Des, Would love to see a picture of the Disa cornuta if you have one. At least your son is interested in orchids mine is interested in tomatoes. At least after a day in a chemistry lab he moves dirt in the garden. Its good for him. Saving samples of our species and habitats is of interest to me but just a side interest. I wish I had more time for it. Was working in Connecticut years ago and a species of Lady Slipper was located which had been believed to be extinct. It was extinct soon afterward - people found out about the location and trampled them all to death.

ORCHIDS3- I can't lay my hands on a pic right now as a power spike blew my hard drive a few weeks ago and I lost all the pics i had taken over the last few months , that has taught me a lesson and some . I had also just about completed a presentation I am to give at our orchid society meeting in March So i have to start all over again . But not to worry I will find one and send it to you along with a pic of Satyrium Coriifolium which is also grows here

Thanks for the WOC pictures. It is interesting to see the flowers chosen by the different people taking the pictures. Yours was the first one with so many cymbs. THANKS

Hi,

I also have cymbidiums and they are turning yellow at the base. I was given them as a gift and repotted them about 8 months ago.

Glad you found us.

Do the pbulbs feel soft at all ? It's hard to tell from the pix - are the pbulbs buried? or just not developed? If buried, pull them up. Shouldn't be more than just a bit of the bottom of the pbulb buried in the potting media - I usually leave mine just above the media. I'd also recommend considerably smaller pots.

Hi Sonya,

thanks for the welcome, i am glad I found you as well.

I will check them when i get back home from work and also raise the bbulbs from the growing medium. Is it fine if i transfer them to smaller pots now? I am in South Africa and we are going into winter here.

Thanks

Devraj

Yes, raise the psuedobulbs so that just a bit at the bottom is in the media. I hope they are ok after having been buried in the media - that could be the cause of the yellowing. The p-bulbs should (hopefully) be firm. After getting the p-bulbs out of the media, I think that the pots they are in may be ok size-wise. I wasn't picturing that in my head.

If you need more help, or have other questions, let us know. You can go ahead and start a new thread/topic - will help you get more people looking at, and hopefully replying.
