Half of our Rose of Sharon Tree is dead. The trunk appears split down the middle which has left one side full and beautiful and the other side stark although there is new growth below the barren branches. The tree is starting to become lopsided and will quite possible split further. We know we need to cut down the tree, but are not sure where and how to do this, so it has a chance of survival. Any recommendations?
You can cut this thing back to the ground completely, and it will still come back with a vengeance. If you would like, you can just take out the dying growth and leave what is still alive.

I have a border of Rose of Sharon bushes a few have the leaves turned yellow with the brown specs. They also are becoming very thin. What can I do ?
This is often a sign of a soil born infection. The best and easiest remedy from here will be to apply dolomitic lime and wettable sulfur together over the area. This will kill off the infection, and recondition the soil pH to a proper condition.

Is it possible to cut it back would that make the new branches go up and out desperate for help to save my mom's shrub if she is no longer with me
This can happen as a shrub ages. Fortunately, this one is very forgiving to extreme pruning. In fact, it will likely help to restore this to a better flowering condition.

Took some cuttings early this year they have rooted but when do l plant them
It is best to transplant these in spring. If there is any way you could keep these indoors until then... That would be best. Here is an article on their care: https://www.gardeningknowhow.com/ornamental/flowers/hibiscus/how-to-care-for-hibiscus-plants.htm
I have a rose of Sharon which was a small tree (not a bush) when I moved in to my home 26 years ago. it has been pruned back many times including a hard prune last year. in (hard) pruning this year I noticed there is lichen growing on the trunk and branches. also there seems to be some spots on some of the leaves. what should I do to save my beloved "tree"?
Lichen is normally not considered a pathogenic or parasitic condition.

It is perfectly fine to prune rose of Sharon anytime while it is dormant. It blooms on new wood so you won't be sacrificing or cutting off summer blooms. https://www.gardeningknowhow.com/ornamental/shrubs/rose-of-sharon/pruning-rose-of-sharon.htm
The front of our home gets the morning sun and stays sunny until about 2 PM. We have two hydrangeas near the windows pictured, but they never seem to bloom and haven't really taken off. There's a rose of Sharon in the center that's getting a bit unwieldy. I'd like to remove the rose of Sharon and I'm looking for something that will fill the space that is interesting and has good scale. If you have any ideas on what to use in place of the rose of Sharon or why the hydrangeas are blooming, we'd love to know. We live in a suburb of Indianapolis and don't have great soil .
