A de-thatching rake also known as a scarifying rake should be on the list of everyone who has a lawn. All lawns will benefit from scarifying in spring and autumn to remove a build-up of debris which will make the grass grow stronger and help prevent moss taking hold.i
A build-up of debris such as leaves and dead organic matter known as thatch will block out the light which grass needs to grow and hold in moisture. This provides an ideal environment for moss to flourish. A de-thatching rake will remove this debris.
How does a de-thatching rake work?
A series of blades or tines on the head are set at 90 degrees to the handle. These are made of carbon steel or stainless steel and the shape is usually a crescent or a similar variation.
The blades are designed likes this so they only cut on the pull stroke.
To use the de-thatching rake you simply push it forward, and as you pull it back the blades or tines dig into the lawn and remove the thatch, moss and other types of weeds.
Types of de-thatching rakes
If you have a small to average lawn then a de-thatching rake with a handle will suffice. Because de-thatching a lawn can be strenuous bigger lawns are best de-thatched with a rolling de-thatching rake.
These are similar to a normal de-thatching rake but have wheels which make the task much easier. They have blades with an oscillating action and a long handle to avoid any stooping and back strain.
One drawback is that they will not get right to the very Scarifying Rake
edge of the lawn due to the wheels. The amount they miss is approx 3 inches or 75 mm which is the distance from the outside of the wheel to the first blade.
When doing any maintenance on de-thatching rakes always wear thick gloves the blades are incredibly sharp.
All plant debris should be brushed off the blades, do not use a wire brush or anything metallic as this could damage the blades.
If you have a roller rake make sure there is no debris around the wheels and give them a light oiling at the end of the axle.
If you have carbon steel blades wipe them over with an oily rag to prevent rust.
Replace the blade cover before storage and keep out of reach of children.
Put any thatch on your compost heap if you have one.
If you have a rolling rake, you may want to purchase a rake with a handle as these get right to the edge of your lawn, where the rolling rake cannot get to
