Besides clay, peat also has very good properties in terms of water storage. Therefore, the more peat is replaced in a soil, the more important a high proportion of clay becomes. The soils from frux therefore contain fresh natural clay. This has already proven itself in professional horticulture for decades.
Fresh natural clay in a potting soil increases its storage capacity for water and nutrients. This compensates for fluctuations during prolonged drought or heavy rain, especially since it prevents nutrients from being washed out by watering or rain. It thus protects plants from nutrient depletion – and, because it contains valuable trace elements, also from deficiency diseases. This promotes lush blooms and the development of aromas in herb, vegetable and fruit plants.
Here’s what you should look for in peat-free soil
Peat-free soil must be loose so that the plant roots are supplied with oxygen and can grow healthily. If wood fibers are present in the soil, this is a positive indication that the soil is sustainable and has a good structure. As mentioned, to increase the storage capacity for water and nutrients, a peat-free soil should contain clay. Unlike clay granules or flour, fresh natural clay – which shows up as a gray color when the soil is spread between thumb and forefinger – is evenly distributed throughout the soil. Thus, it can develop its positive properties as a water reservoir and nutrient buffer not only selectively, but is also not washed out so quickly.
Buy from a gardening retailer
As with all high-quality soils, you should also and above all buy peat-free soil from specialist garden retailers – i.e. garden centers, nurseries and tree nurseries. On the one hand, because such soils incorporate many years of experience from horticultural practice, such as the soils from frux. On the other hand, plants available in specialized stores have already been grown in high-quality soil. When repotting or planting out, they should also be placed back in such soil, otherwise damage can occur that is usually almost impossible to reverse.
Organic does not automatically mean peat-free
Organic soil is not the same as peat-free. Only if it says “without peat” or similar on the soil does it actually contain no peat. The organic fertilizer added to frux organic soils is gradually converted by microorganisms and its nutrients are made available to the plants as needed.
