I'm in Zone 4 (Toronto, On)I just bought My hibiscus this year (about 1 ft tall) and was giving wonderful bloom all year. NOW, winter is upon us and it has no more buds and has some of the leaves are drying up and falling (although stems are still nice and green).

I wanted to know:

What is the best way to prune it (if necessary)?

What time of year can I prune?

How much can I cut off?

Any other autumn/winter advise would be greatly appreciated.

Thanks
