Transplanting Wisteria Seedlings

Question

I have a beautiful Wisteria vine in front of my home. I think it is as old as the house! I potted two of the seeds this year and they came up in thin green stems. The stems are growing very high. Are they supposed to grow so high? They do not seem sturdy. Should I transplant them into the ground now? They are about 15 cm high. There does not seem to be any ‘log’ to the plant, only vine. Should I trim the tops to nourish the middle?
Please help. This is my first attempt, as I just moved to this house and the flowers are so very beautiful. I would like to start another vine in the backyard.

Answer 1

I would keep them potted for another season and then transplant. These articles should help for future reference: https://www.gardeningknowhow.com/ornamental/vines/wisteria/transplant-wisteria-vines.htm
