Keep the wisteria vine in a sunny location. A young wisteria vine likes a sunny spot. Choose a window that gets several hours of sunlight per day.
Water the wisteria vine sparingly. Although wisteria does well in moist locations, the more water that is provided, the faster the vine will grow. Indoors, water sparingly until planting season.
Harden the wisteria vine before planting. As it gets warmer outside, take the vine and set its pot outside for a few hours a day. This helps acclimate it for planting.
