What time of year is best to scarify a lawn? Strictly speaking, spring is the best time to scarify. However, there is a danger that you will have to endure beautiful summer weather with a lawn that's not looking its best and is still growing back.
What month should I scarify my lawn?
October - Often considered the best month to scarify your lawn, it is in fact rather late. Temperatures drop and green growth starts slowing down. The wet weather combined with the cold often creates large patches of bare soil, which barely recover as is. Winter scarifying - This must be avoided at all costs!
When should you not scarify your lawn?
Alternatively, you could just hold off scarifying your lawn until a day or two after a bout of rainfall and save yourself a job. Whatever you do, don't scarify when it's wet – you could end up yanking out the grass by the root, removing the grass itself as well as the thatch.
