I bought a beautiful red hibiscus from HD several years ago.
It did very nicely for a few years.
Then, galls began showing up on the leaves.
The condition has gotten worse each year.
The plant looks terrible and doesn't have the energy to produce flowers.
I applied a miticide and removed the infected leaves one season.
That did get rid of them for a short while.
But, they came back with a vengeance.
I just pruned the plant back severely.
If it survives which it may not, what can I do to control these mites without resorting to pesticides?
