                                                          Once established, gardenias do well without watering unless you're in extreme drought conditions. Gardenias don't like full sun- a short period of sun each day is fine but they grow best in semi-shaded areas or full shade. They also like acidic soil, so they'll appreciate being mulched with pine straw or hardwood mulch.
