It's more beautiful in person.
I put this around all of the cacti in my garden (that are sitting in pots) and everyone who sees it loves the little gritty gravel that's multicolored.It helps to keep weeds & bugs out of my pots too.

Comes with a lot of gravel for the amount you pay. Does have quite a bit of dust so I'd recommend rinsing it off in a strainer before use if you get easily irritated. Nice variety of colors and sizes of stones and very good quality as well. Can be used in place of something like perlite to add drainage and aretion to soil or used on its own so it's very versatile and a great purchase for plant lovers.

I use this for mammalaria, lophs, and several other my cacti. It has zero sand in it which is alot neater than a sandy mix. This has zeolite, maifatanum, pumice and I believe one or two others I can't recall. These are all mineral rocks but on it so won't settle. Fast drain! Aesthetically appealing!

For small lophs and other slow growing, very small root structures, to I add a bit of bone meal and earthworm castings in there to provide more of an amalgamation for mini-roots.
I would have given it a five because it's also very clean but the small bag is about 1 1/2 cactis worth. I mixed it with more pumice to and some 1/16" akadama. Good product!

I bought the 2 1/2 lb, 1 quart bag of mixed color to plant lithops. It came quickly and was nicely packaged. I saw people complaining about the amount received, so I measured it out. It is advertised as 1 quart, which equals 4 cups. There were actually a full 5 cups of mixture in the bag, so I got more than was advertised.
This "mixed colors" option does not need to be washed. It specifically states, "Bonsai Succulent and Cactus Soil Boniosz Gritty Mix Rocks." There is soil mixed in with the rocks to make it a complete mix. It comes with the necessary soil and rocks needed to grow lithops and succulents. You don't need to add anything to it as long as you don't, for some strange reason, wash away the soil portion of the mix. Each color option is different. Some are fillers and some are for top dressing the soil. Mixed colors includes soil as a growing medium.
I'll definitely buy this mix again.

I love how this bonsai mix of beautiful colored lightweight stones complements a wide variety of plants. It looks gorgeous next to so many colors and makes them pop! It is lightweight and airy so it does not hold moisture into the soil. I love placing it under the edges of the agave pups to protect them from wet soil, which can cause rot. It is a beautiful amendment for cactus, euphorbia, agave, aloe, or just about any succulent. I love that the tiny stones are lightweight enough that the pups can still work their way up through the soil and it is not too heavy to stop them from emerging.

When I first opened the bag, I didn't notice any type of smell, and I was able to use it right out of the bag without feeling the need to wash it. As I got almost to the bottom of the bag, I did notice that there was quite a bit of dust that had settled to the bottom, so I dumped it into a wire strainer and rinsed it in the sink. It was only about the bottom 2 inches of the bag that seemed to be dusty, not the whole thing, and not enough to stop me from buying it again. I loved it so much, I bought a second bag!

These are the soil amendments I would choose separately all in one at a good price . Work wonderful with my hawothias and cactus, sometimes I add a small amount of potting mix or chunky coco coir , depending on how dry your plants like it. I was a chronic over- waterer and lost a lot of very pretty succulents before I got the hang of the gritty mix. The diamotide is great if you have issues with fungus gnats, I usually add D. E. powder to help but this mix has it all and is a lot cheaper than akadama. Always use pots with drainage holes no matter what you plant them in, even if it's just rocky mixes like these - if you have succulents or cacti. The water should be able to run out , and you can sit them in trays to water from the bottom to form strong roots . You can add bark fines or chunky coir to pull the water up and through the roots. Really a very helpful mix !!
