I laid bermuda sod in my back yard last year that came from down near the coast south of Houston. I had to water it often last year just to keep it alive. We have had so much rain this year I thought it might drown. We also have a good crop of mushrooms. I don't know if they are poisonous or not for humans or dogs. The dogs seem to ignore them. I thought maybe there was one or two products of the '60s here that might have had some experience with mushrooms. Any ideas?
