I dont have a mulcher mower and if I dont bag and leave the cut grass on the
lawn , I get dead spots where the grass clippings suffocate the living grass
plants.

Is bagging the lawn when mowing simply an aesthetic point of view? I bag
each time I mow the lawn, but even with a walk behind mower 12,000 square
feet tends to make the job a lot longer bagging.

Are there disadvantages to not bagging?
