Our charcoal is a clean hardwood charcoal. For use as a potting mix additive.
All plant's roots, especially orchids, need air or they suffocate and rot. Charcoal resists breaking down, so adding charcoal to your potting mix will help ensure an overly compact mix doesn't suffocate your roots.
Charcoal is an organic material and retains/releases nutrients to your plants, which is especially important when adding larger amounts of inorganic ingredients to your potting mix, e.g., expanded clay, pumice, or lava rock.
