Help with my new hedge please :)

[Titsywoo]

Just planted 7 of these to cover up an ugly bit of fence that I can't remove. Never planted a hedge before so no idea what to do to make sure it gets dense and bushy from the base upwards as quickly as possible! Do I prune it now or give it time to grow and do the first cut back in spring?

Oh and I planted 3 per metre as suggested

How tall are they at the moment, and are they bushy or a bit spindly?

I've got a hedge of these, they're taking over the whole garden, so in my experience, which is sunny location with heavy clay soil, trim a bit now and again in the Spring. You need to keep them under control and they'll keep coming back at ya. General rule of thumb is to keep pruning for a thicker base and these do send out long shoots early on in their growth.
