Making cement bonsai pots - super easy method

In this video, I show you how I go about making cement pots for my bonsai trees from start to finish

[@jackthefarmer08]

I'm writing from a place where the monthly basic salary is less than 300 dollars. A retired citizen is paid much less than that; 188 dollars, exactly. Hence, what you are doing in this video is much appreciated by those who accidentally grow bonsai around here.

[@TonysBonsai]

Hi Jack. Yes, I think anything that helps make bonsai more accessible to everyone is a good thing.

[@TheBonsaiZone]

Mad cement skills Tony!! I really enjoyed the video, very inspiring!!

[@TonysBonsai]

Thanks Nigel. I remember you saying that you like cement pots. I'm going to try to make some more refined ones in the future!

[@ranamukherji]

You come across as very humble; yet your degree of skill is very clear and obvious! Thanks for sharing. So inspiring and beautiful.

[@relationship_counselling]

A few of tips I've found useful: - Use a pinch of polypropylene fibres to frost proof the cement mix - I sometimes add perlite to the mix in bigger pots to make them lightweight - You can use polystyrene carved to shape to fill the hole in the middle of the pot for a better finish. Wrap it in sellotape if you want to reuse - use a vegetable oil spray or WD40 on the moulds as a release agent to get them out easily - It's important to leave cement pots out in the weather for 6 months before use so the rain washes out harmful alkaloids which can harm root systems.

[@relationship_counselling]

I forgot to add... be very generous with the amount of Mortartone cement colourant you use as it fades fast.

[@TonysBonsai]

Great tips there rhys! I bought some fibres which i tried in a previous experiment and I found that they seemed to compromise the strength of the pots although I am guessing that i added way too much. DO you literally just add a pinch?

[@relationship_counselling]

@@TonysBonsai it depends how much mix you're making, but a little pinch of the fibres goes a very long way. Add the fibres right at the start of your mix too so they get a good chance to disperse. Great video by the way 👍

[@rodericklippert1332]

Great tips! Thanks for those. I was planning on making a bunch of these over the winter and letting them cure in my basement, but now I'm thinking that when the weather warms up a bit(I'm in Michigan with cold winters), I can put them outside to get the junk leached out if the pots so I can actually use them come springtime

[@BalkanCrusader]

​@@TonysBonsaiNot sure if someone mentioned here, but if you pour hot water on plastic buckets, they will release cement.

You've inspired me to make cement pots. Great results man.

[@margaretsims4344]

Hi Tony. Interesting to see your cement pots. I have made quite a few Hypertufa pots for Alpines etc. the mix is Portland cement, Peat Moss and Perlite (or Vermiculite) in equal parts. The pots are a lot lighter than using a cement mix as there is no sand. They hold up well to frost and look a lot less like concrete, they are a much more natural look. I have many planted up with alpines and a couple planted with ‘bonsai’ Once the pots are dry after 24/48 hrs I soak them for a few days in a vinegar and water mix to leach the lime. The best moulds I found were extra large washing up bowls, but there are lots of shapes you can use. Lining the mould with polythene helps with removal of the pot when its dry. Making the drainage hole while the mix is still wet is so much easier than when its dry. You did Great job. You will find facebook pages for Hypertufa makers. Ps. Better to sift the peat moss to remove big bits of wood etc.

[@TonysBonsai]

Hi Margaret. I am definitely going to have to experiment with these hypertufa pots. It sounds crazy to me adding compost, but at the end of the day, if they work that's what matters!

[@dougporter1550]

[@timothyvanheerden8105]

Hi. Nice. I've been doing this for more than a year now. I changed over to using the wet sand as mold,same as your last pot. When i mix sand with the cement,i sift the sand beforehand. The one you use in the kitchen to sift flour. It comes out very smooth. For bigger pots i strengthen it with strands of galvanized wire.

[@TonysBonsai]

Interesting idea with the sifting Timothy. I'm going to explore this technique further, cheers!

[@jackiemikolaski4833]

Love the video. I find that it’s easier to get the cement pot out by turning the whole thing upside down and pouring hot water on it. The hot water relaxes the pot and the cement pot comes out easily. Thank you for making amateurs like me want to try new things without being intimidated.

[@TonysBonsai]

You're not wrong there. They are lovely things but they cost a small fortune once you start going over 40cm

[@shaolinshadowsoldier]

@@TonysBonsai It's my one complaint with the hobby. You can find or propagate the trees for free, you can find inexpensive tools, growing medium can often be obtained for free. Pots are another story as you know.

[@TonysBonsai]

Yes, I have hundreds of trees all in washing up bowls and plastic plant pots. It would cost me thousands of pounds to put them all in ceramics. I'm not sure what my solution will be. I have even contemplated buying a kiln and making my own.

[@shaolinshadowsoldier]

@@TonysBonsai I got some diamond tipped drill bits and had fun making holes in bowls from the carboot. That can work really well. I don't like plastic, it upsets me. Wood is nice, but it doesn't last. It's a real bottleneck for a lot of enthusiasts I think. Is this a supply issue?

[@TonysBonsai]

No, I just think it's a cost of production thing. When you factor in the cost of materials, the cost of firing to 1200 degrees C and then losses of pots during the process, they end up being expensive. I also suspect that the potters know that their customers can often afford to pay.

[@davidcanetti6927]

Tony you are an artist, we can buy pots from anywhere but artisticly you have to spend a lot on a pot that is different. Really love your work and videos dont ever change

[@claudiahawkins2648]

Tony thank you, I am going to do this. My favourite was the one you did over wet sand, the fact the edges were not the same thickness looked intentional and added something to it I thought. I want a pot to make a forest planting but the price of proper pots is at this time stopping that idea, I will be able work towards that now so cheers.

[@TonysBonsai]

Hi Claudia. I'm glad you're going to give it a try! I did another one using wet sand the next day (I didn't record it) and it went really well. If you pick yourself up one of those cat litter trays or something similar, you will be able to make yourself a super pot for your forest I'm sure.

[@tmister007]

At School I used to do Pewter and Aluminium casting! Many thanks for the great tutorial Tony!

[@TonysBonsai]

Go for it. It's great fun.

[@thejuanderful]

If you keep the concrete damp for a week while it sets it will improve the strength. Drying too fast makes it more brittle, but most people just dry it fast so up to the user. I like working with white Portland cement. Structurally it is the same, but it is more of a white colour instead of grey. I prefer the whiter look, and it is also takes less dye and produces sharper colour if that's the goal. White cement is about twice the price though which can make grey suddenly appealing. For de-molding professionals often use a special wax product to line the mold first but it's pricey. If you're trying to make a show worthy pot it might be worth it.

line the moulds with veg oil

I have tried that previously, and I think it did make them slightly easier to get out, so I think I will return to that technique in the future.

The only skip i know is a kangaroo mate, watched the concrete master all the way through. Good to see you being creative Tony, its weird timing as only 3 weeks ago i started to make my own pots with angle grinder and diamond blade to hollow out granite and quartz river rocks...a few sandstone too, its very dusty work and I've killed one angle grinder already but it was only 30 days old so they replaced it for me. The granite pots are so strong and when you concider the stones come from the center of the earth millions of years ago and been rounded by years of water flowing over them and shaping them...they are very special. I hope to sell some on ebay one day and become a millionaire!!

[@TonysBonsai]

Great to watch you making pots 👍🤗 There are definitley some take aways for me, as I'm creating my own cement-pots, for some while. My technique differs a little from yours, as I"m using quite liquid cement, soaking a towel and drape around /or inside my decided shape. Putting additional cement stepwise at the inside and outside up to the desired thickeness. This makes me able to keep my pots less heavy. Last outside cover, I like using some coloured cement. Putting a bag inside your buckets and bowls prevents the cement from sticking to hard. Looking forward to more videos. THX Kind regards from Austria 😊

I've dabbled in making cement pots. For molds i use plastic meat trays . recently I've been using plastic mushroom containers but what i do first is pour boiling water on them to melt them into odd shapes. Mine never really come out smooth on the outside which is ok they kinda look like lava rock! I also bought some diamond coreing drill bits to drill ceramic and other hard materials to make drainage holes in things i find at thrift stores. Baking dishes, soap dishes ,anything can become a pot or tray !

Hi Tony! 2nd comment 😘 You may use those not perfect pots (to thin at the edge, creapy holes in it) as a a base and fill up, in a second step, as you do with your walls, with fresh cement and using your gloved hands (as cement will soak and dry out your skin while exposition, up to chemical burns). You can ad structure by using a brush or just your fingers. The inside should be smoth without any crackings and holes, as your plants will send their routes in there and create a lot of troubles. 🙏🌳

You seem to have a massive amount of it in your possession, so you must be using it for something else - Is it a component of your Bonsai Substrate Mix ???? As a mould release agent, many KZbinrs use WD40 (the rich ones) or Vegetable Oil (us plebs) and others use plastic bags over the mould.

Hi Nikki. I bought two ton of the grano for laying flags on, and by the time I get round to finishing it I should use the lot. I have indeed been using it in my bonsai substrate, but I wouldn't recommend it as it compacts down and makes watering tricky. Much better to use a decent horticultural grit. Good luck with your pots!

Interesting work, but without Steelwire in the Zement, it will break in winter, i think.

It doesn't get too cold here in Preston, but it will definitely be interesting to find out!

Great video Tony I will be having a go at doing some .is there a sealant that I could paint on ...

[@TonysBonsai]

Hi Michael. I personally think that the additive I added with make them unlikely to leak anything into the soil, but I suppose you could always paint the inside with sbr. That then leaves a lovely waterproof finish almost like resin.
