I would not prune again until mid summer when I would expect the hedge to be at least double it's current size. Possibly three times. I would prune only the sides and, even though small, would already be aiming at the top being narrower than the bottom.
By the summer of 2015 I would expect your hedge to be well on its way to your 5'. When your hedge exceeds height required start regular cutting of the top. A hedge should be wider at,the bottom...light to all parts of the hedge for good growth.....than at the top. Looks better too
A few years I planted a hedge.....escallonia....to separate a veg patch. They were not bare root but cheap in the clearance section of a local nursery. Bit root bound.....loosened roots prior to planting..... but otherwise healthy plants. They grew quickly and I followed the way I suggest above. This hedge is thick and looks good
