I have a small, fenced, townhouse backyard. The yard is in horrible
shape, although it is very green. I have lots of weeds, crabgrass,
and a few bare spots. The yard is fairly shady and has good
drainage.

It is now early December (Northern Virginia).

I do not want a perfect yard but would like to do what I can to
improve the current situation.

What are the best, fairly low maintenance, routines for clearing up a
weed infested yard. I'm guessing it has never been fertilized and I
do know there is a grub problem.

Thanks
