Black spots on Dendrobium lindleyi leaves
 

Hi all!

Recently received a Dendrobium lindleyi through the mail. It came to me with some black spots on the leaves but otherwise the roots and everything looked healthy. Is this just from the trauma of being shipped or something more serious?

That's old damage. It could have been from bugs. It will not harm the plant. Watch the plant for bugs.

I personally would not worry about the spots on the leaves but the colour of those bulbs/canes would make me send the plant back.
They are brown and about to die, not just one of them, looks like 2 bulbs on the left will stay unaffected. The plant can survive losing all those bulbs so it's up to you. I can't really see how many healthy bulbs will be left once the brown ones completely dry out.

edit: ah I didn't see the good bulbs on the next pictures, like said the brown ones will dry up - if they go rotten, twist them off the plant but you have plenty of healthy bulbs for the plant to carry on

Dendrobiums are quite hardy and can lose a few canes but I would check the rootzone that there is nothing left rotting in the pot which might be causing some bulbs/canes above to go bad.

The leaves look just fine. The concern is definitely with the colour of the bulbs. Very gently ----- (gently) squeeze one of those off-colour olive/brown bulbs with thumb and fore-finger on one hand. If very hard and dry - maybe ok. But if soft/mushy ------- then that would not be a good sign.

Den. lindleyi pseudobulbs shrivel and brown like that as they age. No worries there. The plant looks fine (or as fine as those things ever do...) They can bloom from seemingly dead-looking pseudobulbs... from the base, or the side. Important to give a dry rest in winter, to give yourself a fighting chance of getting flowers in the spring. (It used to be called Den aggregatum... a lot of people call it Den. aggravatum... they can be frustrating, but beautiful when they do bloom)
