For use on gravel areas, paths and drives, along fences, around sheds and greenhouses.

How to use And if you don’t know what scarify means, this is when you remove all of the debris from the lawn using a special tool called a scarifier. Can be used on new lawn once the grass is growing well (around 2 months after seeds are sown or turf is laid). Also, you may find that some lawns are prone to a build-up of thatch so the lawn will need to be scarified every year.

I was under the impression that weedkillers killed anything growing plus insects and fish, but this seems a bit gentler because it doesn’t contain any glyphosate. Our selection of scarifiers includes those that are aerators. This is an effective way to help bring your lawn to life. The sandals are easy add-ons so you can use the aerator where the work is necessary.
