1/4"- 1/32" Black Natural Cascade Mountain Volcanic Lava rock for use in soil mixes for Bonsai, Succulents, Cactus, hydroponics and soil mixes for specialty nursery plants. Also for top dressing bonsai and terrariums.
Lava is very non uniform in size. Thus all sizes are approximate. The Lava comes from the mine at 3/8 inch minus.
We then rescreen to remove Lava over ¼ inch. All lava that falls through our 1/4 inch screen and does not fall through our 1/8 inch screen is considered 1/4 inch lava even though the size is mostly under 1/4 inch.
All lava that does not fall through our 1/4 inch screen is considered 3/8- 1/4 inch lava.
If you are concerned about the size of Lava you will receive and would like to order samples so you will know exactly what you will get, you can do so for the cost of shipping. Then, if you decide to order 6 gallons or more, the freight cost of shipping the samples will be reimbursed. Just leave a message in Special Instructions to Seller at checkout when you make your larger 6 gallon or larger order and we will refund for your sample shipping costs.
*Lava is an organic material that continuously breaks down. Some fines may occur during the shipping process. Lava from different parts of the mine is slightly different from other parts of the mine, so there will be a slight variation in size with each order.

Pleasing black color. This lava is very hard. Most particles are 1/4", with a few down to 1/32". Neutral PH, doesn't rot, all natural, relatively light weight and porous. First photo shows our 1/4" - 1/32" black lava dry, the second photo shows the lava wet.
Our lava is hand packed and bagged with a reusable tie for easy storage after you have used part of the bag. If your lava dries before using, moisten it to keep dust from forming. Dust from any rock or potting soil product should not be inhaled and can be irritating for people with sensitive lungs.
Free Shipping to most locations. We cannot ship to AK, HI, APO, US Territories, or areas considered remote without a freight surcharge.
