I fertilized my lawn on Sunday. Before that, I noticed some areas where some areas of the grass where light brown/yellow. Now there is a little more. How do I get rid of it so I can have greener grass?

Fertilizer will help green up healthy lawn but it won't repair dead or diseased areas in the lawn. I'd rake out the browning areas and reseed. This should help. If you encounter more yellowing or browning areas, there may be a disease present or it may be that you need to dethatch or aerate your lawn. All lawns develop thatch but a layer that's an inch or more deep can keep water and fertilizer from penetrating down into the soil. Compacted soils can do the same thing. If your lawn has heavy foot traffic, the soil may be compacted. Rent a core aerator to help alleviate the compaction problem. Good luck with your lawn.
