Trees, Shrubs and Conifers: Japanese Ligustrum leaf spots, 4 by firstyard

firstyard wrote:
All 4 of my Japanese Ligustrums have that fungal disease that causes yellow and brown leaf spots. From 30% to 70% of the leaves that are left on each shrub are affected. Leaves are quite thinned out. Is it too late to save them?

If not, I know I need to:
a) spray them with a fungal treatment (any suggestions?)
b) clean up leaf litter

What else? I noticed they are getting new growth. Should I fertilize? (It's abt 2 1/2 - 3 mos. till our first frost.) I don't water overhead. In fact, until a couple of weeks ago they have subsisted on rain for the last 5 years. I need to take better care of them in general.

Any help appreciated!
