Only remove one-third of the grass height when you mow to prevent damage and stress to the lawn. Taking too much off at once starves the roots and may expose new lower leaves to sunburn.

So What Is The Difference Between The Two? Trimming the Lawn makes horizontal cuts to eliminate grass and weeds in areas in which your mower can't reach or wherein it is able to injure plants. Edging makes vertical cuts that define walkways, islands, borders, and flower beds.

“Trimming” refers to cutting the turf height horizontally, just like your lawn mower does. Trimming is performed in places the mower cannot reach, like at the interior corner of a fence. The mower's turning radius will not usually allow for mowing all the way to the fence.

While there is no definitive answer, it is often found that doing the edges first can be easier and leave a cleaner appearance. Doing the edges first will mean that the excess clippings from the edges will then get cleaned up when the mower goes over the top of them, making the clean up a lot easier and quicker.
