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.

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 don't know if you'd classify this as misinformation or incomplete information, but currently available treated wood does not contain arsenic like the older versions did, and it is considered to be safe for garden beds. Here's one link, while an easy Google search will yield many more sources saying the same thing.
https://www.lumber.com/blog/what-...%20arsenic.

That all said, I've gotten a number of years out of standard untreated construction lumber before it degraded in ground contact situations. And as someone else mentioned, cedar is naturally rot and insect resistant, and cedar fence pickets are a fairly cheap alternative I e used before with some success. These days I trust the experts and use treated though, since the current stuff has been on the market for a while without any significant danger coming to light.

How about this? I have them. I've changed it my beds over the last three years with them. I use untreated wood 2bys.

They're awesome. When you need to swap out the wood, it's easy. Pin them with a piece of rebar. Everything grows great in them.

I would like to use these to make 2ft x 2ft planter boxes. What wood can I use so it won't rot quickly? Is it safe to use pressurized wood or should I use other wood and paint/seal its inside. I won't plant any fruits/herbs, only succulents or evergreen plants

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. 😁

Untreated pine has lasted about 5 years here in east coast 7a (this region might have migrated to 8 in the past few years, not sure) in raised beds, direct contact with soil.

And two screws in the ends has been pretty easy and effective.

Buying 1000x to build a Castle in Cali. This is way more affordable than a tiny house. Now just gotta find the right street corner. Thank you OP.

These have a hole in the middle for a piece of rebar. Not very stable without the rebar from my experience.
