Edging making beds bigger every year (lawn, landscaping, trim, cutting)

[Shet]

I have mulch bed along the fence as well as house foundation. The landscaping company does edging every week (with a string trimmer if that matters). After a couple of years, I have now noticed that the beds are becoming bigger because each time they edge a small vertical portion/slice of the soil is removed. How do I avoid this ?


For now, I am thinking of telling the landscaping company to stop edging.

I ask the landscaper (when I use one), to only trim / edge hardscapes like curbs, sidewalks, or fences - don't touch the plants.

I have fist-sized rounded river rocks placed in rows along the edges of the beds. The rows of rocks stop the trimmer from cutting into the soil on the lawn side and they prevent the mulch and soil inside the bed from spilling or washing out of the bed onto the lawn. And with the rocks there it really looks so much nicer and tidier, quite elegant actually. Bricks will work the same way too.
