Second new growth on Cattlianthe Jewel Box

Cattlianthe Jewel Box 'Scheherezade'

     In addition to the nearly mature pseudobulb, and the new growth I recorded one month ago, there is a third pseudobulb that is just starting out.

First sign of new pseudobulb on cattleya

     In other less welcome news, I cut off one of the leaves, because it developed some suspicious spotting at the leaf's base.  Whatever it was, it didn't look like light damage or physical damage, and I didn't want to risk it spreading further.

Suspicious leaf damage

     None of the other leaves have similar damage, and I'll be checking regularly to make sure they stay clean.  Since I don't want to keep using the same fungicide at the risk of breeding resistant fungal strains, I ordered some physan.  This way, if I want treat a plant, I won't be using the same kind of chemical on it over and over again.

     I should probably also wipe down and disinfect my growing area.  I'm not sure when I'll get around to that though.
