Thatch is a layer between the grass and the soil made up of interwoven accumulated dead and living grass shoots, stems, crowns, and roots. It creates a barrier between the soil and the green grass you so adore. A thin layer of thatch is good—about 12 mm. It helps maintain steady soil moisture and temperature which will aid non irrigated lawns to a point in summer.Get in touch
WHAT DOES DETHATCHING DO TO MY LAWN: -
Controlling thatch is one of the most important – and most overlooked – parts of lawn care. Thatch is simply the layer of dead grass, roots, and debris that accumulates between the soil surface and the green grass blades above. … If your lawn is small, you can dethatch it with a special dethatching rake which we call a turf rake … if your lawn is a big lawn you can use a mechanical dethatching machine.
WHEN SHOULD I DETHATCH MY LAWN: -
The lawn should be dethatched when it is actively growing and the soil is moderately moist. The best time of year for dethatching is the same as for aerating: early spring or early autumn for cool-season grasses, and late spring through early summer (after the second mowing) for warm-season grasses.
SHOULD I DETHATCH MY LAWN EVERY YEAR: -
If your lawn produces a lot of thatch, example (Couch/Kikuyu and Fine Fescue) dethatch annually … so that it’s not such a major task … these lawns are revitalised after a dethatch (better colour/healthier plant). If the thatch is no more than 12 – 15 mm deep, you can probably get by with every other year. If it’s as much as 15 –30 mm deep, you might need to dethatch in spring and autumn. Generally once per year is good for high profile lawns with little wear.
SHOULD I TOP DRESS MY LAWN WHEN I DETHATCH IT: -
Generally yes … this is a great way to re establish desired lawn levels.
