Orchids with only bulbs, no leaf left- rescue?

[Helene]

Well, my phalaenopsis are doing great, but I have some other orchids that had a rough winter. (I was not able to take care of them)

Have some different species-
Dendrobium hibiki, only roots left... Guess that one is gone?

Coelogyne- only bulbs left, no leaves- do they tend to bounce back?

Pholidota imbricata- one big leaf left on the newest bulb, so this one might survive

Zygopetalum Louisendorf- making a new growth from the newest bulb, no leaf left

Lycaste aromatica- this is supposed to lose leaf I believe, but the newest bulb is not the same shape or color as old ones, kinda look sick. Should I remove it, or leave it? Will old bulbs make new bulbs if the newest are removed?

They have been left without water for a pretty long time, so the damage are caused by wilting. Except for the lycaste, seems like it may have gotten molded on the new bulb.

Any advice? I have not repotted, just started taking care of them, maybe I should repot and check for damage on roots.
Are they fussy about this, or will they most likely bounce back if I just give them time and proper care?

Can add picture later if that might help

Plants with pseudobulbs can sprout new growths from the short rhizome at their bases. Keep them warm and humid, and time will tell.

If that lycaste is a sickly yellowish green color, don't worry. That's pretty common.

Yeah, it is- the rest is dark green- the new one is yellow/green, and is long and thin- not short and thick.



The mix is great- greenmix- but: grows nice and lovely moss on top (its a mix of perlite and well- some isolationstuff), but of course- that decayed and turned like soil when I didnt water (about 2mm on the top)
Same goes for all those mentioned in first post.

What I would do is water them each and keep a eye on them all for any signs of new growth. Its sounds like they also went dormant for a short time. The one in the picture I would soak for a few hours and then let drain. Giving the bulbs time to absorb as much water as possible.

Don't give up. It is amazing how orchids with pseudobulbs can come back from drying out.

I agree with this post. I like to think of orchids like I think of periennals - if the roots are still alive, there is a good chance the vegetation can grow back. Just remember that without any foliage, their ability to transpire (take up and release water and air) is very restricted, so they won't need much water. Don't overwater
