How to fertilize the lawn with compost

Nutrients for grasses and soil organisms

Regular mowing of the lawn constantly removes nutrients from the soil. The grasses have to repeatedly draw nutrients from the substrate so that they can grow back. You need phosphorus, nitrogen, magnesium, potassium, and calcium. Trace elements such as copper and manganese as well as iron and boron are essential for healthy plant growth. A well-decomposed compost substrate can provide the nutrients. It provides an organic fertilizer and at the same time improves soil quality.

Many soil organisms feed on the plant components in the compost. Their activity ensures that nutrients are made available to the plants. They loosen the soil and ensure optimal ventilation. Soil organisms have an influence on the water retention capacity in the substrate. In sum, they are used for lawn care and should be supported by lawn fertilization.

Time for fertilization

Fertilize the lawn in March or April to support the vitality of the grass. Compost increases the resilience of the lawn and ensures that it shines in a lush green. The compost soil is ideal for intermediate fertilization during the summer months. If you fertilize the lawn with compost in October, you ensure a supply of potassium and phosphorus. During this time, the plants use the nutrients for root growth and the development of runners.

Tips on correct fertilization

Sprinkle the compost on the lawn in a thin layer. Work the substrate carefully into the grass mat so that the nutrients get better into the soil. Make sure that the lawn is watered thoroughly. This ensures that the compost mixes with the soil. The soil organisms absorb the compost so that after two days you can no longer see anything.

What makes a good compost fertilizer:

  • no rotten plant parts
  • fine crumb structure
  • sufficient moisture

Use only well-decomposed compost substrate for lawn fertilization. A filled ten liter bucket is enough for an area of ​​ten square meters. You can reduce the amount by fertilizing your lawn several times a year.
