More about Cymbidium dayanum backbulbs

Cymbidium dayanum backbulb from last springWhen I saw the progress of the Cymbidium dayanum backbulb that I almost killed due to peeking, I decided to peek some more. I couldn't help it.

When a backbulb or division has no roots it is important to hold it still in the pot. If the pieces are short careful handling may be enough. If the pieces have any height to them, I use a stake.

This pot has a stake in it and from looking at the top, I thought it might be multiple small pieces in the same pot. When I pulled it out of the pot I found that it was all one piece.

About 2/3 of the pot was filled with rockOver potting is always a danger with backbulb propagation. Without roots to extract water, the medium stays wet a very long time. That's why I use rocks in most cases. The rocks hold some moisture without having the backbulb be wet. You can think of it as a variation of sphag-n-bag.

Now that the roots are developed I can pot it. Since this species wants even conditions and comes from a generally wet environment, I potted it back in tightly packed sphagnum moss. It will not get sopping wet and takes a long time to dry out. The general water level can be determined simply by touching the surface.
