Oh my yes. The roots only need to be about 2 inches to cut the keiki off. You have far more than that. Both plants will thrive with the split. Just cut it off of the spike with a sterile knife, and pot it in a pot just big enough to fit the roots in.

Thank you for your speedy reply. Couple more questions if I may. (Said I was a newbie) What medium is best for potting into? How much room do they need in a pot when splitting or just re-potting?

Cheers

Sure. They don't need alot of room. I keep on hand a few different sizes of clay pots. When it's time to repot, I pull out the plant, clean off old bark, and place plant into a couple of different pots to see which one fits best. You just want the roots to fit the pot.....no bigger. When phals outgrow their pot, the general rule is one size up.
Now for the tricky part. Everyone has different watering habits and different growing conditions. Due to this we all have differing preferences on types of pots (clay or plastic) and types of growing medium.
Personally I grow mine in clay with half sphagnum moss and half mixture of bark/perlite/charcoal. I live in a very dry environment with low humidity. That is why I add the sphag, for added moisture. Also I can't remember what plants got watered when so when the sphag is crispy....time to water. Sorry so confusing. There is really no easy answer. I hope that helps.
PS. I would repot the mother plant there too. I am not liking the looks of that pot.....is there a drainage hole?

Again, many thanks for your reply, very informative.

The pot the orchid is in at the moment is in fact a small plastic one, with drain holes, that sits inside the larger white one.

it really looks like two keikis(baby plants), doesn't it? does anyone else see that? could you get another pic from a different angle? you may actually have three plants altogether! you have a phal, btw i would go check out the FAQ and get all the info on growing culture. and yes i agree about repotting the mother as well. good luck!

You are absolutely right, there are in fact two parts to the top piece! One of them has actually broken off from the main stem and is only held in place by a twisted root.

It appears I now have three orchids :-)

Wow. Talk about being a mama's boy. Those keikis stuck to their mom even until after they are blooming! lol.

They are more than ready to be separated.
If you want to keep those roots though, you might need to grow them as mounted in cork or in open slat baskets.

How do you managed to keep the roots looking green? Whenever I water my plant, the rots would turn brown and died.

Jumbojimmy, it sounds like you watered too often.

that is a really pretty orchid pic i love keikes that are still attached. you must take great care of it because that is somthing i have never seen before. its amazing...

what kind of orchids are they?

i am 16 years old and i am also a starter. i am trying to grow keikis from a cut spike of an oncidium.

dark_moon, those are Phalaenopsis orchids, and they will often produce keikis on older spikes. Oncidiums, however, do not produce keikis from spikes. If you're going to get keikis from Oncidiums, they generally come from somewhere high up on the pseudobulb and it's usually in response to something your plant isn't liking, like it's new oh so water retentive media, not enough light, etc. Enjoy the flowers on the cut Oncidium spike and then throw away.
