I find that my hibiscus like to be left in one place and not moved frequently. I have several different varieties and colors and some are pretty big but i still ahve them in pots. I have grouped them outside along the fence with the appropriate amount of sun and shade and I find they do better when not moved as much. When i have had to move them or repot that is when they don't produce
flowers and even the leaves react. I have one that is a peach color and it is very particular. This year it only has flowered once and that was after having been in the same place for 9 months. Since I moved it to its present location it has refused to
flower. All the others have flowered but this one is being stubborn. Hope this helps
