How much of our Organic Lawn Compost you need to apply largely depends on how you want to use it. For creating new lawns, you will need a layer of compost about 1 to 2 cm thick. Here our 40l bag of compost is enough to cover an area of about 2 to 4m2. If you want to use it for reseeding, you only need to spread a thin layer over the lawn - a few millimetres are enough. In this case, one bag will be enough for about 10m2.
