Last fall I started a lawn from scratch. I live in Northern Jersey. After
a couple applications last fall, and one more, this March, the lawn is
looking half-way decent.

However, there are quite a bit of very large bald spots. Should I use
Turf-Builder for these bald spots, or should I use new starter seed.

Also, what would be the best way to aerate this spots before setting down
the seed. I'm a little concerned that I'll destroy my existing lawn if I
scratch it with a rake.

Thanks for any advice.

Start with a soil test.
