Lucky. Tropical Plants & More keeps me busy in my retirement.
No, Black Kow is added just for its compost-basis. It also provides very low-dose fertilizer and it will never "burn" your plant's roots. It actually would be pretty much the opposite of something well-draining, though I have a feeling that it has sand in it so it does drain. Perlite opens up the potting media for that (draining). Oddly enough, just this very moment, I returned from Lowe's and brought home three bags of the Black Kow and three bags of the milled sphagnum. That's 12 cf. and it won't last the month. Those two items make up 2/3's of my general purpose potting media. I will mix a bag of each, plus perlite, plus Osmacote in a large wheelbarrow and use that mixture when re-potting. If I want to open up the mix even more, I'll add a good measure of chopped cypress mulch. That super-open mix would be used for my terrestrial orchids.
