What is The Best Bonsai Substrate? (Understand bonsai substrate)

[@Darkfire1300]

May your trees stay healthy and stay firmly bent or straight May free drainage and nutrition be supplied by your substrate May your plants survive summer heat and winter cold May your designs, chops and wiring, and desires be bold May your tools stay sharp and shiny bright May your yamadori be easily dug and for transport quite light May your dream greenhouse or cold frame or bonsai stands miraculously appear May we all share green thumbs, prosperity, great health and share our good cheer! Whichever year you are celebrating, may be it a Happy New Year!

This is it, the holy grail of bonsai substrate videos. This is the information I've been scouring the internet for. THIS is what beginners need to know in order to keep their first few plants healthy while they learn more specifics. THIS is the 'How to make scrambled eggs' video amongst all the videos about how to prepare a five course meal with a fancy dessert. My sincere gratitude Jelle.

Another straight forward, and simply explained Bonsai video on soil for our trees. Many times I have seen or heard you HAVE to use this ingredient or that if you do not use ingredient A, B, or C from one or more general world regions - you are not a true bonsai enthusiast. You have broken it down to which ingredients serve you best. Thank you.

[@GrowingBonsai]

Hey Jeff, appreciate the comment. And I agree. There seems to be this idea that if it is not Japanese, it is not the right stuff to use. I try to bring things down to the basic 95% needed to get good results. The last 5% tuning is for most of us out of our reach anyway, so the small difference some components *might* make, does not seem to matter to me.

[@howardmckeown7187]

[@GrowingBonsai]

:) I think the thing you will learn over time that there are few hard truths when it comes to growing bonsai. Many things work in several ways and are also dependent on local conditions & personal care possibilities / plant species. This means you can get different, yet all correct, replies to the same questions. Slightly annoying!

Here in Brazil, this discussion about the substrate is endless because we have a tropical and subtropical climate for most of the year. And also the sudden variations a few hundred kilometers should be considered, after all we are a tropical country. The "caqueira" is a genuinely Brazilian substrate that surprises the entire world bonsai community.

[@GrowingBonsai]

Yeah, I think the discussions are endless, everywhere. Even if you show people trees grown without akadama that are healthy, develop well and have good roots.. People will argue that you need to use it. Caqueira..? Never seen it I think!

Great job showing the importance and benefits of recycling substrate! 👍 If a trees dies I always throw out the soil it was in… just in case. Always interesting to see what substrates people use.. it changes from country to country depending on what you can source locally and affordably too. Cheers! 🐦💙

[@GrowingBonsai]

Hey Jay, thanks for chipping in! How are things?

[@KurisuBonsai]

Great explanation and hard work sieving! I'm using Akadama and pumice here in UK but I do have small trees! I currently make individual mixes in a bowl to what I want for the particular tree, using small scoops of the individual components, then blending till it looks right. More pumice for pines, less for deciduous etc. I've also been adding in a bit of ericaceous soil to acid loving trees for a bit more water holding and organic content. All that said, I've bought a box of premixed small grain soil from Kaizen and intend to give that a go when spring comes, looks great in the box and is working nicely in an indoor planting test so maybe I won't need any akadama this year!

[@GrowingBonsai]

I am so happy to see that more and more people realize that substrate has perhaps been made more mysterious than it need to be!

[@KurisuBonsai]

@@GrowingBonsai I follow a lot of Japanese channels and I think Akadama is about £7 a bag there so makes sense why it's used more as it is very good. Ease of repotting is another reason to choose a more grainy mix that's not often mentioned. I also see they use a thin base later of large grains then refill with their general soil to ensure good drainage.

[@XaviersBonsaiRetreat]

Definitely worth waiting for Jelle. I agree about mixing ratios - it gets harder once you start re-using soils. Availibility and price also plays a factor in my soil mixes some years. It was only last year that I was able to source the smaller pine bark so that now goes into the mix. I mixed up 80 litres a few weeks ago and I already know I will need a lot more than that - I hate sifting so much !!! Cheers, Xav

[@GrowingBonsai]

[@TheBonsaiZone]

@@GrowingBonsai I'm using 1/2 perlite and 1/2 clay particles (SafetySorb) with a bit of bark thrown in. It seems to work well and I can get all the ingredients locally and cheaply. One this I find about used soil is that the pores of the particles can get clogged up with algae and organic particles. They loose their effectiveness at absorbing moisture and holding fertilizer.

[@iamshredder3587]

Good video. You actually explained the process of akadama quite well... so many teaching it seem to not understand it properly much at all so that was nice. I wonder, have you used or even heard of "aerostones" for bonsai. ? Its basically a engineered substrate marketed as a (superior) alternative to pumice that ive been using few years now. I believe its made from perlite (the natural ore not the finished light fluffy gardening product... but the ore of it.) from turkey that fired at hi temp and other processes and produces a sterile neutral substrate that retains its minerals and holds them well and water and drains great, looks cool too imho... some bits being white like perlite and others clear like glass or crystal. But anyway without ranting too much the more i use it the more i seem to like it tbh. And its very consistent and reliabke unlike lot of pumice here (and akadama etc) . Its hard though and heavier than perlite so deosnt blow away or anything and reasonably priced too. Just not sure why i rarely see anyone else using it ir even heard of it?

[@GrowingBonsai]

I have never heard of it. So that is why I do not use it. Not something I come across here.

[@johnholloway691]

Jelle - Coincidentally, I also recycle substrate, much like your do, even with what appear to be the same Japanese (?) sieves. I mixed the leftover fines into our garden soil until I discovered birds like to dust-bathe in it in the summer, so I now just leave it in a pile for them. Waste nothing, right? Thanks for another informative video!

I'd like to propose another category. pH The substrate has strong influence on pH, and some plants prefer more acidic soils.

[@KurisuBonsai]

I add small amounts of ericaceous soil to the mix for trees like this. Azelias mostly but also used in higher quantities when making forests too.

[@GrowingBonsai]

Hi, thx for the comment. I am personally not so concerned with soil PH, but then again, I do not have many azaleas. Pretty much most species prefer a slightly acidic substrate afaik.

For the last couple of years I’m using a mix of zeolite and pinebark. Not bad so far.

Sounds like a winner. Do you have a reliable source for Zeolite? I have used pumice/zeolite mix once which was sold locally but am not sure I saw any differences.

[@snoekhoek]

@@GrowingBonsai I haven’t used pumice, so I don’t know. But the zeolite doesn’t deteriorate as far as I can tell. But for sure it’s in no way as dusty as your mix! :-)

[@FrostBiteBonsai]

This is a great video! I don't have these available locally. I will have to order. I need something that doesn't dry out so quickly indoors. So far the cactus and succulent mix, sometimes with extra perlite added, seems to work best.

[@GrowingBonsai]

Yes! I have been using cactus-mix grit as well at somepoint, untill I found a better source for pumice.

[@mm6918]

Thanks for this video Jelle! I think I'll try adding shale based on what you said because lava is really expensive where I'm at. Most of my trees are really early in development and I want to facilitate more growth. Sounds like I should use medium to large soil particles. How many mm should my medium and large soil particle be? Thanks again!

[@GrowingBonsai]

Look in hardware stores for the shale. The stuff I use is sold to be used under floors (!). I find everything over 10 mm is too big to be usefull. I use the standard japanese sieves, to be honest, I would have to measure what size mesh it has!

[@mm6918]

Thanks Jelle and Happy New Year!

[@bonsaitherapy1468]

I reuse mine. No akadama at all. Mostly lava rock, perlite, regular garden soil and sandy grit. Summer is really hot and humid in New Jersey and cold in the winter. My trees are doing well with the coarse and organic mix...lol, and I also don't really care about percentages.

[@GrowingBonsai]

In the end, it is about what works!

[@joeydupre6153]

Here in South Louisiana, U.S., our summers run in the mid 90's F for months. We need organics in our soil. I have been using about 50/50 pine bark and diatomaceous earth for 8 years. Conifers get a higher percentage of D.E. At present, I have about 25 different species and cultivars and haven't found anything that won't grow well in this mix.

Agreed! The hotter and drier, the more organics.

I think that the Japanese use their local soil so we should be able to as well. however volcanic soils are so good for bonsai, but there are artificial ones available like you mentioned. After doing many experiments, I also broke my soil down into 3 groups, with a choice of components within those groups. Reusing the substrate also works well fo me too... although I quite like this job compared to dealing with pests and diseases.

[@GrowingBonsai]

You touched upon my core thinking initially: So coincidental that Bonsai was developed specifically in the country where Akadama is abundent :)

[@KidMangaX]

Try doing that in a place with very poor soil quality, such as solid clay-- you will be very sad. Poor drainage and oxygenation.

Thanks for the video. Very educative. Didnt think about the solarization process. Quite known in the agricultural area. Was curious, about a good replacement for akadama, but you kinda anwsered it. Thanks!

[@mariob.3232]

I also have a comment though. I read that coir and pine bark overtime makes your soil more acidic. So it should be a good substrate for azaleas. Since you make a big mixture of components, most likely doesnt make big difference.

[@GrowingBonsai]

Great to hear! I am not sure how acidic it makes the substrate tbh. In general most plants prefer slightly (!) acidic over slightly alkaline soil I think to know. And yeah, Azaleas are a measure more outspoken on this!

Hey David, I think all has been answered.. I have opted for an open light substrate that drains extremely well. In summer I water twice a day, with on the hottest day an automated irrigation spray midday. The coco stays wet A LOT longer than pine bark and is therefor good for drier climates I would say.

Also did you see Appalachian Bonsai, they have a video covering this as well, testing different organic and inorganic substrates.

Hi Markus, I had been using diatomous earth pure and it stayed too wet and I got algea building on the surface, which is why I mix it with the drier vulcanics. But yeah, diatomous earth has been my go-to for over a decade. I am using a mask when working with that stuff! Check the end of the video

[@dkstott29]

My basic response is that beginners with only a few tree's should migrate towards commercially available bonsai mixes. A lot of the suggested individual substrates tend to be expensive to obtain. Perhaps when they have some knowledge, they can work on making their own mixtures.

[@GrowingBonsai]

Probably location is important here. All these ingredient are dirt cheap -pun intended- here. My mix is less than half of the cost of commercial blends. But cost should not be the main concern. If you only have a handfull of trees, there is no sense in making your own mix as you would have substrate for a decade sitting there.

In dry, hot, windy climates often an higher percentage organics, such as cocos fibre or even sphagnum moss is used in the substrate. However, I would consider looking into shade netting and a wind-break to help a litlle. And of course.. Select species that do well in your climate, thyme, pines, junipers.

[@gronkotter]

@@GrowingBonsai Thanks! I did not know thyme could make nice bonsai. I mainly have figs, jades and Australian natives because they are tough.

[@GrowingBonsai]

@@gronkotter so, in Australia? I hear trident maples do well too there.

[@jeremyhewitt7840]

As a complete beginner... can i ask....all the substrates don't provide nutrients ...so this omes just from liquid feeds, i guess ?? Am i right?🤔

[@vallvds]

Hi Jelle, what is your take on Seramis clay?

[@GrowingBonsai]

I have been adding it to my most recent substrate blend as a replacement of diatomous earth, as this was hard to get for a bit. Works well in my opinion. I do hope to be prooven wrong some day but I am really wondering to what extent substrate components matter.

[@hanskleinjan]

Try stack seeving. It saves you a lot of energy 😇😎👌🏻🌹.

[@GrowingBonsai]

Thanks for the tip!

[@guybrusselaers3917]

I wonder if you buy the clayballs“seramis” crushed of you crushe them yourself or you use them as they are? For the rest: thumbs up!!

[@GrowingBonsai]

The seramis comes as 2-4mm gravel!

[@mehranashkanian2747]

Hi. We have something like black sand . Think it's very small Granite granules It's black. It it for aeration or does it have any neutrintional value? Can you pls tell me if I need to use it in the mix or not necessary?

[@GrowingBonsai]

I would see this really just as a pot filler without any beneficial qualities, except for weighing the pot down.

[@kestane123chesmo]

does the clay group provide any nutrients at all ? if not, why not use more vokcanics, like pumice

[@GrowingBonsai]

Not nutrients in itself. But clays are really good at temporarely binding nutrients

[@dirtysouthhc2936]

How do you feel about spag Pete in lieu of Coco hair?

[@GrowingBonsai]

spaghnum? Hard to source here. ALso big. And dangerous to your lungs.

Happy new year! May all your trees grow strongly, and develop fat trunklines in 2023!

Thank You.

You're welcome

My soul mix is mola clay ,pumice ,perlite, lava rock and pine bark ...

[@GrowingBonsai]

Sounds very similar!

[@fortyoddyears5295]

Perfect. Gotta find diatomaceous earth in pellets instead of powder now and no idea where to get volcanic pellets…..pet store?

[@GrowingBonsai]

Hm.. garden centre? Hardware store?

[@daniel_do]

If I were to buy 1 from every 3 categories what ratios should I use?

[@GrowingBonsai]

I just dump them 1:1:1 together, typically. I always have some unmixed components to adjust substrate if I think it needs it but.. To me.. Substrate is made overly complex by many..

[@Riverangler78]

Dag Jelle..ik zoek mij scheel naar fijn dennen schors. Weet jij waar ik dit kan bestellen of krijgen?

[@GrowingBonsai]

Dit haal ik n de bouwmarkt bij ons, en find ik prettig spul: www.amazon.de/Bodengold-PINIEN-DEKOR-Pinienrinde-Rindenmulch/dp/B087QLB1NM/

[@fs6230]

Zur Info, in Deutschland kannst du Seramis auch direkt mit Lava kaufen ;-) Grüße

[@GrowingBonsai]

Danke. Ich verwende aber kein lava im mischung

[@JesusChrist4ever]

U forgot to mention how akadama is the best to produce ramification it definitely does have its pros n cons

[@GrowingBonsai]

For sure did not forget it.

[@JodyGrogu]

Hoi Jelle, gelukkig en gezond 2023. Ik ga dit jaar mijn boompjes in substraat planten zonder akadama, ik ben benieuwd of ik verschil merk.

[@scheers100]

Zelf gebruik ik akadama (rond 50 procent)enkel nog voor mijn tropische planten/boompjes die binnenshuis komen in de winter. En meestal ook in kleine potten staan.Voor mijn buiten planten ga ik voorlopig voor lava steen, vulkaan steen,perlite en gewone potgrond(in ongeveer 30/30/30/10 verhouding). Voorlopig tevreden van, maar waarschijnlijk nog veel verbetering mogelijk. Veel succes met jou zoektocht naar jou ideale substraat!

[@GrowingBonsai]

Beste wensen! Laat je weten hoe het gaat?

[@jaguardelcielo]

Nice!

[@GrowingBonsai]

Thanks!

[@r_man-o5o]

sir, why isn't cow dung not used in bonsai, although it seems like a good and easily available

[@moot8107]

Where is the sifter from?

[@GrowingBonsai]

One of the best known online multinational stores :)

[@smack09]

Back breaking work sifting through all the grades.. Seeing all the dust and super fines fall through the big grader thinkin, Ill be sifting through you another 3-4 times..

[@GrowingBonsai]

Yeah, I have been thinking a lot how to do this better but.. none found.

[@dimuthuharshana9602]

❤️❤️

[@GrowingBonsai]

thx!

[@abydosianchulac2]

Excellent! I'd been convinced you'd mentioned substrate components before but could never find it. Terrific overview here. One question I have: what do you gain from using both clay-based and volcanic materials? What properties does one group have that the other doesn't?

[@GrowingBonsai]

I used to only use the diatomous earth, but found it stayed too wet too long. So been playing around a bit, and found the expanded shale to be much drier. Now that I have a decent source for pumice, it is ever becoming more and more core to my mix, but so ugly white!

[@abydosianchulac2]

​​@@GrowingBonsai Actually, a follow-up question, Jelle. I can track what you're saying about how you use the three main sizes of substrate, but what about the remainder? After you winnow that lot to remove the sand and dust, what do you use those smallest particles for?
