Oncidium stacyi

Some (hugely) limited experience.

Hi Ed,

My brother deflasked a bottle of these guys about two months ago (late spring/early summer in Sydney) and all the plants he gave me (about 8) are all doing very fine. His plants are generally stuffed but that’s because a bug came to dinner so a few of mine will head back to him shortly.

All the plants have put out roots. They are mounted on either cork, bark and black tree fern. All are positioned high and bright and get watered once a day at the present.

Min temps are 18c-19c at present with temps getting to 35c-40c (occasionally). Once it cools, I suspect the watering may reduce however even the winter days get warm in the glasshouse and given the type of mount I have mine on, watering will probably remain regular.

When I mounted, I put a tiny bit of spag moss at the base of the seedlings which didn’t, as far as I could remember, have any/much root ex flask. The roots seem to be growing outside of the spag though it may be more accurate (?) to say there may be roots under the spag but there are definitely roots outside of it. All are putting out new growth.

My brother took a picture of a fantastic plant in the Singapore Botanic Gardens. Long way to go ….

Good luck!

 

Hi, if the growers of these plants are still about - what were the minimum temperatures that were managed, I read they're warm growers but many warm Oncidiums seemed to cope with cooler temps as well. Just thought I'd ask what the experience was in Winter, especially for seedlings. Thanks

 

Hi. I have an unbloomed stacyi, which I have been growing for a couple of year mounted. Mine takes temperatures between 15-16c(60F) in the winter, and it does not skip a beat.

 

I have 2 big plants. In summer both had flowers. It was mounted on baskets filled with bark and stone wool. They are hanging at a door. The longest leave is 2 meters

 

In Europe it is important to hanging the plants in Fan current. It must alltime dry very fastly
