I have been the care giver of the best lawns around, however, these are my opinions. I believe that bagging the lawn is a matter of preference. Bagging offers a more beautiful end result, however the draw backs are that its more labor intensive, takes more time, and if the lawn waste is not recycled then it goes right into the landfill.
Some experts believe that bagging is a must as it helps reduce thatch, while others will tell you that mulching the clippings back into the turf adds a natural source of nitrogen and fertilizer. Again, I believe it comes down to preference. While I was in the business, I had some customers that required the lawn be bagged each week, those jobs usually took twice the time and labor to complete verses the lawn I mowed where we discharged the clippings, and mulched them up.
I can honestly say that in 15 years mowing lawns that I noticed a difference in the health of the lawns that we bagged vs the ones that we did not bag. However, the bagged lawns always looked noticeable more manicured, and the striping is more defined, leaving a more crisp appearance.
So if you are a do it yourselfer it comes down to is it worth the extra back breaking work for you to bag the clippings and dispose of them each week to attain the better looking result… well that’s up for you to decide.
