Pumice - USA Bonsai, Cactus & Succulent Pumice Soil
SuperFly Bonsai's USA Sourced Pumice
Pumice is commonly used in bonsai as soil for many different types of trees. You will find pumice primarily in bonsai soil mixes as it helps dry out the mix. One of the biggest benefits of pumice is it's ability to retain some moisture while allowing air to the roots. Pumice generally will not break down over time so it can be used over and over again. This is one of the three primary ingredients in the well known "Boons Mix" (Pumice, Akadama, Lava)
Is It Dirt?
No. Bonsai trees do not like "dirt" and will in most cases die if left in dirt over long periods of time. This is substrate.
What Is In It?
Pumice is a type of Volcanic rock. Ours is mined out of California. The pumice may contain a small amount of cinder which is also a volcanic rock which is formed around pumice.
How Do I Use It?
Repot your bonsai tree in this soil if your tree likes dry conditions or mix it with other bonsai soil amendments to create your own soil. Be sure your bonsai pot has holes in the bottom covered by bonsai mesh.
Each micro climate may require different amounts of water. On very hot/dry days you may need to water two/three times while around freezing you may need to water just once per month. Push your finger 1" into the soil and feel for moisture. If it is dry, it is time to water.

I really love this small size pumice for my young, pre-bonsai trees. I have found that it improves healthy root growth. I use it with some turface and pine bark in the following ratio: P:T:PB (2:2:1).
Once the trees get to a certain size, I switch to the professional mix.
What I really like is that you can get the pumice in different particle sizes so that it fits with the size of the akadama and lava rock that I'm using.
This is great pumice, perfect size, nicley sifted. perfect for my Rocky Mountain yamadori.
Superfly does charge a very slight premium for its pumice, but its well worth it given the precision sifting and nearly complete absence of dust and uniform size.
QUESTIONS & ANSWERSAsk a Question
Is your pumice sterile ?
Fresh from the mine. Not treated in any way beyond that.
Is the 1/4" or the 5mm smaller?
The 5mm will be slightly smaller. The 1/4" are roughly 6.5mm.
how much does the 12qt weigh?
The 12 quart bag weighs 12 lbs.
Is there anything mixed in with the pumice rock? Or is it pure? I have heard that clay mixed in it can help control salt levels.
We do not mix anything into the pumice, but it is common to have granite mixed in from when it was mined. I have never heard of salt being a problem with pumice used for bonsai. At our nursery we don't really put anything in pure pumice, we mix it with akadama, lava and kiryu in no greater amounts than 1/3 of the total mix.
If you are speaking of regular clay, I would caution against this as that would defeate the purpose of using the pumice in the first place. Clay has horrible drainage in most cases. We don't generally use any organics in the soils we use in house, pure substrates.
What is the CEC of this pumice?
This exact pumice was never tested, but as with most pumice from the USA it will be around 75 meq/100g
Which is the largest diameter available of the Pumice rock
The 7mm is the largest size we sell.
