Advice as i try new soil mixtures
Hi guys,
I'm thinking of trying afew different soil mixtures for a couple of my trees.
Im looking at using only the following together;
Zeolite
Pumice
Tan bark
Can anyone advise if they have used similar components together and how successful its been?

Diatomite, Zeolite, Pumice sucessfully and others i know do the same with a bit of pine bark in too,
Now that Diatomite is no longer available, i will be using Akadama instead.

Re: Advice as i try new soil mixtures
Tan bark is probably really pine bark these days. You'll either need to find the finer grade pine bark or find a way or reducing the larger grades into smaller particles then sieving out the fines.
Pumice seems to be a popular inorganic component at the moment so must be reasonable readily available. It has good water holding ability, does not break down and is reasonably light. You'll just need to find a source of the correct sized particles.
My advice is do not get too hung up on particular products or brands. You need to understand what each component does then you can look for locally available substitutes with similar attributes. There is a lot of science behind what makes a good potting mix. If you don't properly understand all that goes into a well formulated mix I think it is probably better to purchase a mix from someone who does.

Re: Advice as i try new soil mixtures
I just got some pumice and it seems pretty good. It’s very heavy though... even my small pots now weigh a tonne. Not sure if it’s heavier than the scoria I used to use but it’s got to be close.

Re: Advice as i try new soil mixtures
I thought pumice was low density and low weight, due to the bubbles etc. when formed? Are you sure you’re using pumice - maybe perlite? I know you can get perlite both expanded and unexpanded, but don’t think the same can be said for pumice. I could be wrong but just wanted to clarify.Beano wrote:I just got some pumice and it seems pretty good. It’s very heavy though... even my small pots now weigh a tonne.

Re: Advice as i try new soil mixtures
That’s what the sack said. I’ve gotten it from two sources and it’s the same.
I’ve tried perlite for a year and I don’t really like it. It is very light. It’s almost like putting bean bag filling in your mix.

Re: Advice as i try new soil mixtures
I'm guessing Beano is using the same pumice as I am, and it's quite heavy. Pumice can originate from any magma during an explosive eruption, so the weight and porosity can vary. This stuff certainly won't float, but my pines love it!
Cheers,
Matt.
Keels, I've used all those materials together with success so I don't see any problems. There are as many soils recipes as there are bonsai enthusiasts but a good rule of thumb is 2 thirds inorganic (pumice, zeolite, diatomite, akadama etc.) to 1 third organic (pine bark, potting mix, coir, neem etc.). Closer to 50/50 for deciduous and tweak according to your climate and species.Can anyone advise if they have used similar components together and how successful its been?
Cheers,
Matt.

Re: Advice as i try new soil mixtures
Thanks for the replies Beano / Matt S, happy to stand corrected - I just never had heard of pumice with a weight equivalent(ish) to something like scoria.
I also wondered if maybe it was unexpanded perlite as I have substituted this into my mix this year in place of diatomite due to the quality issues ... I was kinda hoping for a bit of feedback on how it goes!

Re: Advice as i try new soil mixtures
Where do you get your German peat from Mike ? I got some from Taiwan but I am not so sure of it's authenticity
On a serious note no one here has mentioned to do some trials first. Do NOT put your best tree into a mix that work for some one else in a different micro climate. Always try a new mix with a tree you can afford to lose.

Re: Advice as i try new soil mixtures
Here’s my mix Keels :
50% unexpanded perlite (was diatomite... but that went south, so I adapted)
30% pine bark
10% zeolite
10% coir peat
I noticed Mike left zeolite out of his extensive ingredients , maybe just an oversight - I like it in my mix (although he does have Gromium which I have had trouble sourcing... lucky bugger!)
This mix served me pretty well last year (remember though it was diatomite then... not now). My aim is to keep it simple and use the same mix universally for all my trees. Pines, deciduous, natives...all of em! I hope the perlite works - I feel good about it... no choice but to change given the diatomite quality issue.
I will say I had pines in essentially a pine/coarse sand mix also and they were happy. You can make this as easy or as complex as you like I guess! Good luck with whatever you do.
