Lawn Irrigation questions, answered by experts

You should put pre-emergent herbicide and fertilizer on your lawn in the spring. Pre-emergent herbicide keeps weeds from taking root. Fertilizer helps your grass to grow lush and dense and blocks future weeds from growing. You can also add amendments, such as sulfur and lime, to enhance your soil quality. 

If your lawn and general landscape are struggling, consider calling a local landscape specialist to suggest lawn amendments, local plants, and hardscape changes to boost the long-term health of your outdoor space. While you may be able to take on small projects yourself—such as reseeding your lawn or testing the soil—a professional can help you build a plan to bring a struggling yard back to life quickly.

Costs range from $50 to $200, depending on lawn size and method used.

Whether or not grass will fill in bare spots itself depends on the type of grass you have. For example, grass with rhizomes (e.g., Bermuda grass) and stolons (e.g., Saint Augustine grass) will naturally fill in bald spots as it spreads laterally. However, clump-forming grasses will not spread. 

Don't pick up or dispose of aeration plugs. They will break down by themselves in one or two weeks. Rainfall will speed this up, as will watering the lawn. Mowing helps, but don't mow the grass too soon post-aeration. It's unusual that the plugs would remain after three or four weeks, but mowing and raking will break them down by that point.
