String trimmers are designed to cut grass at various heights, which can lead to uneven and jagged edges along lawn borders.

Damage to Lawn Structures


The rotating string of a weed trimmer can inadvertently damage nearby structures such as fences, flower beds, and garden ornaments.

Increased Maintenance


String trimmers cut rough and unevenly. As a result, they require more frequent maintenance and leave a less polished appearance.

Risk of Injury


Using a string trimmer for edging increases the risk of accidental injury, especially when working close to hard surfaces or uneven terrain.

Strain on Equipment


Continuous use of a string trimmer for edging can strain the equipment, potentially leading to premature wear and tear.

Overgrown Borders


Edging with a string trimmer tends to leave behind overgrown borders that quickly become unsightly and difficult to maintain.



String trimmers may seem like a quick fix, but multiple passes and touch-ups are often required to edge with a string trimmer.
