Thatch is a mix of grass clippings, shredded leaves and other natural debris that has settled around the stems of your grass plants. Just a little thatch is a great thing, helping shade the grass plants’ roots and impeding evaporation of ground moisture. But thatch over an inch deep can smother your yard, leading to patchy growth and ugly bare spots. A lawn thatcher removes excess thatch so your bud can show healthy, uniform growth.
The most elementary sort of lawn thatcher is a thatching rake, a long-handled hand tool with parallel vertical knifelike blades that pull thatch from the grass as you rake the yard. It is used on small patches of grass. For larger areas of grass, homeowners can purchase or rent thatchers on wheels that are pushed along like a lawnmower or towed behind a riding mower. These machines are sometimes known as power rakes.
Wheeled thatchers include powered models using vertical free-swinging steel flail blades or repaired vertical knives attached to a horizontal shaft that’s driven by an on-board gasoline engine or electric motor. Some wheeled types utilize knifelike thatching blades or heavy wire tines rigidly secured to a frame. The blades or tines are pulled through the turf since the unit is towed by a lawn tractor.
How Units Work
The blades or tines of the thatcher split the thatch and pull it to the surface since you run the machine over the yard. Some electricity thatchers include height and blade-spacing adjustments. Adjust the height to ensure that the blades or tines are approximately 1/4 inch above a hard flat surface such as a concrete terrace. Blade spacing is corrected in line with the species of yard grass you might have.
Utilizing Lawn Thatchers
Dethatch lawns in early spring or early fall. This lets the grass time to recover before summer heat or winter cold. Don’t dethatch your lawn in just 45 days of applying fertilizer or pre-emergent weed killers. Dethatch following a light rain or yard watering session. Before dethatching, mow the yard to half the normal height and bag the clippings. Mark places of landscape lighting, sprinkler heads and also any shallow-buried pipes or wires. Run the thatcher over your yard in 2 passes, with the second pass at right angles to the first. After dethatching, rake up the stuff for disposal or composting.
