Gardening advice

Hi 🙂

I have a row of gardenias and they have been there for about 14 years but just recently the leaves have started to change white.

Can anyone help?

TIA

I suspect the white patches are powdery mildew and the white leaves is from overwatering.

Powdery mildew looks like a white powder:

mealy bugs are bugs, and they are white and fluffy:

I would give the gardenias good feed of something specific for acid soil loving plants, and hose off the white stuff.

Crystal, I seem to remember you mentioned in a previous post that the gardenias  were dividing 2 driveways.  Is is possible a car being washed in the vicinity is creating this problem?  Car Wash Shampoo?

I have a similar thing happening with some of my potted plants

Gosh, it looks like someone has shaken a nearly-cleaned painbrush around.  

Interesting.

clever girl, these pots are next to the tap we're using to clean the paint bucket,  brushes etc.

Guess how I know that it can look like that.  

Seen it done hereabouts.
