Dendrobium anosmum - Orchid Board

My anosmum has 3 old canes covered in keikis. What's the best thing to do with these, pot them individually or put them all into a large community pot? There's probably about 20 of them.

TIA.

If the keikis have roots and are at least 2 inches long, I would plant them individually. I plant my keikis using New Zealand sphagnum in a 2-inch clay pot. If you have some time, take a look at a slide show that I made of Den. anosmum (called honohono in Hawaii). The slide show is 8 minutes long. Here is the link:

As shown on the slide show, I usually cut the old canes when the new growth is about 2-3 inches long on the plant. I store the old canes on a tray and give them water and sunlight until new keikis appear.

i can't believe i didn't mention that my "new" canes are about 24" long. no new growth except for a keikei on one of the old ones. i was wondering whether it was too late to cut off the old ones--sorry!

Although there is no harm in keeping the old canes on the plant, I would remove them for aesthetic purposes. It is not too late to cut off the old canes. The canes may not produce as many keikis if you had done it earlier.
