Questions About My First Cattleya Sheath

donna_cOctober 29, 2010

I just noticed a sheath containing buds coming up on my Blc. Mahina Yahiro Ulii. I'm thrilled because I've had several cattleyas for years but they've never bloomed. I added additional lighting above them and I'm hoping that the others will bloom too.

How long does it take for a cattleya to go from new sheath to blooming? Is there anything that I should or shouldn't do to the plant at this time? The plant is huge, but has only one sheath. Will that likely be the only one, or do others form in succession?

Thanks, Donna

The answer depends on whether your orchid normally blooms in Autumn or Winter or Spring. The sheath may go grey and appear dead while the plant waits for the appropriate time to flower. No peeking because you may damage the developing buds.

Normal growth pattern where your conditions simulate a bit of winter is for the plant to "rest" during winter and start to grow new pseudobulbs in spring.

There are some where the process is quick and there are some where the sheath forms and sits for a whole year before blooming.
