I'm sorry, I meant lime instead of calcium. (I am an amatuer)The yellow spots did seem to be where the straw was bunched up from when the rain washed it together in clumps now that I think about it. I am thinking maybe it is from holding the moisture in in those areas. We did do a soil sample, and where we did it we took the appropriate steps.( I do not remember exactly what that was.....MY wife took care of that part) Do you guys still think we s hould fertilize it again? Any other suggestions before going into the winter. I have also heard that if you need to seed that you should seed right before a big snow. Is that true, or is that just an old myth? Thanks again guys, you have been very helpful.
