Well, I'm going to check it out soon, Sharon. I will lift the pot ever so gently to see what is happening. If it is growing into the ground I may take your advice, but it is in a lovely large ceramic pot which will be a shame to bust up. Nonetheless, if it makes the wisteria happier in the long run, probably worth it. Now I am hoping that my grapevines made it through their first winter. Too soon to tell, but I did get them from our awesome local nursery and they are Niagara grapes... so if they can live in my old home town in Western New York, you would think they could grow here. Anyway, I digress... but I am still hoping for lovely wisteria blooms this year!
