Hi, Imaeus! You might want to put something in your profile about where you are. So much of gardening is climate/location-based. Generally though, plant Gardenia is a very sunny spot. Unless there's drought, it shouldn't need supplemental watering after the first summer. I've never fertilized the shrub in our yard, just keep the base mulched. It blooms well. This is a weird shrub that can make an occasional flower at any time of year, but there's a main flush of them in early summer.
...or are you planning to keep it in a pot?
