I have two lilac bushes that are supposed to be suitable for San Diego. The blue/lavender one has only a few tiny sprays. The white one, which has done better, has shown split bark, as has the blue one. Obviously, the articles about freezing do not apply. This year many of the leaves on the white are curling. I can find no pest on them, even under a magnifying glass. Am I missing something?
