    My best advice would be not to do this technique. I would place the raised beds on either side of the plant.

    Absolutely! Sometimes a transplanted rose of sharon will look sad for a bit, but don't give up, it should rebound nicely!

    Some varieties may be a little less tolerant of full sun, but this will not usually hurt the blooming process. It can be attributed to nutrient deficiencies, or moisture issues if water collects in the area. This article will help you start determining what could be the problem: https://www.gardeningknowhow.com/ornamental/shrubs/rose-of-sharon/rose-of-sharon-not-blooming.htm

    The lichen, its self, is not a concern. This can, however, indicate that there is another fungal infection present and doing damage to the tree. I would recommend putting wettable sulfur and dolomitic lime around the soil and even a little further from the shrub. This will kill off anything in the soil. Doing this over the winter will give you the advantage as well. The new growth in the spring will be back to normal.

    Rose of Sharon is hardy to zone 5 and you are in zone 5b, so you are cutting it close. You may have a couple varieties with a slightly different cold tolerance. Plus, Rose of Sharon shrubs are susceptible to winter injury. To tell if they are alive, pull back a branch and see if it is supple or brittle. If it snaps off the branch is dead. Also you can scratch off about 1/2 inch length of bark to reveal the layer below it. If it is brown, the branch is dead. If it is green, it is still alive. If it seems to be alive perhaps they don't get as much sun as the others and are lagging behind. You can try cutting the shrubs close to the ground to see if they will come back from the roots. If you don't see any new growth within a month, then replace them.
