Lilac hedge not flowering as abundantly

My mature lilac hedge has gradually decreased in it's flowering. I plan to rejuvenate which I haven't done (although storm damage has done some!) for years... I have built a bed around them and will mulch with some organic matter. What type of fertilization is best for the hedge? And I imagine now, post flowering is the time for deadheading, rejuvenation and fertilizing??
Thanks,
nancy
