It sounds like you did alright! I really don't know what those bumps are. Looks like it is from within the tissue. I would just enjoy the blooms, while keeping an eye on the bumps. If they open or start to spread, then I would cut the spike in a hurry. It may just be some environmental damage. Treating the plant as you mentioned would be OK but I wouldn't spray the blooms as it might ruin them.

I like to grow my Cym's outdoors after any risk of frost is past. They get a fair bit of sun and I feed them quite well over summer. Then I bring them in just before we get freezing nighttime temps. The cold chill seems to encourage the spikes.

Your Den is very nice too.

Thanks silken, So far the bumps have not change. So I'm hoping is just something environment too.
I will just keep an eye on it.

I do keep all my cym's outdoors, thankfully I'm in a area were the weather is great for them. Most of my orchids are outdoors for I have indoor cats and so in order for me not to want to kill them, most of my collection and any new additions have to be able to stay out doors for most of the year. So far so good!

I have 3 indoor cats. Two leave plants alone but one chews the leaves on any of the Oncidium or grassy leafed types. I do grow in a greenhouse but if I want to enjoy blooms in the house on some of these, I need to dip the leaf tips in olive oil and then in cayenne pepper or he will demolish them. Such a little pain in the butt

Hopefully it will be nothing, good luck they are beautiful. Silken have you ever grown cat nip for him? I wonder if it would make him leave the orchids alone.

Two of my cats love to chew on orchids. One only likes den. nobile leafs, the other one any long grassy looking cym or onc. When they are not nibbling, they like to play "lets turn the pots over"! The rest could care less.

I have grown their own wheat grass and they like that, but then they still want to play with turning the plants over so they can play with the media.

No-Pro-mwa, we have thought of grass, but it (and orchid leaves) makes him puke and I would rather not encourage that!

OK, now this, I can understand.

Just an update: No changes on the buds, and what ever it is, does not seem to be spreading to the rest of the plant. It still isolated and will continue to monitor, let you know if I find out what it is.

So far I'm

and keeping finger cross.

So I think I found out what this bumps are. Yesterday I run into a friend who is a member of the CA orchid society and she had lots of orchid plants in her car (They are having a mother's day weekend orchid show and sale and she is helping select some of the orchids for the show) , and one of the cyms she had was afflicted with the same type of bumps. So I ask if she knew what that was and she told me that although it looks bad is actually environmental. She said is part of increasing humidity too quickly, specially if the older pbulbs are declining do to age. She said is a condition called oedema and it occurs when roots take up moisture faster than it is lost by the leaves through evaporation, the excess moisture can cause the plant's leaves and sometimes the buds to swell and develop blisters that them become hard or corky bumps. She said that if the plant is not in bud when this happens it show up only on the leaves, but because some cym loose leaves on the older pbulbs they don't have many leaves to help with evaporation and if the plant is in bud it will appear on the spike and on the buds.
She also said that they remain in the plant until the leaves die or the flowers fade, but that is not harmful to the plant.

What do you think, has any one ever heard of oedema?

silken · #20 04-22-2015, 07:04 PM

Yes, for sure and oedema does appear as bumps on leaves, caused by too much moisture. So I could see it being in the blooms. Never heard of it in blooms before, but it is part of the plant so I think it could happen. And if its not spreading, it explains a few things. The lady who sold them did mention it was from rain so now it makes more sense.
