[AG] Gardenia questions

[Samuel F. Rowen]

I live in the city of Philadelphia, PA and have a large gardenia plant in a
large planter inside the house.  I realize it needs special care re the
temperature and watering.  I bought it about 3 weeks ago.  Since then it
has had 3-4 blooms.  However, the leaves are turning yellow and falling
off.  I keep the soil moist but not wet/soggy.  It does not get any direct
sun or sun light.  The questions I have, is why are the leaves turning
yellow?  Can I take the plant outside on the deck?  Can I leave it out
there all winter?  Can it take direct sun?  I would appreciate your
expertise very much.  Thanks.  Ruth Rowen
