Will a galvanized container leach Zinc and "Trim" the roots? Are there other effects?

Question

I have heard that a galvanized container such as this one for a raised bed will leach zinc and "trim" the roots. What do they mean by this?

Would the increased zinc be bad for raising food plants? I was planning on growing bamboo in them but having a couple more for food plots would be awful convenient.

Answer 1

Zinc should not be a problem it may raise zinc levels by a minimal to negligible amount. Some galvanized containers may contain cadmium, although not so much a risk in plant uptake, but you will want to make sure you wash your hands and crops well before consuming.
