How to rid large, old gardenia bushes of sooty mold. Moved into old home with well established yard on the marsh. Gardenias (near marsh) are heavily infested with scale & sooty mold. Have read numerous articles re: neem oil, washing, etc., but concerned bushes may be "too far gone." Bushes have not been treated, but continue to produce new growth. Ok to cut way back - similar to old azaleas? Open for all suggestions as would hate to lose them.
Neem Oil is organic and safe for people, pets and bees.
Treat the plant and then repeat weekly until you see improvement.
Pruning in late summer is fine for your plant. Waiting until the plant begins to improve from the fungus issue, will help reduce the stress when you prune.
Prune no more then 1/3 this summer.

Just a put a new gardinia plant next to an existing gardinia plant (which is doing well for 2 years), new plant lost most of its leaves, has small buds that bloomed very small flower, is something wrong with soil?
Your plant is likely shocked from the location change and planting.
Gardenia are very finicky and do not adjust quickly to transplant.
Make sure your are watering the newly planted Gardenia and that the soil is moist but well draining.

I planted three frost proof gardenias about a month ago and have noticed that the leaves are yellowing with a few having dropped off. Although not under the canopy of the black walnut tree, they are within its root system. Are gardenias sensitive to the toxicity produced by these trees?
Since Gardenias are known to be finicky, the Black Walnut Trees likely have nothing to do with the yellowing leaves.
Gardenias are not on the list of plants sensitive to juglone.

Yellowing leaves are likely related to watering issues or nutrient problems.

I live in Florida, just north of Clearwater, Fl and I was told to buy a grafter Gardenia which started with the letter "D", but I can't remember the name.
There are about 200 varieties of Gardenias.
I found one variety named 'Daisy'.

I have these pesky little black and in my Gardenia tree its a Topiary... I recently had to move it and that's when the ants got in it .... it did have aphids and mealy bugs but i got them off ..I had to recently put some of that Diatomaceous Earth in the dirt and on the plant ..and I also had to spray a insecticide on it to kill most of the ants .. All of my bloom have fallen off :( it was full early this summer and still has maybe 1 or 2 blooms left.. I had to deadhead the old ones and in the bottom of the flowers had lots of ants, i guess because it has the sweet stuff in the flowers... Now my question is , are the ants cutting the blooms or is it because of the move,,? I will have to move it 1 more time and that's when i move.. Should i just prune it back and forget about this season or what ? Thank you Nikki
Gardenia are finicky plants so the answer is both have likely stressed the plant.
I've listed several articles to refresh you on the care requirements and information on how to get your plant back to health.
