The box I cobbled together from old pallets, dirt is a mix of potting soil and local dirt spiced with chicken poo.
For the more observant viewers, you may notice that the closest 'V' is slimmer than the upper square -- the pallets were a little short. I plan to plant smaller vegetables in those areas.
From what I understand, that's dangerous for gardens. Old pallets have likely been subjected to some of the most dangerous carcinogenic chemicals over their life.
I'll add it to my microbiome of plastic.
Even just pressure treated wood is not recommended for veggie use.
The soil and water will leech chemicals out of wood and your veggies that you eat will absorb it.
I hate seeing all these crafts and people bringing the stuff in their houses, unless you source the pallets from someone trustworthy, they could have oil spilt on it for all you know.
Wood treated with Copper Azole is safe for garden beds. We've pretty much stopped using arsenic based compounds to treat wood. And plants don't tend to pull in copper (it's even used in some pesticides sprayed directly onto plants)
May not apply in your country*
And people use reclaimed wood all the time, unless you source it yourself, you have no idea unless the rating is still legible.
Also, some people avoid pesticides, so they would also want to avoid it in their frames too.
Copper is an essential plant macronutrient, so that’s just plain bullshit.
No more than they normally do. They've done studies on this. There's no extra copper in the plants due to the presence of this pressure treatment on the wood using copper azole
I never said there was…
There’s also additional chemicals to just the copper dude….
Copper is a macronutrient, you want in your soil. So I don’t know what point you’re trying to make here?
The point is that modern pressure treated wood is treated with copper, so unless you think copper is going to be bad for the soil/plants, modern pressure treated wood is safe to use for garden beds.
