Q.Black Spots on Gardenia Leaves and Buds Falling Off

Anonymous added on April 18, 2011 | Answered

The buds are falling off my gardenia bush. It is in full bloom and was doing fine previous to this.  Also, spots have started to appear on the leaves at the same time.

The spots sound like a fungal issue. It probably started because the plant was weakened by a nutrient issue or pests. I would recommend using neem oil. It will treat the fungus with the added bonus of keeping pests away, which gardenias indoors are also prone to.
