Q.Potted hibiscus dying
My hibiscus are dying. The leaves turn yellow then drop off. They are in pots. Watering is not the problem and I feed the Super Bloom. Also, I went to bed and woke up to a plant completely stripped of the leaves and branches. I had that happen last year to two of my plants. I have grown hibiscus for 10 yrs and never experience the problems I am having this year.
