Q I bought a Doritaenopsis Sinica Prince with one spike bearing six to eight flowers. Soon after the flowers were finished, what I discovered to be a keiki appeared at the end of the spike. It has grown quickly, and now it has two small leaves and some small roots. What do I do with the keiki?

A  You have hit the jackpot — flowers and a free plant. You can either leave the keiki and let it develop to where the roots are at least 2 inches long or you can get some damp sphagnum moss and place this around the developing roots and enclose the mass in some plastic kitchen wrap. This will encourage the roots' development — especially if you regularly trickle some water down the old flower stem and keep the moss moist. When the leaves and roots have grown to about twice their present length, cut off about an inch of the old stem attached to the keiki and pot in orchid mix in a small pot. Within approximately a year you will have a plant large enough to bloom and an exact copy of the original. —Andy Easton.
