I planted a lilac from a local nursery last spring. It bloomed last year and looked magnificent (if tiny!) This year, it's struggling with something. It never really fully leafed out and today I see that over half of it has dead leaves, and the flowers on that side are drying up and dying, too. I took a couple of pics that I'll attempt to post here. You can see that on the branches, there are white "dots"... I'm wondering if this is scale? I'm originally from So Cal and living in Western Richmond, VA (zone 7a) so I'm not familiar with some of these diseases/pests out here :) Sorry if the pics don't give you enough information. I can take better ones if you tell me what you need to see! Thanks a million in advance!
