As soon as the first spring-like temperatures are reached and the sun can be seen more often, many hobby gardeners go to hardware stores, garden centers and discounters to get potting soil. After all, the dreary sight of winter should be replaced with colorful flowers and plants as soon as possible.
What actually sounds so uncomplicated is far from easy. As with many other things, there are an infinite number of varieties and suppliers of plant soil. The quality differences are also very large and it is not always possible to determine whether the price is good or bad. It is hardly surprising that laypeople reach their limits here. Last year in April there was a very interesting report on the ZDF program Volle Kanne. Here the garden expert Elmar Mai explains how good soil differs from bad soil and what must be considered when buying. Because it's not always what it says on the tin.Peat is not a good ingredient in potting soil, says Elmar Mai. He therefore advises to use coconut clay (e.g. available here) because it is fibrous and therefore does not dry out so quickly. However, this soil must not be used alone, but should be mixed with other high quality soil.
