What is Lawn Scarification?
Lawn scarification is the mechanical process used to remove excessive amounts of thatch from your lawn.
This is a very important part of the lawn care and maintenance required to achieve a strong healthy lush lawn.
Scarifying is done using a mechanical lawn scarifier which has adjustable steel blades to cut the thatch away from the healthy grass.
This process can also support the aeration process and the quality of your lawn grass roots.
Why is Scarification needed ?
Scarification is necessary when thatch in the lawn becomes excessive and begins to damage the grass. Too much thatch in your lawn can suffocate rather than protect plants, stopping them getting the necessary light, water and air that they need. In itself thatch isn’t a bad thing – a layer about 0.5-1cm thick is acceptable, thicker thatch will begin to damage the grass and removing the build-up will improve the health of your lawn ultimately making it more resilient and support good growth.
What is Thatch?
Thatch occurs naturally but as with many plants, over time old grasses,leaves and other vegetation die away and are replaced with new ones. The dead material can be slow to decay as it sits in a spongy layer under the green sward of your lawn.
Having some thatch under the top surface of your lawn is not a bad thing as it acts as a protective layer, shielding both soil and grass plants from the elements.
When should I scarify my lawn?
scarification should be carried out in the late summer and early autumn as this provides better results in terms of recovery. We advise that scarifying is carried out between mid-August and October because the warmth and moisture present in the soil in the autumn will help the lawn to recover more quickly. You can also scarify your lawn in the spring time, but this should only be light rather than heavy duty as the summer months can be detrimental if there is particularly hot, dry weather. Scarifying should not be done during winter – doing so at this time of year is more likely to damage your lawn than actually improve it.
