Q.2 weeks ago, literally overnight our 7 foot Rose of Sharon started leaning over, more than 3 feet and has not straightened out.
All the leaves are healthy and there is no sign of damage. Why is it doing that and can it be fixed? The plant is in our front garden which faces due west
The most likely reason is that it is top heavy and the stem cannot support all the weight, so it is bending over with the overburdened load.
Thin and reduce the foliar crown by selective pruning, and consider staking the plant for additional support
