Phalaenopsis will generally rebloom given a little extra care. The spike should be cut between the scar where the first flower was and the last node on the stem. One of the lower nodes will then initiate and generally produce flowers within eight to 12 weeks. Younger or weaker plants may not rebloom. It is also a good idea to cut the spike off entirely by midsummer to allow the plant to grow for next year's bloom.
Many homes have insufficient light levels for the reflowering of most orchids.
However, there are a few orchids that prefer lower light and will reflower under home light conditions. Home light means light provided by a slightly shaded south window, or an east or west window. These plants will grow easily under the same conditions enjoyed by African violets. Another good choice, but usually only for those already initiated in orchid appreciation, are the paphiopedilums or lady's-slipper orchids. These, like phalaenopsis, have relatively attractive foliage, and will reflower in home conditions giving weeks of floral display.
