Four inches is too close - it'll be in the 'rain-shadow' of the wall - I'd move it to about 18" from the wall and prepare the hole by digging in lots of leafmould or home made garden compost - what you're looking to do is to mimic the conditions of a shady wild hedgerow or damp woodland.
I'd do it now, and cut it right back. It'll grow thicker from the base next year. In Feb give it a sprinkling of Fish, Blood & Bone - it'll be fine
