Phalaenopsis post bloom and Dendrobium 'Chiomy' problem

[tree1]

Phalanopsis - This has been in bloom for months and just lost its flowers. What do I do now? You can see the spikes have tuned off colour. Should I cut these off and where abouts should I make the cut?

It also has a new spike at the bottom poking through.


Dendrobium - this was in full bloom when I bought it, it began to lose it's flowers about a month ago (I assumed this was just natural) and now it has slowly started to lose leaves. they turn yellow and then fall off as you can see.

The plant also has lots of new stems. The leaves are badly developed and folded over.

Do I need to cut the old ones down?

I'll speak for the Phals, the Den I'm not quite sure about.
The Phal spikes, once they've gone/or going brown should be cut off, as it's now dead/dying. That said it is personal preference whether to cut the whole spike, or just the dead portion. If you only cut the dead portion above a live node, then you could get a side branch of new flowers (as you have in Pic 1). But these tend to be smaller, in my experience, than those from a new spike (Yet flowers are flowers right?).
Cutting the whole spike generally helps the plant focus on growth, yielding, generally, better flowers on the next new spike (but you have to wait on them).
So, like I suggested, it's a choice you have to make, and either way, the plant will probably be just fine. If the plant is struggling in ANY way, I would cut the whole spike, otherwise, keep up the good work

RE: Den

You may trim off the dead leaves, leave the canes. Healthy looking plants you have.

the den looks like it's possibly a deciduous one - one of mine is dropping leaves from the older cane now. In my experience, many dens drop leaves after repotting too, so if you recently did that, that could also be a cause.

Hard to tell on your pic - in what way are the leaves "badly developed and folder over"? From what I can tell, they look ok ... This plant probably doesn't want the media to dry out completely - if it's one that wants a winter rest, then it can be dry in winter, but this time of year, will want to remain moist - too dry could cause foliage to come in crimped, preventing subsequent foliage from developing properly also

Thank you very much for the replies

I think I may have been under watering the Den based on what you've said, White Rabbit. If I begin watering correctly will it 'recover', or have I started a chain of events?

Also do you think it needs re-potting? Should I hold the new growth up with stakes?

[WhiteRabbit]

I'm not seeing anything to be concerned about - but maybe I'm just not seeing it

if it has been underwatered, increasing the water should help, but if the foliage coming in at the tips is very crimped, you may have to help open them up, for the new foliage to 'break out'

it's never a bad idea to repot, if you don't know how old the media is

you can stake the new growth if you like, and it makes life easier - I have one den that wants to grow pendulously, and I have been staking the canes, since it grows on a windowsill

You can choose to prop the canes up or leave them be.

Depending on the heritage of your Dendrobium hybrid, it may contain the genes of a sprawling species, idk.

The leaves on the Den. curling are a result of under watering just a bit. Watering them a bit more will not make them straighten out. It will make the newer leaves grow more normally though.

I don't think this Dendrobium goes fully deciduous. It may be one that only goes semi-deciduous, again idk, because I don't know it's heritage.
