curling up on my lilac
I planted a Charles Joly lilac about 2 ft tall in 2008 June, and it grows out lots of new branches and the leaves in early spring this year, but it got curling up on all the leaves since 2 weeks ago ( no dry yellow leaves yet) and it's not becoming any better after watering it.
I have a golden elder and a amur maple next to it and growing
Is it anything to do mulching the pine barks around recently?
