All REALLY good suggestions. Always keep in mind what separates a “Pro” from a “Joe”: The “Pro” already got a lot of mistakes out of the way. That’s why pro’s get paid. You pay them for the mistakes you didn’t have to make on your own. Nobody hits the ground “just knowing”. Everybody learns.
@@burnerjack01 With YT nobody has to be a "Joe" anymore! In fact with YT one can often do things better than the average Pro, including making this planter, if one studies all the comments diligently. Thanks to all concerned!
Indeed, its refreshing to see a video from someone who is not an expert and is showing all the issues he faced as well.so much more helpfull to prepare for the challenges trying this out as well.
Thank you for an "honest" video. It's encouraging, a lot less intimidating. A lot of videos are made where we don't see the first try or that a better method can be used. Thank you for that. I'm much more inclined to try and mould a planter now because the pressures off. Nothing wrong at all with Wondermen ... But all too often they're not around! 😆
Great Job Teddy. I know how much those planters can cost. You'd have so much more pride in making your own no matter the outcome. It looked great and for those of us just starting out it's very informative. A lot of people near my home dump old things on their nature strips. Recycling their rubbish is a fantastic idea
Most comments are spot on about tapering, oiling, finishing. I would add perlite to the concrete mix to make a lighter planter and you might consider adding some type of wood shape inside each outside panel to make an inset on each side to also reduce weight and make the planter much nicer to look at. Lets face it an empty planter should be light enough to move around and position where you want it.
THANK YOU TED! It's BEAUTIFUL; REALLY. I THINK IT'S AWESOME AND FOR A FIRST TIME ATTEMPT . . . WOW! THANK YOU SO MUCH FOR TAKING TIME TO SHARE! I REALLY APPRECIATE YOUR TIME AND EFFORT. IT'S A GREAT "LEARNING" EXPERIENCE FOR ME.
I have watched millions of learning videos since 2006 and am subbed to thousands of channels,you've definitely created one of the most informative videos I've seen. I'm going to do exactly what you did but I'm going to built it for a safe
Nice planter. Just a note, if you wipe oil (any kind), or spray with PAM cooking spray, or line the inside with plastic - the concrete won't stick to your mold. Hope that helps.
I've watched other videos, it doesn't work. The concrete probably just absorbed the oil in and then stick to the wood. Everyone who used oil still had to fight to get the mould off. Imho, if you're ok with plastic bag fold Mark's the best thing would be to line the mould with some cheap tarp or maybe even self adhesive carpet protectors that you lay on carpets for painting and decorating.
Melamine for your frame works wonders when it's time to release the mold from the concrete. It's a little pricey, but saves a lot of time foe the project. Your container looks great!
I liked your video because you show the little worries, matter or situation , that we, beginners sometimes need to dealt with, in making this arts, and overcome. Thanks
I loved your video. I can't believe how snarky so many of the the comments have been. One of the greatest things about a diy video is the helpful and informative comments sent in that we all can learn from. That's why we read them. Thank you for making this video.
I think you did exceedingly well considering all the problems that occurred toward the end. You were cool, calm and connected, and resolved the issues. The plant pot looks great, and altho I don't plan on making anything near as large this summer with cement, your issues with the pot allows us all to learn from them. You did well; altho I'm not an expert in cement projects, I'm merely a portrait artist, I thought the video was super. Thank you for sharing your work of art. :)
@@sabel146 I don't remember ever watching this video, but obviously I did. I admire people who at least try to make, create or do something they've never tried before, and in this guy's case he did an excellent job for a first attempt. It's amazing what we can do if we try. :)
I used vaseline as mold release and it worked great! You could taper your inner box similar to a draft angle. Even 10* of an angle would make it easier to back out. Great video!
sean christian Your right. I wondered how everyone missed that the entire issue was the draft angle of the inner box. At 90 degrees it would almost be impossible to pull out.
Nice job on the video. I’m considering building a mold also and found your step by step very helpful. Thank you for sharing, lessons learned, etc. cheers!
One thing you can try is wrapping your inner box with cardboard and masking tape. It compresses to compensate for the concrete shrinking as it dries. You can usually put the inner box straight out of the mold. Use a pressure washer to remove the remaining cardboard or just leave it because it will desolve eventually.
Man, people in the comments need to learn humility, not everyone is an expert and everyone has to start somewhere. Someone will know more than you in something so don't be douchebags with what you do know. Anyway, thanks for the vid :D Not making a planter but definitely gave me an idea on making cement molds. Cheers!

Lance Uppercut yep everyone’s an expert but non of them make videos 😁
Your thoughts are kind. But I do appreciate seeing him work through his first attempts, with the glitches - then hear the others pitch in. It's like being among friends.
Hi teddy. Good idea. I build catch basins for syorm drsins. I cut my forms into pieces beforehand to make easy to strip. Cleat togather. It works well, and you can reuse your forms.
I've been watching TH-cam how to make large pots instead of wood on the bottom put some sand on the bottom get it damp with water then add cement the thickness that you want . Take a pvc pipe push it through the bottom then pull it out . now you have hole for the drainage I loved your video thank you .
You did Great ! One piece of Advise .. Use spray on veggie oil or a light oil base on the porous Wood to keep the Concrete from sticking Makes removing the Forms So much easier . Nice work . It’s a Labor of love to make a Planter like this ❤ 🏡 🪴
I worked at a pre cast concrete product manufacturer temporarily, I'm not an expert, anyway we used cooking oil in a chemical spray bottle, like you use for weed killer but industrial (metal) instead of pumping it we used a compressor to pressurize to lube the forms and molds. We were making bulk products, a plastic sprayer might be fine for your needs We inserted desired lengths of metal rods immediately after pooring the forms, much thinner than rebar. We had a hand held electric vibrator we simply held to the forms make sure it settles in, fills all areas properly and gets the air bubbles out. I enjoyed my brief introduction to making precast concrete products.
I like that you share what didn't go as you expected, and what you planned to try differently in the future....y'know, like what the rest of us actually experience. . .! :-)
Hey teddyd30, I love how much effort you put in projects like this one. I hope you'll also make a video showing what you plant inside the planter: hope it'll be something cool!
Ted! This is amazing! What do you think of the idea to build this upside down? I saw another video of a man who build one and added 4 wheels to the corners from building it upside down. I thought that was genius. This is beautiful! Thanks for sharing!
Doing it upside down you would need a very solid plank for the base, else the weight of the concrete would depress the form, and maybe interfere with the setting of the material, i.e. if it is settling / moving constantly under gravity
When you make the next one make the inner box tapered and only let it stay in there a few hours, the bottom width both directions about a half inch smaller than the top. By tapping on it a little and pulling it up it should pop free and slide out. The concrete will have set up enough to hold its shape. Also on the strips of wood for the bottom, taper them as well just a little bit and they will pop out pretty easy too, on these the bottom will be wider than the top, 1/8th inch should do the trick. You should also be able to deform the outside after a couple days. No need to wait a week. Looking Good!
Ya, this guy's saw only cuts at a 90 deg angle. He really needs to learn about champher. (I need to learn to spell). Should have put a triangular molding (90/45/45 degrees) at inner corners so inner plywood comes out parallel to adjoining sheet (no overlapping). Molding is lost with each cast but ply is not. Would have dressed up the outside as well, top corners...
@@joewilliams7783 Not even that hard, you just need to learn how to check spelling with google (just type the word however garbled into the search box and hit return😂 the correct spelling will appear)
Thanks for making this video. I especially liked those side channels at the bottom. A good idea I intend to incorporate in mine. Think I'll use styrofoam strips, though, so I can just dig them out afterwards with little fuss. Thanks again.
@@tedsbackyard The weld-mesh would push the price right up, but would make the perfect product. What would be the minimum wall thickness for that size of planter?
Here is a tip for you. Oil all forms first. Car wax works well too. Use hinges on form bottoms then tape over them to prevent leakage. Remove tape, let’s air in to break the vacuum, hinge makes it super easy to remove bottom without breaking forms. Reuse!
Wipe the surfaces down with waste oil next time, that is what we used on wooden forms for concreting. With the innerbox make the sides overlap the base and not the base over lapping the sides and affix with screws so you can unscrew from the inside. Only need the inner form for the first few hours, no more than 24. The other you can leave for a bit longer if wanted. Nice work.
you could also use a masonry disc on an angle grinder to get the concrete "bumps," but much better to float the top with a trowel after filling with concrete. Also, a thin rebar length should be used to get the bubbles out, like in the old days.
Just buy the raw ingredients separately (if you can discover what they are and the ratios), you will save 50%. I assume the mix is 3:1 sharp sand to cement. Not sure about the fibre reinforcement material.
Very expensive to buy ready made, and then there is the additional huge expense and logistics of the delivery operation. They don't fit in the mailbox😂
Some 1/2" schedule 40 pvc is a cheap way to move almost any heavy smooth surface object. I moved a 1100 lbs safe across my garage with two sticks of schedule 40 1/2" one handed ....nice video. thanks and a cheap orbital sander cheapest one you can find will get air bubbles off the form surface...
Used engine oil or vegetable oil can be used as a release agent. You can also make a slurry of mortar mix like a sandy latex paint and brush it over the outside to fill the air pockets, or if you want it smoother a similar "paint" of portland cement and water will work as well.
Great job for a first time planter! The good thing about these planters is they look great almost any way they turn out! Not sure if you answered this question in another comment, but I'm curious to know how much this mammoth of a planter weighs? That would undoubtedly be my husbands first question. Without dirt and the plant, were you able to move it to a spot you were happy with without using a crane? Thanks for sharing... the planter looks excellent!
I think it weighs 640 lbs. I used wedges, levers, and rollers (ancient Egyptian style) to move it where it needed to go. I made a second one and had the foresight to make that one in the place where it would end up.
@@tedsbackyard Wow! That's an incredible weight! I made several concrete pots and garden spheres this spring to add interest and texture to my garden, and they were also a bit heavier than I anticipated. Glad you were able to get your planter placed, and still adventurous enough to make a second one. Thanks for your reply... enjoy the summer!
@@tedsbackyard That is one huge advantage of making your own, if you buy one ready made it's very difficult and expensive to have delivered. How do you move one of those from roadside to your garden? But you can easily carry bags of sand and cement to the exact desired location
yes I know your video is a year old but some people don't have people skills or know how to explain, but regardless u can use diesel fuel to spray on your mold's, cooking spray, there are other options as well, but you did a good my compliments sir
When I built one of these concrete planters I did not have a bottom on the inside box. I used 2x2 in the inside corners of inside box with all the screws from the inside to make removing screws from the inside box easy and reusable to make another box. PS I used a releasing agent (vaseline) on all wood in contact with concrete.
This is very similar to forming the sump pit in the floor of an elevator shaft. Next time just eliminate the bottom form of the inner box all together. Pour the bottom and just let that set up for a few minutes, then continue pouring the sides. Or use a solid block of styrofoam for the inside form. Any solvent like gasoline will dissolve the styrofoam. No smoking!
That sounds hideously environmentally damaging. But styrofoam is disgusting stuff possibly best burnt, else it's indestructible and will probably end up floating in some ocean
I made a planter like this 10 years ago. I used 4 bags of cement each weighing 92 lbs. after it was finished I could not move it. You better cast it where it’s going to sit forever.
Awesome video! Looking back, do you think you would have tried to make it a bit thinner, maybe added some steel reinforcement? It looks great for a permanent spot, but I'm wondering if you think it could have been a bit thinner and lighter? I want to make one, but would need it to be fairly moveable. Looks great and it came out great! especially from salvaged material. Good work and thanks for video!
nice video, good instructions. You missed the release agent part so the mold can be removed without being destroyed and available for future planters. Thank you Teddyd30, I learned some ideas from you, I try to make concrete planters all the time.
A lot of sound ideas and great inspiration here! Thanks for sharing your process. How about fashioning the planter upside down in the form? I am positive there is spray on release agent made specifically for concrete forms. I’d ask a pro, but I believe melamine forms release much more easily. I would wrap my form in cling film. As for as aesthetics, I love your square project, but I would want to stick colored glass into the top edge while it was wet. I agree that the bubbles are attractive. If you needed a smooth finish, you could make a thinner concrete mix and trowel it over, like plaster on a wall. Next time, play with concrete pigments! Planters that size or heartbreakingly expensive, so I applaud this DIY endeavor!
I built some planters 4'x4'x 2'6",on my lawn at the edge of my patio for some reasonable sized fruit trees. Being right near the sea and sandwiched by a lake half a mile behind, the ground isn't the most solid and they needed a raft type footing according to the very young planner guy who also gave me some tips.Being a bit old fashioned and an automotive electronics tech by trade,so not knowing any different assumed that because his of young age that when he said feet he meant meters. Incidentally I built these massive footings about 3 times their required size according to the bricklayer who was building our shed, I didn't tell my wife😁 they haven't moved though.
What is a "reasonable sized fruit tree"?😂 Or what would be an un-reasonable sized fruit tree? Is your house called Mar-a-Lago? I think that is the rationale for the name of Trump's place
Motor oil works the best for making sure surfaces don't adhere to the concrete. I have approached local mechanics and asked for some used oil and they were happy to give it away.
When mixing mortar in the tub ,(1) put the water in first ,the amount is written on the bag,This makes it a lot easier to mix ,(2) Best bet, Mix the mortar in a bucket using an electric drill ,mortar will come out like a smoothie with less air bubbles
You can use a metal grinder and a grinder (not a cut) or sand blade to shape the concrete. Good for large details. Wear safety equipment, the stuff flies everywhere.
Fiber reinforcement is just fiberglass added to the mix to reduce cracks in the fine finishes of small projects like yours. Developed I believe, for concrete countertops to reduce small surface cracks, its used a lot in moulded ornamentals like birdbaths, fountains and planters and concrete garden art pieces.
in construction we brush the plywood with diesel before we pour concrete, for this small project you can use motor oil (for the wood to come off easily, and not stick)
I used plastic sheet over inside box and the pot was very good.For out side I used two big sheet and two small sheets and made the box by screwing each other.It It is easy to dismantle box after finishing the work.
For new viewers, I reviewed the comments, sumnarised here
1) Cooking oil as a release agent got a lot of mentions.
2) Needed the sides of the inner plug to be sloped inwards for ease of removal.
3) Use a concrete edge finisher tool on the top edge before it sets.
4) the water channels on the bottom are way too small. They need to be bigger to stop being clogged over time.
5) Some wire for reinforcement may be a good idea at the bottm and at various levels
6) Vibration on outside for better bubble removal, as you mentioned.
7) Plastic tape on all inner corners for smooth edges, and tape over all the drainage molding strips.
8) no need for bottom inner mold bottom. Just level the first few inches and then set the inner walls on top.
Nothing like practice for perfection : -)
Thanks!

Looks fantastic. If you wanted to make several the same you could construct out of marine ply and re-use the formwork.
It is the alkalinity of concrete that destroys plywood, not the water. Paint the inside with 50/50 bondo and oil based paint to get up to 100 uses.

Hey, we use to build houses with concrete forms. We sprayed the forms with diesel oil and the forms would peel right off the concrete.

Just buy the raw ingredients separately (if you can discover what they are and the ratios), you will save 50%. I assume the mix is 3:1 sharp sand to cement. Not sure about the fibre reinforcement material.
That, Sir is a definite success :D Thanks for the video
Awesome!! I need 2. Sent my hubby the video, we will see.
Thanks! Any update???
that's a badass planter!
Excellent Video ! Thanks for this ! You gave me ideas !!
I would like to make one myself for a pond/waterfall piece. Nice video tutorial
Great job dude.... Looks mint.. 😊
So how much did this cost to make in the end, inc concrete, sealant, wax etc? $100? how much are they to buy new?
I think it was about $80
Very expensive to buy ready made, and then there is the additional huge expense and logistics of the delivery operation. They don't fit in the mailbox😂
Some 1/2" schedule 40 pvc is a cheap way to move almost any heavy smooth surface object. I moved a 1100 lbs safe across my garage with two sticks of schedule 40 1/2" one handed ....nice video. thanks and a cheap orbital sander cheapest one you can find will get air bubbles off the form surface...
Used engine oil or vegetable oil can be used as a release agent. You can also make a slurry of mortar mix like a sandy latex paint and brush it over the outside to fill the air pockets, or if you want it smoother a similar "paint" of portland cement and water will work as well.
beautiful, i want to try to do one for my yard.
do u think it is too thick. if you put some of the metal reinforcement you may not need to make it that thick
You didn't put steel bars or wire mesh as bones or for structural strength?
Thanks for the educational video. You think it might work better if the mold surfaces were coated in stick on plastic film sprayed with Pam?
what a monster of a block, .. how heavy was it?
Great job for a first time planter! The good thing about these planters is they look great almost any way they turn out! Not sure if you answered this question in another comment, but I'm curious to know how much this mammoth of a planter weighs? That would undoubtedly be my husbands first question. Without dirt and the plant, were you able to move it to a spot you were happy with without using a crane? Thanks for sharing... the planter looks excellent!
I think it weighs 640 lbs. I used wedges, levers, and rollers (ancient Egyptian style) to move it where it needed to go. I made a second one and had the foresight to make that one in the place where it would end up.
@@tedsbackyard Wow! That's an incredible weight! I made several concrete pots and garden spheres this spring to add interest and texture to my garden, and they were also a bit heavier than I anticipated. Glad you were able to get your planter placed, and still adventurous enough to make a second one. Thanks for your reply... enjoy the summer!
@@tedsbackyard That is one huge advantage of making your own, if you buy one ready made it's very difficult and expensive to have delivered. How do you move one of those from roadside to your garden? But you can easily carry bags of sand and cement to the exact desired location
yes I know your video is a year old but some people don't have people skills or know how to explain, but regardless u can use diesel fuel to spray on your mold's, cooking spray, there are other options as well, but you did a good my compliments sir
When I built one of these concrete planters I did not have a bottom on the inside box. I used 2x2 in the inside corners of inside box with all the screws from the inside to make removing screws from the inside box easy and reusable to make another box. PS I used a releasing agent (vaseline) on all wood in contact with concrete.
Nice job. This is what i need!
This is very similar to forming the sump pit in the floor of an elevator shaft. Next time just eliminate the bottom form of the inner box all together. Pour the bottom and just let that set up for a few minutes, then continue pouring the sides. Or use a solid block of styrofoam for the inside form. Any solvent like gasoline will dissolve the styrofoam. No smoking!
That sounds hideously environmentally damaging. But styrofoam is disgusting stuff possibly best burnt, else it's indestructible and will probably end up floating in some ocean
I made a planter like this 10 years ago. I used 4 bags of cement each weighing 92 lbs. after it was finished I could not move it. You better cast it where it’s going to sit forever.
Awesome video!
Looking back, do you think you would have tried to make it a bit thinner, maybe added some steel reinforcement?
It looks great for a permanent spot, but I'm wondering if you think it could have been a bit thinner and lighter?
I want to make one, but would need it to be fairly moveable.
Looks great and it came out great! especially from salvaged material. Good work and thanks for video!
The weight might be an advantage i used as a barricade.
nice video, good instructions. You missed the release agent part so the mold can be removed without being destroyed and available for future planters. Thank you Teddyd30, I learned some ideas from you, I try to make concrete planters all the time.
A lot of sound ideas and great inspiration here! Thanks for sharing your process. How about fashioning the planter upside down in the form? I am positive there is spray on release agent made specifically for concrete forms. I’d ask a pro, but I believe melamine forms release much more easily. I would wrap my form in cling film. As for as aesthetics, I love your square project, but I would want to stick colored glass into the top edge while it was wet. I agree that the bubbles are attractive. If you needed a smooth finish, you could make a thinner concrete mix and trowel it over, like plaster on a wall. Next time, play with concrete pigments! Planters that size or heartbreakingly expensive, so I applaud this DIY endeavor!
"spray on release agent" = gentleman's waste diesel😂
I built some planters 4'x4'x 2'6",on my lawn at the edge of my patio for some reasonable sized fruit trees. Being right near the sea and sandwiched by a lake half a mile behind, the ground isn't the most solid and they needed a raft type footing according to the very young planner guy who also gave me some tips.Being a bit old fashioned and an automotive electronics tech by trade,so not knowing any different assumed that because his of young age that when he said feet he meant meters. Incidentally I built these massive footings about 3 times their required size according to the bricklayer who was building our shed, I didn't tell my wife😁 they haven't moved though.
Some things the wife just doesn't need to know👀
What is a "reasonable sized fruit tree"?😂 Or what would be an un-reasonable sized fruit tree? Is your house called Mar-a-Lago? I think that is the rationale for the name of Trump's place
Taper everything to help disassembly.
Great video. Primer sealer is probably just PVA .....watered down glue 🇬🇧
Motor oil works the best for making sure surfaces don't adhere to the concrete. I have approached local mechanics and asked for some used oil and they were happy to give it away.
When mixing mortar in the tub ,(1) put the water in first ,the amount is written on the bag,This makes it a lot easier to mix ,(2) Best bet, Mix the mortar in a bucket using an electric drill ,mortar will come out like a smoothie with less air bubbles
Thanks for the info!
I've been wanting to do this. Thank you!
Good job brother
Thanks for sharing God Bless U
looks great !!!!
You can use a metal grinder and a grinder (not a cut) or sand blade to shape the concrete. Good for large details. Wear safety equipment, the stuff flies everywhere.
Great idea. I can now make my own at a much more affordable price.
Don't make it this thick. This was overkill. I was just showing y'all what I did.
Fiber reinforcement is just fiberglass added to the mix to reduce cracks in the fine finishes of small projects like yours. Developed I believe, for concrete countertops to reduce small surface cracks, its used a lot in moulded ornamentals like birdbaths, fountains and planters and concrete garden art pieces.
What sand do you need to make this pale concrete. I was told locally I’d need builders sand which is dark and wouldn’t give the colour I want.
You need sharp sand, always ends up grey when mixed with cement, unless you use white cement
A diamond tip masonry blade on an angle grinder will make short work of those high spots!
in construction we brush the plywood with diesel before we pour concrete, for this small project you can use motor oil (for the wood to come off easily, and not stick)
I used plastic sheet over inside box and the pot was very good.For out side I used two big sheet and two small sheets and made the box by screwing each other.It It is easy to dismantle box after finishing the work.
great work !thank you
Tip: if you put spray canola oil or any oil all over your wood before pouring it would have come out without a struggling. Nice job
was this all one bag/one batch of concrete?
Great job, should have put some kind of metal reinforcement.
nice work!
Nice job. Thank you for posting!
