Q: What should I keep in mind when seeding my lawn?

• <div><p>Whether you&rsquo;re putting down fresh seed or reseeding, there are a few things to keep in mind when seeding your lawn. Be sure to choose the correct seed for your climate, seed at the right time of year, and water two to three times a day for the first week. Generally, Dudley recommends <a href="https://www.angi.com/articles/plant-grass-spring.htm">seeding in spring</a> and fall as it is usually cooler and rainier. </p></div>

Q: How do I maintain my lawn after aeration?

• <div><p>Water the lawn thoroughly, apply fertilizer, and overseed if necessary to promote healthy growth.</p></div>

Q: Can you hydroseed over old grass?

• <div><p>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 <a href="https://www.angi.com/articles/choosing-right-mulch-your-garden.htm">mulch mixture</a> when spraying. A finer mulch mix means the seeds can root into existing soil without suffocating the existing grass.</p></div>

He does a good job. He will trim shrubs but he does not do that for us. He was doing the lawn before we moved in so he was familiar with the lawn. We told him not to mow the grass when it was wet and he did not. When the grass was dry we called him and he came out. I would recommend him.
