We have a white flowering lilac which we have tried to deadhead religiously
immediately after flowering. The tree is, however, by now so large that
deadheading it completely is no longer an option for ancient folk like my
wife and I.

Is it really necesary to do this chore, or is it an old wives' tale?

I don't head mine. They still flower.
