WaterWitchin, you summed up the reason I use charcoal. It does not rot and keeps the medium open. I have made my own charcoal for a couple years (easy to do in a charcoal grill). That gives me charcoal that is virtually free, and I have control over what it's made from. I really like homemade bamboo charcoal (think charcoal cylinders with all that open space in the middle). Sometimes the cylinders break into chips but those are useful too.
I agree with you. Orchids seem to really like charcoal. Each year when we burn brush in our yard I keep the larger pieces. If I don't have enough I use lump charcoal.
Jeremyinsf... Will you adopt me? I come with my own TempurPedic.
Now I'm off to sweeten my potting soil with sugar.
Thank you for making me smile this morning! You just help set the tone for my day. Headed down to a big orchid nursery and will post what I come back with
