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

I dug up two young plants. I gave my mother one and hers has bloomed both years, but mine hasn’t. I fertilize 3 times a year and it grows, but, no blooms. What else can I do to get it to flower?
First, check your growing conditions based on the info in these articles:

The plant blooms best in full sun. Also, I'm wondering if it is getting too much fertilizer. Try adding compost in the spring instead of fertilizer. None of the articles I read mention adding fertilizer, but it likes "moist, fertile soil."
Plants are approx. 2 yrs old and haven't developed seed pods before.
You have a couple choices. First, let the seed pods dry on the vine. If you want to plant the seeds elsewhere, remove the pods and, when they're totally dry, break them open and collect the seeds.
Your other choice is to leave them on the vine until they dry up and break open on their own. The seeds will drop onto the ground and you'll have lots of new bower vines in the spring. Good luck with this beautiful vine. Here's an article for you: https://www.gardeningknowhow.com/ornamental/vines/bower-vine/growing-bower-vine-plant.htm
When planting a new plant, it is best to assume that it will not flower until the following year. This will allow it time to settle in and adjust, focusing on roots, so that it can flower the following year.

I had wonderful luck back in the Carolinas with my harlequin glory bower. They were great understory trees to have in front the tall spindly long needle pine trees. They flower extensively I moved to camano Island in the Puget Sound. My son gave me one 6 years ago . This year is the first time it flowered but only a few. Also the first year there were sprouts. What can I do to help it flower more? Thanks in advance, Mary Michel
It will come down to environmental conditions for this one! It Does enjoy a bit of shade, so providing a little during the middle of the day might help it some.
The next thing to check will be soil fertility. Many times, excess nitrogen can be the cause of this. I would conduct a soil sample and test for deficiencies, toxicity, pH swings, or other issues that may be causing this in the soil.
They do not like, constantly wet soil. They are well adapted and can withstand mild drought conditions, so letting them dry out, thoroughly, or only providing water during drought will be beneficial.
