Lawn Aeration and Dethatching Services in Castlegar and Trail

WHAT IS THATCH?

Thatch, a layer of organic debris found between soil and grass roots, consists of a mixture of dead and living plant material. While a thin layer, less than 1/2-inch thick, offers benefits such as moisture retention and temperature regulation, excessive buildup, over 1 inch thick, can be detrimental. Thick thatch inhibits water, nutrient, and air penetration, leading to stressed grass roots, suffocation, and increased susceptibility to disease and pests.

WHEN TO DETHATCH YOUR LAWN

Before initiating dethatching, it's crucial to assess your lawn's thatch layer. Use a garden trowel or spade to dig up a small sample, allowing you to measure its thickness. If the thatch exceeds 1–2 inches, signs of poor grass color and weak growth may already be evident, indicating the need for dethatching.

Timing is key when undertaking dethatching, aligning with peak growth periods for your specific grass type. For cool-season grasses target late summer or early fall, while warm-season varieties grass are best dethatched after spring green-up, during early summer's peak growth phase. Avoid dethatching during periods of dormancy or stress to prevent irreversible damage to your lawn.

Although lawn aeration and dethatching are distinct processes, they can complement each other effectively. Aeration removes soil cores, including thatch, facilitating water and nutrient penetration and preparing the thatch for removal. Dethatching, on the other hand, cuts through the organic barrier and removes accumulated debris, promoting healthier soil and grass growth.

HOW TO DETHATCH YOUR LAWN

If your thatch layer exceeds 2 inches in thickness, it may be advisable to seek professional assistance for the task. Dealing with excessive thatch may require multiple removal sessions, and attempting to remove too much at once can risk damaging the grass roots.
