| can the black spot wipe off with your hand? may be just mold. Where this orchids come
from? If it come from the North(like minnesota somewhere like that.)
If it is mold or fungus, you need to starve the fungus of water for 2 or 3 days before
watering.
If the black ring on the stem cannot come off, I saw this quite a lot in Vanda. I usually
throw them away. (i hope i am wrong). Look like some type of rotting. Separately this
from your collection of orchids just in case. |
