I wouldn't cut or repot. Is there any way you can add to the trellis? All my passies that are grown on trellises overgrow them. I usually have them close enough to some other structure that they can continue to climb on or if necessary I just wrap the stems around the plant. If you cut them back it might take quite a white to start blooming again. Actually I don't believe I've ever had a passie on a trellis that didn't overgrow it. I try to grow them along a fence when possible just for that reason.

Thanks for your reply. I won't cut or repot. I'm getting a trellis to attach to my garage and just let it keep growing. When I bring it in for the winter, do I cut the entire plant down, or just cut what's on the trellis.
Thanks again,
Barb

I cut them way back because of space issues. You can cut it back enough to easily move it or it can be cut back almost to the soil. If you are going to keep it growing inside over the winter I'd get a small grow light. You can also allow it to go dormant over the winter. It can go into a garage or dark basement. Either way you'll cut back on watering while it's inside. If dormant you'll barely have to water it at all.

Thanks for the information. This is my first passie and it's so beautiful, I don't want to lose it.
