My phalaenopsis has been in flower for quite a while and now it seems to be forming what looks like a new plant on the flower stem! Will it grow if I pot it and what type of soil is best?
Congratulations! With proper care you will have a new plant, identical in every way to your original phalaenopsis. Wait until the new plant has developed a strong little root system of its own, with two or three roots at least one to two inches long. Then, carefully cut the plantlet, called a keiki, from the flower stem and put it in a very small pot of seedling bark for its first potting. After a year or two, move up to medium-sized bark in a four to five inch pot. Alternatively, you can pot the keiki in special orchid sphagnum moss. Be sure to go light with the fertilizer for the first few months. Once the plant has established itself, as evidenced by increased leaf growth, start with full-strength fertilizing.
