New source for Akadama replacement medium.

Some of our members have been experimenting with using cat litter as a replacement for Akadama. The  information below was found on Harry Harrington’s Bonsai4Me website and seems  useful information for those heading down this road. If anyone else in the club has comments please leave them so we can continue to experiment with these mediums.

Info from bonsai4me

Akadama, Turface and Seramis are among the most popular high quality (inorganic) soil components available in which to plant your bonsai. Unfortunately, they can be difficult to source and are expensive particularly if you have many large trees to repot, have to buy by mail order or just require a small quantity for a small number of trees.

These soil components are all (basically) clay granules that have been fired/heated to create small pellets or granules that are water retentive, extremely well-draining and are stable, that is they will not breakdown over the course of the year.

Some cat litter products are exactly this; fired clay granules. Originally, a knowledgeable fellow enthusiast who has been using it as a bonsai soil for the past decade introduced me to using clay granules intended as cat litter a number of years ago. I have been planting all of my bonsai in this particular brand of cat litter for a number of years now and it has proved to be an excellent material that I would now comfortably recommend as being superior to Akadama and Seramis.

As time has gone on since first writing this article around 2004, I have since heard from many enthusiasts who have switched to Tescos Low Dust Lightweight and a number of other similar (diatomaceous earth/diatomite) products with great success.

United States brands:

1st reference:

NapaBryan Russ has been practicing bonsai for 3 years now and says he has tried many different types of American-brand cat litter’s with no luck. However, Bryan says after a lot of research into diatomaceous earth “it lead me to contact a mineral mine in Nevada and I found out that NAPA auto parts sells their freshwater diatomaceous earth as an oil absorber.  It is 100% Diatomaceous earth and is sold under the NAPA store brand name and comes in a 25 lb bags. It is around 8$ per bag and works awesome!! Make sure to get the 25 lb bag and double check the back of the bag and make sure it says diatomaceous earth in the small print.

NAPA Auto Parts stores are all over the US and anyone should be relatively close to one. Bryan goes on to say “the murky water that is left after one initially rinses the diatomaceous earth for the first time is actually a mechanical pesticide. I spray the liquid on my trees if they get aphids and the aphids are gone the next day. The sharp microscopic edges of the Diatoms cut through the exoskeleton of the insect causing them to dry out and die.”

2nd reference:

Though not diatomite exactly, another very similar product that I have heard being used in the past in the US is ‘Dri-Zit’ or ‘Hi-Dri’. Cory J. has e-mailed to say he has ‘found a very good akadama substitute in the US; it’s called Hi-dri, and you can get a 40 pound bag at Carquest Auto Parts for about 8 bucks. It’s the same thing as Dri-zit, which they unfortunately don’t make any more.’ A quick search on Google shows that a large number of enthusiasts have found this product to be a very viable soil for bonsai with the same qualities as the cat litter I am using.

Here is a link to Mr. Harrington’s website where is discusses this topic.
