Black Horticultural Lava Rock Soil Additive for Cacti Succulents Plants No Dyes or Chemicals 100% Pure Volcanic Rock 2.2LB Top Dressing

Good value for money and quality products

This stuff not only breaks up your soil for better drainage but looks awesome as well. Practical and a great decoration, need to buy more.

Expensive for what it is and it is not really black - turns black when wet - otherwise I would say it is more grey than black.

Have used it as a base layer in terrariums and mixed in soil. Looks good is light weight and absorbs water nicely

Need to use in an indoor pot. Looks very nice and decorative. Happy with purchase

I use this product to put around my indoor plant. as grow them and give away to friends and family.

not what was described I brought 3 ITEMS of stones from seller all different colours, also I took a pic of the black stones that are not black as shown in the picture they are a mix of browns and reds and even green, i put the bag with the Red Horticultural Lava Rock next to it and the shadow makes it look darker but as you can see in the next picture with natural light these are not black and i need the black ones please get in touch so i can get this sorted thanks

Fine and as expected just very very dusty so watch out

worked great for my aloe plants. It's a small bag. Enough to mix into my potting soil and cover the top of two 5" pots

Schöne Deko Lavasteine

This lava rock is perfect for my succulents and hoya plants! The pieces are a great size — not too big or dusty — and it’s 100% natural with no weird dyes or residue. It mixes really well with potting soil or coco coir to improve drainage. I also use it as a top dressing, and it makes my pots look super clean and professional. It’s nice knowing it’s pure volcanic rock, not synthetic. Definitely worth buying again!

Einzelnen Steine sind deutlich kleiner als erwartet

I’ve been shopping around for a succulent/cacti gritty mix for quite some time now and couldn’t be happier that I decided to purchase this lava rock and make my own! Out of all the different top dressings and mineral amendments I use for my succulent collection, this is by far my favorite. Particularly for smaller succulents with extremely low water needs (such as Lithops, pictured with the lava rocks) I enjoyed using this as an attractive and quick draining substrate. For anyone else looking for unique substrate for their succulents, I’d definitely reccomend using this as a mix-in (although it could get a bit pricey for larger plants/pots) or as a top layer to contrast with smooth/rounded plants.
