Winter Care for pandorea vine

Question

We have several (potted) pandorea vines. Since we live in zone 5 (48159), how do we care for them during the winter?

Answer 1

They bloom year round in zones 9-11. Bring it inside before the threat of frost and place it in a warm room with plenty of light and let dry between waterings. If you don't have enough light for it to bloom, you can try grow lights, or just keep it as a foliage plant till spring. Then move back outdoors after threat of frost has passed.
