I am sorry for this delayed reply to your gardening question. The spring rush has brought a deluge of questions and we are working hard to catch up!
Gardenia needs some morning sun but not necessarily all day sun. Afternoon shade is good too. If the blooms died it may be due to flower diseases which love rainy weather. Avoid wetting the flowers and foliage when you water after the plant is established well it should bloom again and be fine.
Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
