Lawn Scarification (Spring or Autumn)

Scarification is the mechanical removal of thatch build up and dead moss. Thatch is a build up of dead organic matter laying on the soil surface. Thatch is a natural occurrence as old grass stems die and are replaced by new ones. Bacteria in the soil digest the thatch breaking it down into nutrients for other plants.

Why scarify my lawn?

In severe cases of heavy thatch the bacteria cannot digest all the organic matter and the thatch builds up and forms a fibrous layer on the soil surface. This layer acts like blotting paper preventing the flow of moisture, oxygen and carbon dioxide to and from the grass roots. It is vital that thatch is not allowed to build up as it can have a disastrous effect on any lawn weakening the grass, encouraging moss and diseases. Scarification promotes new fresh growth which will result in a much healthier lawn.

When should my lawn be scarified?

Scarification is carried out from either late spring when the soil warms up or in the autumn when moisture will help seed germination and recovery.

How is thatch removed?

Several vertical metal blades revolve at high speed around a shaft and dig into the ground as the machine is pushed along the lawn. The blades can be set at various heights from the surface and consequently take out various amounts of thatch and dead moss. It is possible to control thatch by energetic hand raking or using a domestic electric lawn rake but the best results are achieved by using high quality professional machines.

Scarification & Verticutting Services

Single scarification means we run the machine over the lawn once to thin the sward (lawn) if the lawn is too dense.

Normal scarification is when we go over the lawn in one direction and then the other direction to thin the sward and remove thatch and moss.

Heavy Scarification is when we keep going over the surface of the lawn until we have removed the required amount this is generally when removing large amounts of moss. The process will inevitably tear up the lawn to the extent that over seeding is necessary to regenerate a new lawn.

Verticutting is when we use a fixed blade cassette to cut the surface of the lawn. This is carried out when over seeding or to promote root development and lateral growth. It also aerates the lawn surface.

Heritage can advise you if your lawn requires scarifying but most lawns benefit from scarifying at least every 2 – 3 years depending on soil and weather conditions. Lawns can take several weeks to recover after the treatment but it is an essential part of the renovation process.

We also offer additional lawn care services which your lawn may benefit from. These include seasonal lawn treatments, lawn scarification, lawn aeration, lawn over seeding, pest control, disease control, lawn renovation and driveway weed control.
