A common cause of bud drop on gardenias is hot, dry weather. The plants drop their buds because they are unable to absorb water fast enough from the soil to replace that lost by the leaves, even if the soil is moist. There's not much you can do about this other than hope for a change in the weather. A rapid drop in temperature can also lead to bud drop, as can infestation with aphids and thrips. Aphids are small pear-shaped insects that can be controlled with insecticidal soap. Thrips are minute black insects that feed on the buds and leaves (which develop silvery streaks). These can also be controlled with insecticidal soap.
