Locking concrete blocks
I recommend using interlocking concrete landscaping blocks to build garden beds.
Landscaping is easy with locking concrete blocks. They have a lip on the back so they interlock.
No mortar - rearrange them as you change your mind.
Build up to a metre high. Just lay on a good bed of levelled gravel - still no mortar.
They come in numerous sizes and colours. I use two sizes of a natural cement grey.
Tight curves are easy.
Build to any radius
Pretty good results are possible for a non-professional.
Learnings
- getting the initial base level is the key to success
- make sure you have sufficient dug-out clearance behind them to allow for the batter (slope) as they rise in levels
- whack the artifical lookinmg bits off the supposedly rough corners before you stack them
- cut them with an angle grinder or masonry saw - very hard to scribe and split them cleanly like a paver or brick
- don't forget to put conduit for water and electrical in
- order more
