I have several Vanda and related plants that are doing fine, including two young plants in a community basket that I've grown from seedlings. The third Vanda in the community basket, purchased from the same grower at the same time, is seriously failing to thrive.

It is alive, but only just. It's tiny - I'd say it has not grown at all in the year I've had it, and just looks frail. The other two have doubled in size and look fine.

Given that the conditions obviously suit Vandas in general, but not this one specifically, what would you do to try to support it?

It's V. Sansai Blue x Manuvadee. I'd really love to see it thrive and grow!

Thank you
