An Orchid plant should not be a one time, enjoy while it last and out the window gift.  It's not like a flower bouquet, or a rose flower arrangement, it's an orchid plant!!  The best rewards usually come in the following years where they can extend to give off multiple stems with multiple shoots and many flower buds. 

Caring for the plant is fairly simple for a Phalaenopsis or Moth Orchid like this one.  After the orchid looses it's last flower, cut the stem at about an inch from the base of the plant.  Seal the cut area on the plant with a little cinnamon and place in a less lighted area in the house or if outdoors where it gets weak light.  Keep watering it as usual, about 2 to 3 ounces once per week, in the summer twice per week.  Do not over water! If uncertain if it needs water, don't water.  Orchids prefer to go pretty dry before re-watering.

Clean the leaves, enjoy it's growth and within a few months you should start to see a new stem imerging, maybe 2.  Start fertilizing at this point every 2 weeks and move plant to a better lighted area.  Never in direct sunlight.  In about 8 to 10 months after you cut the stem you should be rewarded for your well earned efforts!!

Enjoy Orchiding...
