Retaining wall garden boarder

I am building a double stack retaining block garden boarder. I want it high enough so the grass and garden don't mix. How far below the grass line do I need to bury my first block. Also, do i need to use that garden lining underneath and in between the blocks and the soil for the garden?

Thanks in advance for the help.

Retaining wall garden boarder

What is a double stack retaining wall?

What is the elevation distance between the grass and the garden area?

It sounds like a typical application for segmental retaining wall block (without doubling) that are available everywhere.

I have the same questions. What's a double stack retaining block? If you sink the block down halfway into the soil you shouldn't have any invasion of grass.

Instead of useing one row of retaining blocks I was going to use 2 rows, making the boarder taller (higher). The blocks are 4 in. in height, so the boarder would be 6 in. high (if i bury half of the first row of blocks). With it being this high, would i need to worry about putting a lining between the garden soil and the blocks?

It sounds to me like you are just doing an edge, not a retaining wall, but using the blocks for retaining walls. Is this the block you are using? It requires a cap as you can see in the pic.

This site shows the first block buried halfway into the soil.

Here's a simple two stone high, but it's sitting on a brick patio. It will give you an idea of what it looks like without the cap.

Edging ideas.
