If the anthurium plant is at least a year old, it may prefer an even coarser material, achieved by adding a handful of crumbled aquarium charcoal, coarse river sand, or small pieces of broken brick. Ending4: These materials may have a tendency to mix out of the leaf gland, but you will be able to work on this unbacteria-resistant soil without any problems.
