Leaf sheats getting glassy (and mushy) => spreading to plants

[Lars Kurth]

Don't have a picture of an affected Sarong, but you can see how the Sarongs have grown larger than the pseudobulb. When the bulb comes out, the top of the Saron opens and water can get trapped between bulb and sarong.

Also when the sarongs become yellow, some do not dry but become glassy and mushy.
