Rosemary comes from the evergreen maquis of the Mediterranean region and has adapted perfectly to the prevailing conditions over the millennia. This not only applies to the climate, but also to the ideal soil conditions.
As sandy and permeable as possible
In accordance with its origin, the popular kitchen herb prefers lean - if possible sandy - well-drained and dry soil. The plant develops very widely branched and deep-reaching roots, which are able to draw moisture and nutrients from the soil even from a depth of several meters. So that the roots can penetrate the soil well, the soil should be loose and permeable. Rosemary does not like heavy, loamy soil - not only because it cannot grow naturally there, but also because such soil is very good at storing water. However, the plant, which is very sensitive in this respect, does not tolerate high levels of moisture or even waterlogging.
tips and tricks
Like almost all Mediterranean herbs, rosemary loves soils with a pH in the neutral to alkaline range - limescale is not a problem at all for the sun-worshipper. You can therefore water the plant with tap water or fertilize it with lime once or twice a year without worrying.
