den. health question...

Hello gang!
This dendrobium has developed some nasty looking spots on some of it's leaves.
What should I do, and not do?
Thanks!

If it is dry or dried up, and not spreading - then no need to do anything.

Just maintain nice growing temperature, and a safe level of lighting (not too bright unless the orchid has been sun-hardened ...... but even sun-hardened will have upper limits), and nice gentle air-movement.

The spots are dry - and don't appear to be spreading.
So I think I'll take the "no need to do anything" advice to heart.
Thanks very much

Most welcome Karl. From the appearance of the orchid from the photo ------ it certainly appears dry at those patch regions. Your orchid looks just fine.

Do you, by any chance, mist your plants when they might be in direct light?

I've caused damage like that with "lensing" water.
