In my years of working with people to establish quality turf and control many of its problems, I have come across many misconceptions people have about lawn establishment and control.
Misconception number 4: A yearly application of lime is necessary for a healthy lawn.
Proper soil pH is needed for turf to uptake nitrogen to maintain its vigor and greenness.
The only time lime is needed is if the soil pH is too low (generally below 5.5).
A soil test to establish the pH is needed before applying lime unnecessarily.
