What metal is toxic to plants?
Cadmium is highly soluble in water with a long half-life; therefore, it accumulates in soil and is potentially toxic to plants. Thus, when it is absorbed by commercial crops, it is a risk to plants used for human or animal consumption [125].
Is it OK to plant plants in metal pots?
Metal planters are too risky for outside and inside plant health. On the outside, excess heat can burn and damage the soil and the plants. Inside, the metal can rust and cause oxidation to occur at the bottom of the plants, rusting them too.
