Potting soil and potting soil are offered in specialist garden shops, but also at discounters. The products are usually sufficiently provided with a nutrient depot and are of acceptable quality. To get the most out of both soils, you need to know what's inside.

Potting soil is used for both young plants and larger vegetable plants

The potting soil

Potting soil contains valuable ingredients and is suitable for potted plants in the room, on the balcony and terrace. In addition to peat contains potting soil

  • lime
  • compost
  • wood or coconut fibers
  • NPK fertilizer (nitrogen N, phosphate P and potassium K

is also possible

  • Perlite (37.51€) (volcanic glass) for water storage
  • Clay granules for water storage

The potting soil

This is a humus-rich substrate that is industrially produced. It is generally used for the garden, but also for greenhouses, raised beds and container plantings.
Young plants and mature plants are cultivated in it. Therefore, the composition of the potting soil must offer enough nutrients, for example:

  • Humus, usually bark humus
  • compost
  • coconut fiber or
  • wood fibers
  • algae
  • Guano (121.99€) as fertilizer
  • peat
  • long-term fertilizer

Differences between potting soil and potting soil

For the most part, the composition of the two earths is identical. However, there are small differences that become relevant depending on the cultivated plant.

fertilizer

The potting soil has less nitrogen, phosphate and sulfur, but more potassium. The potting soil contains less potassium, but more nitrogen, phosphate and sulfur. The proportion of magnesium is the same in both soils.

volume

This is only contained in the potting soil in the form of granules. This ensures optimal water storage. This is especially important for potted plants.

The pH

The potting soil has a pH of 6.1, while the potting soil is between 6.4 and 6.5

More properties

The potting soil must be structurally stable as it must provide the potted plants with support. Microorganisms that the potted plants need to thrive can develop well in it. Potting soil stores water and oxygen.
The potting soil loosens the garden soil, it benefits from the natural structure of the garden soil.

Potting soil or potting soil for growing vegetables?

Both soils are of high quality and allow the flower or vegetable plants cultivated in them to thrive. Due to the differences, potting soil can be improved individually if the exact nutrient requirements of a plant are known.
