You're right, it doesn't say does it?
My guess is that you need a pot about the same size as the one I've got a fig tree in, which is 20" x 20" x 20"
I was just looking at my erysymum Bowles mauve - it's all straggly but still got flowers. Should I cut it back now or wait a while?
About that article, there seemed a lot of plants and the picture didn't show the whole pot. It seemed too many plants to me for a container.
I'll do it this week I think. Start to tidy up. I'll take cuttings this year.
