new Dendrobium

[mchhuang]

Got this Dendrobium yesterday- the shop lady told me it's Dendrobium Pak Lai White, any thoughts? The petals have a greenish tone to it than pure white, so I wasn't sure.

Also - I'm planning on repotting after flowers finished blooming.
I was going to use a mixture of bark and LECA.

Any ideas on the ID and timing of the repotting and the media? What do I do with all the roots? How do I tell if I need to cut the roots or if they are good to keep? Other tips?

Thanx! Hope to keep it alive.

It looks beautiful! I would guess it has Den. phalaenopsis related species and antelope/spatulata species in its ancestry. It will like warm temperatures, bright light and regular water all year. There is a good chance it will become much taller, and branch profusely from the base.

With plant like yours I would never unpot and remove old medium. The old roots aren't doing much, anyway, and Dens like this form lots of new roots at the growing point. Just find a pot about 4" / 10cm larger in diameter. Drop your plant, in that pot, into the new pot. Backfill with medium or large bark chunks, depending on how you water.

Most of the time I wouldn't repot any Dendrobium unless it's just forming new root nubs. In this situation, though, dropping into a new pot will not disturb existing roots, so you could do it now.
