Question:

How do I care for a potted flowering gardenia purchased at the florist?

Answer:

Place gardenia in a brightly lit, cool location.  The location should receive bright light, but not direct sunlight.  Ideal temperatures are 55 to 65°F during the night and 65 to 75°F during the day.  Check the potting soil moisture frequently.  When the surface of the potting soil becomes dry, promptly water plants. Do not allow plants to dry out or sit in sleeves full of water for extended periods of time.  Plants are prone to whiteflies.  Monitor frequently for these pests and treat them as soon as they are noticed.

After the flowers dry and shrivel, discard the plants. Gardenia is not winter hardy in Iowa and is very difficult to get to rebloom in the home.
