I just re-potted an orchid and used biochar - I expect it may take a while to see what happens, but I have high hopes. I am actually a serial killer of orchids and this is the first one I have managed to keep alive - it has even bloomed several times. I got it from friends when I had my gall bladder out and was in the hospital for 8 days. My friend came to my door with the orchid and had a great big smile on her face. But I froze when I saw it, convinced I would kill it. I have followed friends directions to the T and it has grown so much the roots deformed the inside pot. We shall see what happens.
