Our recommendations

At the Magnesium sulfate from bleu & marine Bretania everything is just right: The proportions of water-soluble magnesium oxide and sulfur are comparatively high. As a result, the Epsom salt has an excellent effect - yellowish-brownish discoloration disappears - giving way to a rich green. Furthermore, you can get by with the 3.5 kilograms for a long time, but you don't have to store an excessively heavy and bulky pack. In addition, almost all of the extremely enthusiastic reviewers at Amazon praise the very simple application. The Epsom salt can be sprinkled and then worked into the ground or easily mixed with the irrigation water. The manufacturer conveniently gives detailed information on how much magnesium sulfate is useful per application. A really good product with a convincing price-performance ratio.

The Epsom salt from Grüner Jan deserves second place - for two reasons: the high quality and the very affordable price per kilo. Compared to our test winner based on the basic features and reviews on Amazon, the proportion of sulfur is significantly lower. Nevertheless, the magnesium sulfate achieves the desired effect, if the descriptions of most of the customers are to be believed.

Dehner's Epsom salt has practically the same properties as the magnesium sulfate from Grüner Jan. In terms of quality, the two products don't seem to take much from each other either. Most of the Amazon reviewers say they are satisfied with the magnesium sulfate. However, isolated critics define the salt as difficult to sprinkle.
