With some trees, the seeds from the tree get embedded into the soil in the lawn’s turf. This stops lawn production and lawn growth and could create weeds. A dethatcher lifts those seeds from the lawn’s turf and lifts other tree debris along with other plant materials and dead grass that can get trapped in the lawn’s turf.
In some cases aerate the lawn first. This causes thatch materials to rise to the lawn’s surface over time, then thatcher materials are easier to remove…doing this along with regular raking up of tree debris.
