Yellowing leaves

Yellowing leaves, especially lower down on the plant and from the inner parts of the branches is normal this time of year. Your plant is shedding older leaves in preparation for developing healthy new leaves. If the plant is yellowing all over, you may be overwatering. Gardenias like lots of water, but the soil should drain well. If it remains soggy, it can actually suffocate the roots so be sure to allow the top half inch of soil to dry out between waterings. Gardenias are finicky, and any change of location or humidity or sun can set them back. Spider mites can also cause yellowing leaves and flower bud distortion. Look on the undersides of the leaves for tiny black specks and whitish webbing. If you find the mites, use insecticidal soap or a neem-based insecticide to control them. Best wishes with your gardenia!
