Can you just throw grass seed on an existing lawn?

• <div><p>Throwing grass seed on existing lawn isn’t likely to germinate, grow roots, or become healthy grass. You need to prep the soil, <a href="https://www.angi.com/articles/fertilizing-101-yard-and-garden.htm">spread fertilizer</a> with your seed, and sow the seed into the soil. Water the seed every day for two weeks to ensure it germinates and grows roots. Be sure to stay off the area and wait to mow until it reaches optimal height.</p></div>

Q: What is the price range for aerating a lawn based on its size and the technique applied?

• <div><p>Costs range from $50 to $200, depending on lawn size and method used.</p></div>

Q: How long does aeration last?

• <div><p>It depends on the current health of your lawn. Liquid aeration takes longer to work, but the results are longer lasting. Since you can apply the liquid solution several times during the course of the growing season, the results are cumulative. Core aeration, on the other hand, will offer quicker benefits but they will diminish sooner, right along with the soil plugs left behind.</p></div>

Q: Is it better to aerate or scarify a lawn?

• <div><p>Both aerating and scarifying your lawn can offer serious benefits. Aerating pokes holes in the soil to better allow air, moisture, and nutrients to permeate while scarifying removes the buildup of dead plant matter at the soil&rsquo;s surface. Most lawns require both of these maintenance items to thrive.</p></div>

Q: How do pros achieve effective aeration during clean-ups?

• <div><p>Using specialized equipment, they aerate thoroughly, alleviating compaction and enhancing root health.</p></div>

I respect this company highly. They are a small local company. Their installation is excellent and the selection is as well. The only time I won't go to this company is when they don't have what I want.
