ᐅ Edging for Lawns… How to Install It Correctly?

Hello everyone,

I am planning to install lawn edging soon. I have chosen concrete lawn edging with rounded edges on both the front and back because I want to create various curves.

Now my question is: What is the best way to install the lawn edging (about 4 cm thick (1.5 inches))?

Ideally, I would like to simply place it directly into the ground without using concrete, gravel, crushed stone, or similar materials... This would have the advantage of allowing me to make changes easily and not “contaminate” the nice topsoil.

Thanks for your advice.
Good luck, Christian

We dug a trench and poured earth-moist concrete into it, then set the edges into the concrete. It holds well.
There is a YouTube video about this.

We did exactly the same, also to allow for quick changes.

And it holds?
Without gravel, sand, or crushed stone?
The concrete doesn't get contaminated either, meaning it doesn't absorb or soak up and turn brown? Even if it lies directly on the 'dirt'?

The problem will only become apparent in the future. For now, it holds, but the lawn will grow into it and lift the mowing edge.

Solution: Dig a trench slightly wider than the stones and about 10 cm (4 inches) deeper than the thickness of the stones. Fill the 10 cm (4 inches) with moist concrete, set the stones in it, and provide concrete supports on both sides. Let it cure, then fill the remaining trench with sand. The grass will no longer grow into it because of the concrete.

The concrete doesn’t get dirty, so it won’t absorb or soak up moisture and turn brown? Even if it’s placed directly on ‘dirt’?

Concrete, whether untreated or colored, always gets dirty. Pressure washing only helps temporarily. I’ve never seen grass pushed upwards; tree roots are stronger in that regard.
