"Harry was terrific! He turned my poor experience into to one I can manage until I get a new irrigation system placed. Even better, he drove about 2 hours out of his way to help me then only charged me half since everything I was handed from the prior service company! Definitely recommend Harry."

Lawn Irrigation FAQs, 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.

Shade-tolerant grass seed still needs between four and six hours of sun to germinate, and many types require a little extra care to thrive. However, it is possible to plant new grass seed in shaded areas when you choose the right variety.

Having a luscious lawn won’t take a century to grow with hydroseeding—most hydroseed lawns sprout within 7 to 14 days. Once the new grass is about 4 inches tall, which is about six weeks after the installation, it’s ready to mow. After the initial mow, keep foot traffic at a minimum for another four weeks to solidify the rooting system.

Morning and late afternoon are the best times for watering new grass seed. The seed gets a healthy balance of water and sunlight, and the excess water evaporates. If you water the grass long after the sun goes down, the air is too cold, and there's no sun to make excess water evaporate. This keeps the grass damp for too long, increasing the chances of over-watering.

No, it's not a good idea to put grass seed directly on top of dead grass. For successful germination and growth, grass seed needs good soil contact. To prepare the area, start by removing the dead grass using a shovel or a sod cutter. Then, loosen the soil, add soil amendments if necessary, and spread the grass seed evenly. This allows the seed to come into direct contact with the soil, promoting better germination and establishing a healthier lawn.
