Answer: Not all plants will root in water, but most will. Roots develop where there is a leaf scar along the stem. Make sure at least one leaf scar is in the water and the vine should root. There's nothing you can do to speed up the process. It takes the plant a while to decide it is no longer attached to the plant. Then it spends time keeping hydrated by drinking up the water. Then it decides to develop roots. All these processes take time so just be patient with your vine.
