Implement Trench Edging for Defined Borders

What happens here

Avoid using simple stone borders or similar shallow barriers around your mulch beds. These methods are ineffective because grass will inevitably creep in between the stones or over the shallow barrier, establishing itself within the mulch bed. Instead, create a clean, durable border using 'trench edging'. This involves cutting a deep, V-shaped trench around the perimeter of the mulch bed, physically separating the lawn from the mulched area. This deep trench acts as an effective barrier to prevent grass runners from encroaching into the bed.

Goal: Create a clear, effective, and aesthetically pleasing separation between lawn and mulch bed.
