Got a great-looking Dendrobium Nobile from a fancy garden center. Thing is, the media looks like potting soil. Normal for this variety of orchid?

Hi Lisa,

Whatever that potting medium used to be, it isn't any longer. Is it currently blooming?

It doesn't really matter what you use to repot your orchid - the only difference in potting mediums is the length of time it takes for them to break down. I normally use a combination of bark, perlite and charcoal. The bark should be small sized because Dendrobiums have small sized roots. Add a handful of perlite (to keep the bark from packing) and a handful of charcoal (to absorb excess salts).

You can buy bark mixes that have all this stuff in them or mix your own.

"It doesn't really matter what you use to repot your orchid" except you shouldn't use potting soil for an epiphytic orchid (which is one that normally lives in trees, not in the ground)

Dendrobiums like lots of air around their roots - as you can see, it's sticking its roots out of the pot to get to the air. So the mix you use should be chunky and airy. It looks really healthy. If it's still blooming, you might want to wait until the flowers are finished to re-pot. Sometimes orchids are divas and drop their flowers if you mess with them.

That pot might be stuffed with moss and the roots are running from it. I'd re-pot in a chunky medium as soon as possible.

Elaine, I made an assumption that Lisa knew we were talking about kinds of bark. Smiling
