Help: Vandas and Dendrobiums never flowered and one not well

[Lilandra]

Hi

Some of my mom's orchids have never flowered and we're not sure what to do with them. If there's anything to make them healthier.

Also, one is not well (she says).

The first she's had 5 years and it never flowered.


The 2nd 4 years.


I'm not sure how long she's had the 3rd.


The 4th she says is not doing well (what does that mean? how would i know?)


Can anyone help? Give advice?

Also, how do people get that nice filmstrip way of showing their pictures?
