Florida,
United States 
my tobouchina large leaves are turning orange and spotted and drop off, some of them. Don't know what is happening. Anyone else have this problem.? Would like some advise. Diane , dianematt2@yahoo.com

Without a photo I am guessing that these are just old leaves further down the stems? If they are, they will drop away gradually. Is it in open ground or in a container?
As long as new growth is produced it should be fine. Take the odd cutting too so that old woody plants can be replaced every few years.
