I have been upgrading the yard and we are doing a border around our fence and going to install plants and gravel, just curious if these pavers need sand and compaction, the ground is not entirely level, it was raw desert a few months back, how bad will it look in the future without it? We had gotten the rougher stone because we knew it was not going to be perfectly level so figured it would look better with the rougher edges? Are there any issues I should think about? Thanks for the input
