Aeration helps grass roots grow deeper, reducing the damage Texas droughts cause to your lawn. This is a must if you're wanting to achieve a stronger, more vigorous lawn.
The best time to aerate is when the grass is in early-mid spring or at the end of the season, in early fall. Avoid aeration during the hottest months as this stresses the grass. Aeration is suggested yearly for heavily compacted soils, and bi-yearly for peak maintenance. Spring Aerations are best paired with an Overseed or Fertilizer.
Aeration is the first step to repairing drainage issues for a lawn that never seems to retain the water. Removing plugs allows soil to EXPAND & increases air/water penetration within the soil, creating a better growing medium for your grass.
Dethatching removes the dead brown grass that has accumulated over time, causing the green of the grass blades to solely show it's beautiful color.
Heavy Thatch can create a barrier that prevents water and nutrients from penetrating the soil. This causes water waste from runoff and also what's called "Shallow Root Syndrome", where grass roots aren't able to grow PAST the thatch-line. This makes Texas summers near impossible to get through without without almost daily watering.
Dethatching should only be done around every 3-5 years and will need to be done more often when you have more clay in your soil.
