When attempting to reduce thatch in a lawn, core aeration is a much less abrasive alternative to de-thatching. The cores of soil that are overturned contain bacteria that the lawn uses to naturally eat away at thatch build-up. Green Thumb prefers to apply lime along with a core aeration in cases where thatch reduction is the objective. During these circumstances the cost of the lime is reduced.
