Spotted Dend. leaves

[Sarahbelle]

Pretty new to raising orchids and have 2 dend. right next to each other in a West facing window.
I water once or twice a week (4-5 days).
One looks perfect, should bloom in a week or two.
The other I purchased at a Home Depot about a year ago. It sent up a stem last fall/winter and was looking good and then it just stopped.
It sent up another stem recently and seems to be doing alright, but the new stem is developing black spots on the leaves. They are indented in the leaf.
This one is growing in a tree stem instead of bark chips (like the other) so I'm not sure how to repot or if it's needed?
Any tips?

If it is a mounted plant that you are having trouble with, maybe it is not your usual Den. Any name on the tag? A picture of the spots might help. If you are misting, are you doing it early enough in the day, so that the leaves are dry by the time the temp starts to fall?

the growing medium sounds like coconut hunks which I do not like.

when you get a chance re-pot it

Den leaves are always a frustration. I seldom get more than a year out of old leaves except on my oldest plants. some black spots are not something to worry about unless they are expanding.

There is a lot of fungal rot this time of year in areas of heavy rain like Florida. this rot will grow larger on the leaves and should be cut off.

Sarah, you might want to up date your profile with your location. Even growing in a home will be very different for people in very different climates.
