Two of my spider plants have the brown discs mentioned. I assume it is scale. I have been removing the discs by hand but when I find a stalk with numerous discs I remove it and try to save the babies if they are unaffected. While I have been diligent at this, they still come back. I even washed the plant with mild soap and water as I read it is a way to get rid of scale. It still comes back. Any ideas?
