New treated lumber isn't near as "treated" as the older stuff. But I'd advise against using any of it for raised beds, the chemicals will leech into the soil. I've found cedar fence planks to work well. They used to cheap, probably not now. But they hold up well, mine are going on 9 years now. But I did rip some treated 2x4s for the corner braces.
I've wonder the same, but it on there to protect the wood. So it not like it will lose it fast . I've got a couple beds made of it, not too worried now. Haven't heard or read anything that says not to use it yet.
If and when I go the raised bed route , it'll be for next year. As of now it's just a "maybe."
If it’s relatively new it’s considered safe. The formulations changed in 2004, if it’s older than that, I wouldn’t do it.
I use so little the bottle is over half full. But it is "newer" than 2004.
I don't know? I can't get anyone to try it.Tea from cow manuresweet or unsweetened
Just don’t tell them what it is.
In my experience it’s the soil temperature I worry most about. Wind burn is definitely a problem, but when I’ve planted early in cold soil the plants just won’t grow and are stunted. It’s going to be freezing or below for the next 3 nights, 25 tomorrow night, so I’m glad I held off. Not sure how badly this will affect all the trees and plants already leafed out, including my fig tree, blackberry bushes, and muscadine vines. Fingers crossed.
Have you tried using milk jugs for a little hot house? Plus protection from the wind
Those work well.
