experience with activated charcoal?
I just moved to a place where my c.p.'s look like they're suffering from soil toxins. They have to catch roof run-off and maybe even run-off from an upper balcony when it rains. It's the only place they can get enough sun. Anybody ever put activated charcoal on top of the soil of their C.P.'s? Wouldn't it help purify water that drips past it? I know in the wild most of them grow in areas where flash-fires are necessary for the ecosystem. i wonder why all C.P. soil mixes don't recommend charcoal? Something I'm missing?
