Wisteria

Question

My sister is wanting to get a wisteria plant and is wondering if it can be grown indoors. We live in central Missouri where winters are fairly cold, sometimes getting to zero or below. Summers are hot and humid getting as high as 100 with 70-95% humidity at times. Is there any way she could grow a small vine just outside her apartment door? And what she would need to do to keep it from dying in the winter?

Answer 1

Wisteria normally do not make good container plants because they grow too big and too fast. but, that being said, if she uses a big tub, they may make it. It won’t stay small though.

In terms of cold, if you live in Zone 5 or higher, it should be fine in a container with no extra care but if you live in Zone 4 or lower, it will need extra protection. If you are in Zone 4, wrapping it in burlap and hay or leaves or moving it near a south facing wall should protect it enough for the winter. In Zones 3 or less, you would need to move it to a protected area, like an attached garage.

In terms of the heat, once temps go above 85 F, the container must be watered twice a day. And if they go above 100 F, three times a day is not too much.
