Stop warping in pine planks

Does anyone have a tip to prevent warping with pine planks? These mini-beds are only a few days old.

Unfortunately, Doug, it would be nearly impossible to stop that warping without having put heavy supports inside the corners. Adding 4"x4" uprights in the corners and securing the outside boards to them will keep them in place, like this:

And, be sure good quality patio screws, not nails, similar to these screws:

Some of my 2"x8" lumber does the same thing and they are secured with long deck screws. While it bugs me, it doesn't seem to make a difference with growing.

Here's a 1"x8"

First, stop using raw Pine. Cedar.
Second use a sealer like linseed oil.

It's been a while since I built a new bed, but for my 4x4 beds I used 1x7" PVC boards from Lowe's. It never rots, I don't think there is anything toxic (it's pvc). And for a 4x4 bed, it's strong enough to not bend too much without bracing

Has anyone had any luck using these corner blocks? I bought 4 of them and new boards to rebuild one of my 4 x 8 beds.

Yes, Yolos Sad

used them for a flower bed.

I saved this photo from a non-SFG site.

Using rebar in the center holes can help keep them together or aligned.
