Lawn Fertilization and Treatment questions, answered by experts

Depending on the lawn treatments, the best times of the year to redo your lawn are between mid-August and mid-September for overseeding and renovation treatments. For areas such as the southern United States, lawn aeration works best during the fall, when the temperatures begin to drop. Otherwise, early spring is your next best bet because the grass is fresh and ready to absorb nutrients, and the temperature isn’t hot enough to fry the grass and the renovation materials.

When hiring a lawn aeration professional, they may suggest other related services to get your lawn looking lush and fabulous. Prior to scheduling any of the following services, you should consult your lawn care pro about the order and timing of multiple projects to ensure best results for your grass. These services might include:

You don't want to over-fertilize your lawn because it can burn the grass and even kill it. Healthy soil usually requires two fertilization applications a year during the height of the growing season. This fertilization schedule typically starts at the start of fall and the end of spring, depending on the grass type and plants.

Yes, in most cases, grass will return after your dog urinates on it. But without preventative measures, there’s always a chance your dog will pee on the grass again, leading to brown patches come summer. This aside, even if your grass is dead in patches, simply reseeding the dead spots should help restore your lawn. 

If you choose not to reseed your lawn, unaffected grass surrounding the dead patches will spread over any dead spots. But be prepared for this option to take longer—you likely won’t be able to grow grass fast.

Some of the particular herbicides that work best to get rid of nut grass without killing the grass include Halosulfuron-methyl, mesotrione, sulfentrazone, and metsulfuron. A herbicide like glyphosate would kill nutgrass, but it will kill nearby plants, too.
