How To Use A Lawn Scarifier

Lawn scarifiers are very good for keeping your lawn healthy, they take away the dead grass and mosses and other detritus that is commonly known as thatch. If the thatch stays on the lawn the grass will suffer, because it will be deprived of light, water, nutrients and oxygen.

What Type Of Scarifier Should You Buy?

There are 3 types of scarifiers: they are manual,electric-powered and petrol-powered. If you only have a small garden and/or a small budget a manual scarifier will probably suit you best, but they can be hard work to use.

Electric-powered are a good fit for middle sized gardens, but the cord can be a bit of a nuisance, although there are a few cordless models available nowadays.

Petrol-powered are the most powerful, the most noisy, and the most expensive. Plus they need regular maintenance and fuel top ups.
