This is a good price, but if you're constructing raised beds for a food garden, be aware that both this concrete and treated lumber will leach toxic compounds into the soil, and many leafy greens and fruiting vegetables will absorb some of those compounds.

Cardboard isn't entirely clean, but it's less contaminating than this, so lining the interior of the bed with broken down boxes (stripped of tape) before filling can help. The bulk of the contaminants will end up running off into the surrounding soil as the cardboard breaks down.

Better still, use untreated wood and put a segment of wood over the concrete on each corner... but untreated wood will frequently rot in 4-5 years.
I like em, but these may be a loss leader to get you to buy lots of 2x6 or 2x12.
I can't find anything that showed real numbers of actual issues with some concrete blocks other than concept and theory other than maybe a slight increase in pH initially and this is not minor incidental contact on the corners this was concrete mixed in the dirt. The actual dirt in your area is a factor. If I want to believe concrete in a few blocks is or is not an issue you can find a lot of non scientific papers, comments, theories etc that can reinforce your thoughts on both sides.

Quote from Johngcp :
Might wanna update your info. Treated lumber practices have changed since it's been popular to use the wood in raised beds and the toxic chemicals are no longer used to treat the wood. Also cedar is a great untreated wood that will typically last much longer. Roughly around 15 to 20 years plus because it's naturally rot and pest resistant.

I'm a big fan of cedar. I actually used cedar fencing for a series of raised beds, but cedar fenceposts are no longer available where I was, nor where I am. Even a half inch thick cedar is fine for a raised bed if you reinforce the outside every 2-3 feet.

Quote from BraveStraw727 :
i buried a lot of cardboard instead of expensive soil for my raised beds, all 3 of us can agree to that.
I used the standard hügelkultur method, not for the sole reason of the standard itself but because it just made sense for me. My beds are about 28 inches so tossing in logs, old mulch, and sticks/leaves was free and easy. One thing that did not pan out for me was the moisture. Even a few years later, my raised beds dry out QUICK. I need to water them almost daily. My garden in the native ground in the same general area I only have to water in the extremes which may be 1-2 times a month.

Quote from Joeggernaut :
warranty on treated wood? I don't think anyone warranties treated wood and that would be a bogus claim to make warranty when the manufacturer knows people cut treated wood for decks/etc. The MCA 2x6 I bought is not ground contact rated and I knew that. I line the bottom of the wood with landscape fabric but don't really expect it to make that much of a difference. Not hard to replace boards when needed. Plus I did 2 rows high in sections. I can simply remove the bottom row section and the top board will drop down if needed. At the end of the day, is a cheap way to make a raised bed and I wasn't really concerned about any warranty.

I did drive 1/2" x 2 feet rebar through the hole in the middle of these and into the ground for added stability even though I only went 2 blocks tall. I then topped the perimeter with 2x6s on top of the blocks screwed into the wood walls like you see in the example pictures.


Also the Miracle grow raised bed soil is junk in my area (I believe is locally sourced) and mostly just mulch. Better off getting real soil from a local place. Either way you want to mix it with your existing soil.
Google is your friend...search "treated lumber warranty" and you will find hundreds of warranty articles

These things are great. I have several raised beds built of these and 2x6s.
Full disclosure, I didn't know what these were and clicked on it to see...I read this comment and wondered if you used it with box springs or as a platform bed with memory foam.

Please use treated lumber. No need to get untreated lumber. Exposure to far more chemicals than "leaching" while using a public bathroom, walking across a parking lot, waiting for a train/bus, living within five miles of a nuclear plant, etc. 😁
You do know you get more radiation inside your house from natural sources than you do walking around inside a nuclear plant, right? They are pretty serious about shielding, it's not like the movies.

Yeah, I'll concede I was relying on outdated information about wood treatment, but even what you get from leaching from standard quick dry concrete (mostly trace metals in the limestone powder used for Portland cement) against soil in higher humidity conditions, taken up by plants and ingested, is usually much worse than the environmental exposure this guy listed here, unless you live in a significantly polluted urban environment... or probably anywhere in Texas, given the shale mining...

I realize they say only intended for 2' high but unless these have some metal lattice inside Id expect them to break under a little stress and moisture at the board slot. We usually also slant retaining walls a bit to lean into the soil. I don't know... rocks are free on the side of back roads around here for small projects. Gravel quarries often sell larger non crushed limestone rocks for cheap.

HomeDepot have the same block. They will match the price if you show them the screenshot.

I've also done the research and I'm unbothered by these blocks

These have a hole in the middle for a piece of rebar. Not very stable without the rebar from my experience.
Agreed. I've but admit 20 beds with these, and every single one without rebar has topped.
I ended up replacing the corners with 4*4s when I couldn't add rebar
