Hello - a bit of an 'aspirations far beyond my experience' thing here.
I've got 40 small (6"-7") box plants, and I want to have them as a two-plants-deep border to a circular bed. I'm going to clip them into a formal shape, and the inner bit I'm going to fill with wild-ish stuff - alliums, poppies, herbs.
Does anyone
a) know how to lay a formal box hedge? Do I do it in a brick pattern? And I've no idea about how far apart I should lay them.
b) have any other easy suggestions for filling the circular bed?
