Replace Rocks with Trench Edging for Mulch Bed Borders

What happens here

The video advises against using rocks as a border around mulch beds, especially near turf, because grass will inevitably creep between and over the rocks, establishing itself within the mulch. Instead, implement trench edging. This involves digging a shallow, V-shaped trench or a clean, sharp edge around the perimeter of the mulch bed, acting as a physical barrier that grass roots struggle to cross. This method provides a much cleaner and more effective separation between the lawn and the mulched area.

Goal: Prevent grass encroachment into mulched areas.
