Looks like your surgery on your poor catt will work. I've had episodes of fast moving rots that I just couldn't get ahead of after a dim period of constant rain. Too much rain also gets into the tender new catt growths, causing them to rot.

Can I suggest a remedy to prevent problems: When there's a long rainy period, take any opportunity a lull provides to get out there and sponge up excess water from any crevices with a paper nampkin.

Then spray the orchid all over with a solution of Physan 20. I keep a spray bottle of P-20 around all the time for too-wet emergencies, such as having the plants wet at nightfall, or water in the crown of a phal.

Physan 20 is a contact anti-bacterial/anti-fungal and gives 2-3 days of protection against both bacterial and fungal problems. It's effective against pseudomonas, the fast-moving bacterial rot that causes crown rot in phals, but also can affect catts.

If the rain lasts more than 2-3 days, look for a chance to re-spray.
