I live in a new house in the northeast and have never had to tak ecare of lawn before other than mowing.

When should I start fertilizing? Now? April etc... what type of fertilizer should I use for first application? I also have some areas that have what I consider "unhealthy lookig areas" (not completely bare areas just areas that may need seed)... when is best time to seed?

Thanks

Now, and now. You can use a "feed and weed" mixture to promote healthy grass growth, and at the same time help prevent weeds.
