Question
i have many vandas one of which is about 8 years old.  I has 3 blooms stems ready to open.  It appears the are two new plants growing off the main stem in the center where leaves as attached just above the roots.  The roots a over 4 feet long.  Is it possible these are new plants?

If so how do i remove and pot new ones.

Thank you for you time and assistance

Answer
Dee, it is not unusual for vandas to produce keikis (ie new plants) that can be removed and potted up separately.  This is best done when there is new root growth on these new plants. While these are part of the mother plant and can be left on indefinitely, with healthy roots of their own, they can also, when separated from the mother plant and potted up separately, continue to grow and produce new growth.  I try to "harvest" one keiki each year from my large 20 plus year plant and have had good success in growing and flowering these.  This provides insurance against the potential loss of the mother plant at some future time. I try to use large plastic pots with lots of treee fern in the pot to help anchor the new plant, provide an airy environment in the root zone, and reduce the potential for root damage during the potting process.  I have not tried to tie the keiki bare root into a basket which also would probably work if the environment is humid enough.
