I have a lawn with yellow patches, thinning of the plant and lost root structure. I have fertilized with no improvement. What are the corrective actions that I need to take to improve my lawn?
You may have grubs or a fungus. Both would cause these issues. These articles will help you determine which:
I have beetle grubs for the first time and they have destroyed a big part of my lawn. I’m told nematodes (ready in May) are best, BUT if I wait about six weeks more, more of my lawn will be ruined. Any advice on what to do now?
Neem oil would still be effective this time of year. This article has more info on neem oil:
I have a large area of side lawn that is totally brown (I think dead), possibly killed by grubs. Is there anything I can do now in the spring to bring this grass back? What do I do to get it green?
You'll first need to take care of the grub problem, then you can focus on fixing the grass by either re-sowing the dead area or re-sodding. You'll also have to fertilize it. Occasionally, the dead grass will come back on its own following grub and fertilizing treatment.

My front lawn is completely none existent – think dirt lot. Every spring we have a gentleman that sprays the entire yard for weeds (works great on the back yard). Could this be the cause of our troubles or do we have some kind of lawn disease?
There are several things that could be causing this. My initial thoughts would be that you have severely compacted soil, or the type of grass you had planted in the front is susceptible to the weed killer that you are having sprayed.
Diseases and pests normally show themselves in patches and spots that spread to take over a lawn. They normally do not strike a lawn all at once.
Examine your soil and see if it seems compacted and if it is, aerate the lawn. Also do some research into what you would like to reseed the lawn with. You may find that a different variety does much better there.
It sounds like you have some drainage issues, which may be causing the lawn to become soft. You can regrade the yard some by adding thin layers of topsoil over the grass in the trouble areas and around the house, sloping slightly so that water/rain runs away. You will probably have to do it a few times, but just add a thin layer of topsoil, not enough to completely cover the grass but enough to bury the grass about half way up the blade. Once the grass has re-established at the higher level, do it again until the drainage issues are gone.
