Question 1

How often should I aerate my lawn?

Accepted Answer

Aeration is recommended at least once a year in the fall, with an additional spring aeration encouraged to further improve soil health and promote strong root growth.

Question 2

How do I know when I should dethatch my lawn?

Accepted Answer

If your lawn feels spongy underfoot, looks thin or patchy despite watering, or water seems to run off instead of soaking in, you may have a thatch problem. An easy check: pull back a small section of grass—if the brown, matted layer between the soil and grass blades is thicker than about ½ inch, it’s time to dethatch. In the Tri-Cities’ dry climate, dethatching helps your lawn breathe, absorb nutrients, and grow thicker, healthier roots.

Question 3

What is the benefit of overseeding?

Accepted Answer

Overseeding helps fill in bare spots, improves lawn density, and enhances overall turf health. Tri-Cities summers are brutal on lawns. Overseeding helps your yard recover from 100° heat, patchy irrigation coverage, and seasonal die-back - so it comes back thicker and stronger instead of weaker each year.

Question 4

How do I know when my lawn needs soil hydration treatment?

Accepted Answer

If your lawn dries out quickly, develops hard or cracked soil, or water seems to bead up and run off instead of soaking in, your soil is likely becoming hydrophobic. You may also notice dry patches even though you’re watering regularly. In the Tri-Cities’ hot, dry conditions, a soil hydration treatment helps water penetrate deeper, improves moisture retention, and keeps your lawn healthier between irrigations.

Question 5

When should I schedule sprinkler blowouts?

Accepted Answer

Sprinkler blowouts are best done in the fall before winter to prevent pipe damage from freezing temperatures.

Question 6

What are the benefits of fertilizer, and how do I know if my lawn needs it?

Accepted Answer

Fertilizer provides the essential nutrients your lawn needs to grow thick, green, and resilient, strengthening roots, improving color, and helping grass withstand heat, drought, and foot traffic—key for the Tri-Cities’ demanding climate. Your lawn may need fertilizer if the grass looks pale or yellow, growth has slowed, thin spots are appearing, or it’s been more than a season since the last application; if watering and mowing alone aren’t producing a healthy look, your lawn is likely ready for a nutrient boost.
