers have indicated that there is reduced fungal activity in this range.

    When PH falls below 6 the lawn will stop taking in nutrients and will start to thin out over time as the PH continues to lower and you will start seeing more moss/fungi growth in the lawn. Lawns that see minimal direct sunlight or have numerous trees or poor drainage will be more of a candidate for lime applications than a lawn that sees direct sunlight during most of the day. It is very important to take a soil test to determine if lime is needed or use a PH meter. A test can tell you the exact PH and knowing the correct sqf will give you the correct amount of lime to put down to raise the PH up to the desired level of 6.5-7.0
