I have a Kohleria plant and a C. Lindenia (two tropical plants not normally found in nurseries; both are related to each other; found them at a plant show) I found metal pieces/flakes in the soil that I do not think were there when I first got them. I watered them yesterday and they both smell like iron/metal. The water that ran through them is yellowish in color. Is my plant making its own metal?
No . Plants dont make metal Must be something in the soil.
Probably just vermiculite. (I probably didn't spell that right.) Comes with the soil. Not to worry. Now if it starts making gold, we will all be right over.
usually those tin-like flakes are found mixed with fertilizer.
