Lawn fertilizer - the most important ingredients

The Content Of The Article:

Lack of minerals and trace elements can cause the lawn to show bald spots or light growth. If the lawn does not shine in a rich green and does not form a beautiful, homogeneous green area, it requires a corresponding lawn care. The higher the strain on the lawn, the more intensive and targeted the supportive care.
Balanced fertilization helps the grasses to absorb missing nutrients and prevents the spread of weeds. However, the slogan "a lot helps a lot" should not be used, but attention should be paid to the correct composition of the fertilizer.
The most important ingredients in the fertilizer and their effect
Of the basic ingredients such as water and oxygen that the lawn needs for healthy growth, nitrogen, phosphorus, magnesium and potassium are the main nutrients. These elements are usually found in a lawn fertilizer, in suitable composition. A balanced mixing ratio is the basic requirement for good turf development. Here, the nitrogen is given the greatest importance and serves mainly as a growth engine.
Special trace elements such as sulfur, calcium, iron or zinc can be added to the lawn in small quantities as needed. However, they are usually available only in the form of special fertilizers and are rarely responsible for a basic nutrient deficiency.

  • nitrogen: Promotes growth and regeneration ability of grasses, ensures healthy green color
  • phosphorus: Specially promotes root growth, regulates as an essential energy metabolism
  • magnesium: Supports the green color of grasses, prevents yellowing
  • potassium: Increases resistance and resilience of the lawn, protects against periods of drought and cold, and reduces disease infestation
An even supply of nutrients promotes the maintenance of healthy grass throughout the growing season. As the growth of grasses starts around the beginning of spring, the need for nitrogen is greatest at this time. The other important nutrients are now urgently needed by the lawn. At the first fertilization, however, the nitrogen content is crucial for the nutrient mixture to stimulate growth accordingly.
Nitrogen fertilizers:
In March to April, the nitrogen component in the fertilizer should dominate to achieve quicker greening without burst growth. The main nutrient promotes both the above-ground leaf growth and the root mass itself. As a motor of growth, the high percentage of nitrogen in the spring ensures the optimal start of the lawn. In particular with frequently and deeply cut lawns the nitrogen need must be specially considered. Nitrogen forms in the fertilizer are present in different mineral compounds. Often they are offered in combination with ammonium or nitrate. Excessive application of the fertilizer, however, can lead to leaching losses for these plant-available nitrogen forms.
Potassium fertilizer:
As the days get hotter and the grass is used more often, the need for nutrients shifts. The summer is sometimes the strongest load for the lawn, so here on enough potassium must not be waived. It protects the grasses from drying out and avoids burns. Although the regeneration capacity of nitrogen must not be disregarded, the focus remains on the potassium content.
At the end of the year it is advisable to prepare for the winter. The grasses are susceptible to disease due to nutrient deficiencies. We recommend a balanced autumn or potassium fertilizer against the winter hardiness. The autumn fertilizer is low in nitrogen and is especially intended to strengthen the roots, in order to get through winter optimally.


Long-term fertilizers provide the grasses with a metered lawn nutrition and ensure the storage of nutrients in the soil over a longer period of time. The balanced ratio of nitrogen, potassium, phosphorus and magnesium in lawn fertilizers ensures a constant supply of nutrients to the grasses. The special fertilizer is applied in the spring and ensures a uniform density growth, protects against burns and prevents nitrate leaching. The mechanisms of action of the main nutrients are given for about 6 to 8 months and make the lawn hard-wearing throughout the year.
Worth knowing about lawn fertilizer soon
  • Lawn fertilization is an important basis for beautiful and well-kept lawns. Yellowish or pale grass coloration as well as gaps on lawns indicate a lack of nutrients.
  • Grass, like any other plant, needs special nutrients to grow healthy.Lawn fertilizer is optimally adapted to the needs of turf grasses.
  • Lawn fertilizer contains the basic nutrients nitrogen, phosphorus, potassium, calcium, iron and magnesium.
Fertilize the lawn - the right time
The lawn is fertilized in spring and autumn. Prior to fertilization, the lawn is scarred to remove dead plant matter and weeds. In addition, scarification has a positive effect on soil quality. The first fertilization takes place in spring, when the grasses drive out new green. As a rule, the growing season begins in early March to April.
Lawn Care - Lawn Mowing
Mowing the lawn is an important and indispensable part of lawn care. The regular mowing counteracts the weed formation and ensures a dense growth. The lawn is mowed for the first time in spring. In order not to strain the grass unnecessarily, the first cut should not be shorter than three centimeters. Then the lawn can be cut back to normal.
