Thanks El...
I gave them all acidophilus last year and that seemed to help... I just started them all on it again... and looking into Milky Spore for help getting rid of the grubs... I swear that is why they eat the soil.. It's always the clumps... Ugh!

I have grubs too. Not sure it is a bad problem, but there are some and they dig holes. Looks like a minefield. Good luck and I'd love to hear about the Milky Spore. Never heard of it. We hate to use any lawn chemicals.
