Answer: I agree, 5 years is a long time to wait for flowers! English laurels bloom on new shoots and stems so in very early spring (about March) prune the stems back on your laurels. You only need to take a few inches off (try to prune back to a node or leaf scar). New growth will emerge (which will help keep your shrubs thick and dense) and flowers should develop on this new growth.
Best wishes with your laurels!
