Correct fertilising - Food for your lawn
Usually two fertiliser applications (spring & late summer) per year are enough, provided that cuttings are not regularly returned to the lawn through mulch mowing (please also see the article by our garden expert Andrea Heistinger). Nutrients are essential for the grass, especially nitrogen (N), which promotes cell division and consequently the formation of every part of the plants. Good lawn fertilisers contain additional potassium, for fortification against disease and phosphorous, for the promotion of root growth, in well-balanced proportions.
The lawn should also be scarified before the fertiliser is applied, so that it is easier for nutrients to reach the soil. It is recommended to allow the lawn to grow a little before actually applying fertiliser. Consider also that the fertiliser should never be applied under conditions of direct sunlight and ground frost. After fertilising, water thoroughly and generously. The lawn should first be mown a few days after applying the fertiliser. The lawn height before fertilising should be approx. 5 cm. Remember the golden rule of fertilising: everything in moderation … like so much in life.
However, fertilising not only supports the supply of the required nutrients to the soil. It can also be of assistance in combating weeds. Certain fertilisers help to eliminate clover and dandelion. Pay close attention to the manufacturer's information when purchasing.
Attention: Do not use nitrogen fertiliser during autumn.
