The weird thing is that the liliac was here when we got here (2 yrs
ago) looks like its been quite a while too.

I know its hard to remember when things start happening or change
sometimes. But I am sure this lot was ok earlier in the year. Its the
couple of times we had prolonged rain that seemed to set it off. I was
presuming that improving the soil (was just the liliac and lawn before
we came) would help with this problems.
