Innovation for Easy, Inexpensive Raised Beds

It's a concrete block that sells for $3.38 each. Cost is about $12 and change for each bed plus your lumber cost. Available at Loews, HD, plus other outlets. You can see the block on the corner of the opening scene on this youtube video:

The following was just published yesterday at NY Times. I tried to "gift" it but there was no option. I'm hoping because it's Wirecutter it will come through for everyone:

These Lego-Like Bricks Make Building a Raised Garden Bed a Snap

Being a Wirecutter writer, I'd love to tell you that I obsessively researched the subject before building my garden beds. I didn’t. Instead, my partner was at our local home-improvement super-center and stumbled upon Oldcastle’s planter wall blocks.

"Hey," she texted me, alongside a photo. These look like they might work?"

While she browsed the tomato starts, I scoured YouTube. I quickly discovered that people really love these bricks. In video after video, gardeners of all experience levels gushed over the simplicity and cost-effectiveness of these concrete blocks, and they shared tips on how to put them to best use. I was convinced. I rushed outside, measured our space, and texted her the dimensions. Several hours later (yes, that same day), the beds were complete.

As it turns out, I wasn't the only Wirecutter staffer who was bewitched by these marvels of modern engineering: Two of my coworkers were building their own block-based beds at the same time. In the end, all three of us were impressed by how cheaply and easily our gardens came together.
