Hi,
Though our townhome community’s lawn indicates soil tests with good Ph, Tru green says U of M recommends adding lime anyway. If so, why is it recommended?
Thank you.

You don't mention what the 'good pH' reading was, and whether the soil analysis was done in a laboratory.
For turf-type fescue a pH of 6 is ideal, and we'd consider a lime application if it were lower than about 5.5.
We assume that you (and Tru Green) are aware of the lawn regulations that are in place regarding pesticide use for many if not most of Montgomery County, which would preclude some of the actions this company regularly takes.
Maryland also has a Lawn Fertilizer Law.
