Hi,
My phal seems to have bacterial brown rot : It developed a soft brown area on a leaf, which I removed and applied cinnamon to along the cut edges. I now see another area on that remaining leaf. I cut that away with a razor which I discarded. What to do??
The bottle of physan 20 says for orchids to add 2 tsp. per gallon for a spray. The article here on pests and diseases says 12 tablespoons per gallon!!!!!!!!!!
Which is correct? What should I do to save my orchid?
Thanks. for any help you can provide
