Is Green treated wood safe for gardens?

How toxic is treated wood?

What happens if you paint treated wood too soon?
Yes – you can leave anything unfinished, but it will be just that- unfinished. Even the treated lumber will deteriorate and decay with time (though you could be looking at decades of use still)- and it will happen much faster if it is not sealed with a finisher like stain or paint or water repellant.
What is the difference between brown and green pressure treated wood?
The only difference is a brown stain added to imitate Cedar, a marketing necessity in the West where Cedar is inexpensive and popular for deck building.
What is the green on treated pine?
The preservation process of wood Copper and arsenic in the preservative protect the wood from insect and fungal attack. Chromium (chrome) ‘locks’ the copper and arsenic into the timber and reduces the risk of the chemicals leaching out. The CCA process gives the treated wood a green tint.
Is it safe to use treated wood for vegetable gardens?
Yes! Pressure-treated wood is safe for vegetable garden beds but with some precautions. The crops should be grown 10 inches away from CCA treated woods to prevent leaching of the chemicals into the plants. Heavy impermeable plastics can also be used to act as a barrier between the crops and the wood.
