I think thyme is often neglected and dispatched to the poorest driest spots where they do well but Some thymes, ESP the woodier ones like silver posie, need a little water now and then and a light feed now amd then.
I would trim them back now but would repot them first. Perhaps into a deeper pot. Don't cut too far back into old wood.
