Old topic but desperate for help w/ Gardenias Pest!!!
Yep, the ole white fly (I think)...my gardenias are infested w/ those tiny little white spots that go crazy flying around when you touch the bush. I have been to the local nursery...purchased and used several bottles of insecticidal-soap and they didn't budge. Then most recently I soaked the gardenia in a systemic fungicide with no success at all (I had bought the systemic funficide w/ chlorophenoxy?? for some black spots on my river birch trees from aphids I think and it worked well for that). I love gardenias and have them in all corners of my back yard and also a couple in my front landscape. I put two in the trash this morning b/c the white bugs were so bad. Has it gone too far and time to give up on the gardenias or does anybody have an aggressive solution?????
