How to Care for a Wisteria Indoors

Wisteria grows as an outdoor vine that reaches a height of 10 feet or more in climates that experience minimal frost. The vines aren't suitable for use as a houseplant due to their height and light requirements, but you can force individual branches indoors for winter blooms and color. Forcing the branches to bloom inside and keeping them in bloom requires proper care during and after the forcing process. Indoor wisteria blooms in February or March, about three weeks after the forcing procedure begins.

Instructions

- 1
  Cut a 12-inch or longer branch from your wisteria vine, using sharp pruning shears, in January or early February. Select a branch that contains multiple flower buds, which are large bumps on the branch. Flower buds are larger than leaf buds.
- 2
  Fill a large tub or container with room-temperature tap water. Lay the branch in the water, submerging it completely, and soak it overnight.
- 3
  Transfer the branch to a vase filled with water. Set the branch in the vase so the lower third is submerged in water.
- 4
  Place the vase in an area that receives bright, indirect light and maintains a temperature near 50 degrees Fahrenheit.
- 5
  Replace the water in the vase every three to four days. Replace it sooner if the water becomes cloudy or develops a bad odor.
- 6
  Mist the branch with water from a spray bottle once a day. Misting keeps the humidity around the wisteria high, which encourages flowering.
- 7
  Move the wisteria to a warmer location once the flower buds begin to open, about three weeks after you bring the branch indoors. A location with night temperatures near 60 F and day temperatures near 70 F works well. Continue to change the water every three days during the blooming period.
