Gardenia Diagnosis

Question

I grew up with Gardenia bushes and now appreciate my mother’s efforts. I planted two gardenias in very large pots on the north side of our home (Fort Worth, Texas) the summer of 2008. They get sunshine but not too much, as we have pecans that shade them. This summer they flourished as I fed and watered them regularly. Now they are very, very unhappy. One has some yellow leaves and the other droops like it has not been watered in years. Help!!!

Answer 1

Yellow leaves on gardenias can be caused by several things. This article will help you with that:
