I bought the Supreme Garden Mix from Adobe Rock earlier this spring (2026). Their website says it works for potting plants and planters, so I used it in larger containers (around 18-gallon size) that I need to be able to move.The mix is far too heavy for that. It is mostly topsoil and lava fines, with maybe some perlite, and it does not match the composition they advertise (30% Adobe Mulch, 22% topsoil, 20% coconut coir, 18% lava fines, and 10% perlite). When I work through it I see very little coconut coir or mulch, and there is essentially no manure in it to help with plant nutrition—maybe a little from the Adobe mulch, but nothing like a proper potting mix. Their stated percentages need real quality control.An 18-gallon planter filled with this is hard for me to move, and even my husband finds it difficult. I have been a serious rose gardener for several years. I regularly move pots, swap plants, and shift roses between containers, so I know the difference between a workable mix and one that is too heavy. For years I used Miracle-Gro and similar name-brand mixes from Home Depot in the same size pots and could move them easily. Working with this super-heavy mix strained my wrist badly enough that I needed a small surgery.I contacted Adobe Rock multiple times about the weight, the mismatched percentages, and the lack of usable organic matter. The website still has not been corrected. What is especially frustrating is that the workers there just will not take you seriously or respect the knowledge of an experienced gardener. What was funny (and telling) is that when I raised the issues, they asked a local gardening YouTuber to “teach” me about soil. It was completely off-topic, and the information the YouTuber shared was something I already knew. The solutions they offered were to drive the super-heavy soil back to their yard and pick up other soil to mix myself. That was not practical—I do not have the time, and I would have had to get my car dirty again. In the end I went to Home Depot, bought more soil, and fixed the problem myself.I am writing this review because the workers simply refuse to take customers seriously when real problems are raised. Adobe Rock claims everyone likes this mix (and apparently everything they sell). After this experience I now even doubt the other product reviews here, because the pattern is that they claim everyone is happy with everything. I am here to tell you and warn you that this is not a good soil for potting plants or movable planters. The advertised recipe does not match what is delivered, the product is excessively heavy, and the response to legitimate concerns was dismissive.

Such well nourished soil

Seemed like a nice clean mixture of organics and soil. We will see how things grow—then we will know!
