Question:
How do heavy metals help in promoting plant growth?


Replies:
Without knowing which "heavy metals" are being referred to, what is their chemical state, and what is the meant by "promoting" and which "plants" are being referred to, it isn't possible to provide a definitive answer.

Vince Calder


Actually, the situation is the opposite. Heavy metals can be a source of plant toxicity:

However, some plants can be used to remove heavy metals from soils.
