Oleanders – Winterize
I have a couple oleanders that are in large pots. I live in Southern Ontario, Canada and winters can get relatively cold (well below freezing). I typically bring them in the garage for the winter and wrap them in burlap. Last year one died due to cold. I can only guess. My question is, what is best to do to winterize the plant? Do I still water them a bit if temperature is above freezing? Thanks, Paul

Oleander are winter hardy down to zone 8.
Even wrapping and storage inside will likely not be enough to get them through the cold temperatures in your zone.
You could move indoors instead. Prune the plants back prior to doing so.
Remember the safety issues with Oleander. All parts of the plant are poisonous.
