Yellow Leaves on Gardenia Bushes
I have gardenia bushes, one on the lanai the other outside on patio. Both are potted. The leaves are turning yellow with brown spots on some of them. I have looked for aphids and can't see any. The yellow leaves are falling off but both plants have new growth. One article I read says not to mist, another says to mist. One plant is three years old the other is two years old.
