Can I cover the bottom foot of wisteria in soil?
I have a wisteria growing against a wall which I would like to build a raised bed against. This would probably mean having to bury about a foot of wisteria under new soil. Would this be bad for the plant?

We don't recommend this. It doesn't always result in the death of the plant, but it increases the likelihood of infection. When you water the first time, replace 1/4 of the water with hydrogen peroxide. This will help kill anything off that could potentially harm the plant. Just monitor for any changes, and if you start to notice a decline in the plant's health, then uncover the plant again.
