Lawn Fertilization and Treatment questions, answered by experts

Yes, after the lawn is overseeded post-aeration, most of the seed germinates in the aeration holes. This leaves the soil undisturbed while lush and healthy grass will grow in the holes' place. The point of this is to create extra turf density in areas that really need it, such as a large patch of dead grass where a shed used to be.

You should apply sulfur to your lawn in the spring or fall when it is below 80 degrees Fahrenheit. Aim for a day with little to no wind so you can apply it with precision. You can apply sulfur to an established lawn or mix it into the top 6 inches of soil on an unplanted area.

If you apply too much fertilizer to your grass, it can take about three weeks to recover. If you still have dead patches after three weeks, it might be time to remove the dead grass and overseed the affected area. Since overfertilizing can also cause problems with fungus, leading to further damage to the grass, monitor your grass color and growth for one month after over fertilizing.

If you plan on laying new grass seed, try to wait eight weeks before stepping on it. You might need to wait an entire season to drive your car across the driveway. Sod establishes itself in the ground in about two weeks.

Choosing fertilizers: slow-release for steady nutrients, organic for eco-friendliness, or specific blends for soil deficiencies or grass types.
