Pests & Diseases

Having problems with your orchids really sucks… here are a few good links to websites that helps you diagnose and deal with it. More to come as I find new cool resources. Let me know if any of these links have gone bad over time. If you have any other good resources on the subject, please let me know and I will be happy to add them to the list.

Remedies
Nematode warfare!! Predatory mites that take out the evil guys… no poison necessary (I buy mine from Lindesro) First Ray’s Home-Made Remedies and Treatments Jose Luiz’s personal organic recipe against plagues (insects etc) House plant pest control (wvu.edu) Physan. Many problems we encounter calls for the use of a flungicide called “Physan”. We cannot get a hold of this in Sweden, but according to Ray at firstrays.com you can use a weak chlorine solution as a substitute for Physan (1,5 tsp/liter). I have found it to be quite effective and harmless to the plants. Light white mold on surface of the substrate, spray a solution of Atamon (preservative used when making jams/pickling), 1-2 teaspoons to 1 liter water.
