Hi, just me again. I'll drive you bonkers with my questions, but I want to make sure I know as much as I can about my plants. I have a commercial Oncidium, tiny yellow dancing dolls, I'm not sure the exact name. Anyhow, It lost it's flowers so I was about to chop off the spikes. Looking closely, it looks at though there is new regrowth where old nodes are. Is this typical of this flower?
Ok, that was me going bonkers....
Just kidding... Your questions are great. I hope other folks reading this are gaining something: they're good questions.
I personally have never seen an Oncidium rebloom on an old spike. Which is not to say it could never happen, it's just to say that I personally have never experienced that. What I think you're probably seeing is the leftover green / clear tissue that suported the old blooms, and if you waited another week or two, you'd find the entire spike begining to die down from the top.
On all of our Oncidiums and the Intergenerics bred through them, when the blooms start to go, we just take a new razor blade and lop the spike off altogether so that the plant doesn't expend energy keeping a last little flower alive when it could be growing something new. That's what I'd recommend doing.
BUT: can you get close enough to the spike with a camera to post a pic? If I could see what you were talking about I'd be able to tell you more for sure. If it is actually reblooming from the old spike, that would be a novel thing (for me anyways... I may have been clueless all this time (!!! ) Hope that helped some....
lol, nice bonkers face.
I'd take a pic of it, but it is at my boyfriends house. Now that you say it could be from where the flowers were attached, it makes sense. I pulled back some of the clearish tissue and there looked like new growth. I don't have a photo of it though. I think I will be going over in the next few days to cut the spikes off.
Thanks for all the answers, you are helping me so much in my pursuit of Orchid growing.
