Lawn Irrigation FAQs, answered by experts

If you use a starter fertilizer designed for this purpose, you can overseed and fertilize at the same time. If you opt to use a fertilizer for established grass or one with a weed control component, it's best to wait at least four to eight weeks after seed application to allow the new grass to take hold and establish itself. 

Instant greenery, erosion control, and no waiting for germination make sod a preferable choice.

You can thicken new grass by using fertilizer, watering it 1 to 1½ inches per week, mowing when it is at an optimal height, and preventing weeds. You should fertilize your grass while you plant the grass seed, or soon afterward. Use an herbicide to prevent weeds or spot spray with herbicide to kill existing weeds.

Yes—lawn renovation can turn your lawn from damaged to healthy in one month or less. You should also consider lawn renovation an investment in your home’s future. Not only will a lawn renovation ensure that you have a beautiful, healthy, and thriving lawn, but when it comes time to sell your home, the curb appeal will increase your home’s value.

The time you should wait before walking on new grass depends on whether you used seed or sod. If you laid new grass seed, it's best to wait about eight weeks before stepping on it, as new grass is fragile. For sod, it typically establishes itself in the ground in about two weeks. For heavy traffic, like driving a car across a new grass driveway, you might need to wait an entire season.
