I dug up and turned the soil over and layed sod in this area. I also turned over the soil and planted shady grass seed in the area between the existing grass and the new sod. I also patched up areas one the grassy side to fill it in. Within a week or so the grass and sod looked beautiful almost golf course like.
But now 3 weeks-4 weeks later all the new areas have thinned quite a bit (sod, patches, seeded areas). The original grassy area looks the same.
I tried fertilizing the lawn 4-5 days ago and so far no difference, everyday the lawn looks worse. More dirt less grass.
I have watered it quite a bit and it has rained quite a bit too.
Does anyone have any sugestions why this might be happening and how to fix it?
Also no one has been on the grass as its a fairly unused lawn.
