With the Hauertkugel, Hauert introduces a fertiliser, which is an Innovation with High Quality, Functionality and Ecology. The ball is available for house and green plants, balcony and tub plants as well as for tomatoes and vegetables. It is simply stuck into the ground. Thanks to its nutrient deposit, it provides the right amount of fertiliser for a whole year or season. Alternatively, it can be inserted into the ground after planting with the help of the planting stick, which is part of the delivery. The Hauertkugel works directly at the plant, where the nutrients are taken up.
