Lawn Irrigation questions, answered by experts

Yes, you can overseed your lawn without aerating it, but results may vary. If you have the time, dethatching or aerating your lawn before overseeding will yield the best results. Overseeding your lawn without aerating will work, but less seed will take root. For the best possible results, aerate your lawn before overseeding it.

Carpetgrass is a low-maintenance grass requiring little fertilization that thrives in subprime growing conditions. However, regular mowing is necessary to avoid the growth of unsightly seed stalks, and you may have to water it frequently to prevent drying out the soil. That includes watering the grass over dry winters to help keep it healthy, and it may start dying out in particularly cold climates where it grows poorly. Carpetgrass can also be vulnerable to some types of turf fungus, so it’s important not to overthatch. 

Fescue grass is a relatively low-maintenance grass type, meaning it doesn’t require much more attention than regular watering, dethatching, and mowing. Some fescues even grow slowly enough for hard-to-reach areas, particularly those inaccessible by the mower. Following a seasonal maintenance schedule will help your fescue lawn stay green, healthy, and durable for years to come.

Yes, it’s worth aerating a lawn. Even the most diligent mowing, watering, and fertilizing schedule is not enough if the roots are not able to benefit from the care and nutrients you’re giving them. Even a lawn that’s already healthy can benefit from aeration because the more air that circulates around the roots, the stronger and healthier it will grow. 

Lawn aeration and dethatching are meant to solve the same problem, loosening up compacted soil so that the root systems can grow and receive more water, oxygen, and nutrients. Aeration is the gentler option and often the preferable one. Dethatching completely tears out the thatch layer of the lawn and can inadvertently yank out healthy grass if done incorrectly. Aeration loosens the soil and only removes small cores of it.
