I planted hibiscus in my yard last summer. I am having 2 problems. One is that the plants that aren't getting enough shade (i am assuming that is the problem?) are not growing very well and they are really "thin". You can see what I am talking about in the middle and right picture. I planted the hibiscus so they would grow tall and hide the fence but that isnt happening. Any advice? If you dont think hibiscus will work for what I am trying to accomplish do you have any suggestions?

The 2nd problem is related to the hibiscus I have that are doing well. The problem with those is that many of the branches are "floppy" and falling to the ground, when I wish they would grow upwards. Should I provide support somehow to make this happen? You can see what I am talking about in the far left picture.

I have no prior experience gardening, and appreciate your advice!
