Lawn Irrigation questions, answered by experts

Common tools include spike aerators and core aerators. Professionals often use motorized equipment for efficiency.

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.

Hydroseeding over an existing lawn is possible, but certain adjustments are necessary since the process is for bare soil. Hydroseed mix is ​​usually very thick, which helps protect the seeds during germination. If you have existing grass on your site and still want to hydroseed, it's better to use a finer mulch mixture when spraying. A finer mulch mix means the seeds can root into existing soil without suffocating the existing grass.

Technically, yes—and you may have some successful growth—but this isn’t the ideal way to fill in sparse areas. By clearing leaves and debris, amending the soil, and aerating it properly before you lay the seeds, you’re providing the most ideal conditions for them to germinate.

Costs depend on property size, service frequency, and additional tasks like aeration or overseeding.
