Overwintering and Pruning

(Question)

I want to overwinter a passion flower vine and a mandevilla plant in a dormant state. Should I prune them first? If so, how severely should I prune them and do you have any tips to ensure success?
Thank you so much.

Thank you for contacting the Toronto Master Gardeners.

Two of our earlier posts titled Passion Flower – Overwintering and Wintering a potted Mandevilla contain information on how to go about overwintering your annual vines.
