The semi hydro allows me to water everything at once, making watering schedules simple. It is working for me. YMMV.

Thank you very much for the idea. I have been toying around in my head with the idea of putting my Sharry Baby in semi hidro, but I'm still a little reluctant because of rot risk, let alone with Cattleyas and especially this one. I have never grown Cattleyas before, so this one, a cross between BLC Chia Lin and
Cattleya lueddemanniana, and BC Fuchs Star are my first official attempts (I did inform myself extensively before online, and I'm keeping them in a nice warm room with great great light). Have a good one!

This is a disease of plants kept in hot, humid conditions with poor air circulation. Unfortunately putting it into the bottle and closing with plastic was not the right thing to do.
Go to the Web page of the St Augustine Orchid Society and look at the Pests and Diseases page. Scroll down to
Bacterial Brown Spot - Acidovorax (syn. Pseudomonas)
The growth with the yellow leaf with spots is dead. I think there is a disease spreading through the plant. The treatment is to cut off all affected growths, cutting into healthy tissue. Sanitize your knife with 10% household bleach or 70% alcohol between each cut, and let the blade dry.
Then treat the plant with a disinfectant to kill the bacteria on the outer surface of the plant. The Web page above discusses what to use. |
Hey, that link is so so helpful! Gosh, there's so much I ignore in pests and diseases... Nobody wants to deal with the nasty stuff haha, but you gotta do what you gotta do. I read your comment on my commute and I already sprayed my plant with hydrogen peroxide (searched for physan and it costs about three times more than that fungicide I bought... This plant might end up costing way more than expected, but first I wanna try the basics). Do you think it's a good idea to spray it entirely with hydrogen peroxide daily for, say, a week? Or am I being overly cautious? Should I also preventively spray my Sharry baby who was next to it for about a week? It has no signs (yet) of infection. I moved it apart the same day I took the first pics (november 5th or 6th).
Call me crazy, but when spraying it I didn't see any signs of the yellowing moving further (on the last bulb I was suspicious about), so I'm positive on this. Oh, and I never saw any "water" on the spots, but then I just gave it full attention when it got completely dark.
Thank you very much for your comments, as always. Kind regards!
