"Upon finding that I work as a professional bonsai artist, many people will remark that they once had a bonsai, but it died and with some regret, they gave up".
Based on the Bonsai Basics section of the hugely successful Bonsai4me.com website and an e-book of the same name, 'Bonsai Basics: The Foundations of Bonsai', written and developed over the past 15 years is out now!

UPDATE MARCH 2016: Tescos stores have re-branded 'Low Dust Lightweight Catlitter' which is still available but in new packaging.
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 had already been using it as a bonsai soil for a 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 catlitter 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.
(Pre-March 2016) Tescos Cat litter with its yellow packaging
available in the UK, I use an own-brand product available from
'Tescos' called 'Low
Dust Lightweight Catlitter'. There are other brands
that make suitable bonsai soil (see the updates at the foot of
the page) but this is the only one I have direct experience of
and can therefore personally recommend.
I use this product for my all of my bonsai, with cuttings and air layers and even newly collected yamadori (collected trees) all to good effect.
UPDATE MARCH 2016: Tescos stores have re-branded 'Low Dust Lightweight Catlitter' which is still available but in this new packaging.
Tescos have confirmed that this is indeed the same product but in new packaging.
Tescos Catlitter as bonsai soil
At a cost of just around £5.00 for 16 litres, easy availability (as there seems to be a Tescos Superstore wherever you turn in the UK), and an absolutely ideal medium for growing healthy bonsai.
On the left is Tescos 'Low Dust Lightweight' Catlitter, on the right, chopped bark. My personal favourite bonsai soil is the combination of the two ingredients in the centre of the image.
'Low Dust Lightweight' can be used on its own (100% pure) for all tree species. If you require a more water retentive mix for bonsai in small pots (mame) or to lengthen the amount of time between each watering, the addition of approximately 10%-20% chopped bark is useful.
At present I am adding approximately 20%-25% bark to my basic catlitter soil mix.
