Rose of Sharon can suffer from a number of pests and diseases. You can move your shrubs to the garage or anywhere it is above freezing to get them out of your living area. Neem oil may help with the bugs.
Does it get below -20 F (-29 C) in Richmondhill? That is the minimum winter temperature for Rose of Sharon. If it gets colder than that, when you plant it next summer, you will have to take precautions for the next winter.
