Answer: Gardenia's can be temperamental, and are reluctant to bloom unless given perfect conditions. They thrive in full sun with filtered afternoon shade, warm air, moist soil with good drainage, and morning dew or misting from the hose. Use peatmoss as a soil amendment, plant the crowns high, don't overcrowd, and feed every 3-4 weeks with an acid based plant food or with fish emulsion. If you can accomplish all the above, your gardenia's will reward you with lots of fragrant blooms.
The plants can be started from seed. Sow 1/8" deep in moistened seed starting mix with some fresh peat added, cover pots or trays with plastic wrap to help retain moisture, and place in a warm area such as on top of the refrigerator. Seeds will germinate in 25-30 days when kept at 65F-75F degrees.
