Onc. Lava Burst "Puanani" growth stop?

[Sekhmet]

Hey All,

I have a ~4 year old Onc. Lava Burst that has three growths, has flowered 3 times since I purchased it 3 years ago, and has completely ceased to do anything!

The leaves are a bright, light green, roots seem to be fine, but there has been no new growths, no flowering, nothing!

I really like this hybrid and would love to spend the time growing it up to specimen size, but obviously that isn't going to happen with a total lack of growth!

I water weekly with a weak fertilizer, soaking for 15 minutes. It is in a west facing window, but that hardly matters in Seattle this time of year...

If you haven't change anything, light, fertilizer, watering. then maybe it's time to repot. Might encourage it to start growing again, but I'd wait till Spring. Is it in bark chip? Oncidiums seem to like bark chip because their roots are so fine.

I'm thinking along the same lines as Carol. When was the last time this orchid got into some new media? What is the current media?

Extra lighting during the dull days of winter can help any plant with slowed growth. Perhaps a CFL is needed.
I have found onciduims grow well in just about anything with good moisture with good drainage thru-out the media.
