My cal. lilac is turning brownish. I have never had to water it during the
summer and it has always been very green a lovely all season long. This year
it is starting to turn a brownish color and looks like it has lost a lot of
leaves. Our neighbors sprinkler system has a leak and was leaking well over
a week before they turned it off. The didn't even know it was leaking, duh,
I had to go over and tell them. The neighbor still hasn't fixed their leak,
they just turn their sprinkler system on/off manually but have forgotten it
last week for 2 days. Our property got the run off from the leak right where
my lilac is. Would too much water cause this? Well it rebound?
