Dear Orchid Doctor

With Betty Ashley

Saturday, October 29, 2016



 


Dear Orchid Doc:




With all this rain, we go from one extreme to the other.


Please tell us how to treat the orchids in this extremely wet weather.




Marjorie from St Ann





Dear Marjorie:


Thank you for your letter. People are telling me that I have basically covered all their questions, so there is no need to write.




Remember that too much water is the enemy of orchids; they will get a fungus and drop dead almost overnight.




Some fungi are more deadly than others, so you will need to spray with a fungicide/bactericide/algicide.


With this amount of rain I use Physan once per week, and in between I use another like Ridomil.


So technically I am using two different fungicides twice per week, as in my area it rains every day.







Dear Orchid Doc:


With this amount of rain I have been seeing a lot of powdery-looking little dots on the roots of my orchids.


What are they, and how do I get rid of them?




Ruby





Dear Ruby:




What you are seeing is the embryonic stage of a fungus.




This is how a fungus starts, and if you look carefully you’ll see that it is on a dried piece of the orchid’s ‘skin’.




Please take off the dried parts as these harbour the fungus.




If it is still in this stage, use some diluted 50 /50 water with some rubbing alcohol on a cotton ball and wipe away the evidence of the fungus, after which you should rub a powdered fungicide like Ridomil on the affected areas.


If you can isolate the plant and protect it from the rains, that would be good.
