Thank you for your advice, James and Renate. I failed to mention that we had mechanically aerated the day before, so we're good in that respect. You are right - I do need a soil test, however, we are very alkaline in Utah. I'm pretty sure there's not much "soil" left in the lawn area - just dirt. This is part of the reason I'm worried. That and I know how much synthetic fertilizer, 2-4D, etc. were applied for the first 8 years we lived here. D: There are 2 areas where the grass was killed out from a tetherball stand several years ago and neither grass nor weeds have filled in. DH is applying milorganite right now (we can't use the chicken manure due to my life-threatening allergies, so I hope this is a good 2nd choice). I think I'll wait and see if any of the seeds sprout (2-3 weeks???) and then (either way) apply a layer of compost and seed again. I'm doubtful they'll sprout because they probably won't even make contact with the soil/dirt because of the layer of cut grass. So, maybe I should just go ahead with the compost and reseeding now. Hmmmmm..... Meanwhile, I will get a soil test. I would love to hear your opinions/suggestions.
