To the MEDIA CENTERStrong roots for a flourishing future
Plants do not live on light and water alone. The use of fertilizer is also essential for strong, lush greenery, lush, long-lasting flowering and increased resistance to pests. For millions of flower and garden enthusiasts, the Mairol brand has become a byword for the best and most balanced plant nutrition. This is because all Mairol products are based on the many years of craftsmanship and scientific experience that has been passed down from generation to generation in the founding Maier family from Heidenheim in Württemberg.
Today, this wealth of experience is combined with the latest findings in plant and garden culture. Added to this is the careful selection of quality basic ingredients, the enrichment with phytohormones and trace elements, as well as a sensitive and balanced mixture of ingredients. The Mairol brand thus stands for a range of top-quality universal and specialty fertilizers.
Birthplace Olgastrasse
It all began in Olgastrasse in Heidenheim. This is where David and Hans Maier acquired the Eberhard drugstore in 1919, continued to run it as “Olga-Drogerie Gebrüder Maier” and began manufacturing and selling the first Mairol products the following year.
The Maier brothers had already had the idea for this during their childhood in Gussenstadt. When the two got access to the relevant raw materials during their druggist apprenticeship, they tinkered around with a so-called “nutrient salt fertilizer” - with success. On 1 May 1914, the fertilizer for plants was registered as a legally protected trademark.
The start of production took some time because the First World War intervened. After that, however, nothing stood in the way of marketing and production soon had to move from Heidenheim to Gussenstadt due to lack of space. Herbert E. Maier, Hans Maier's son, expanded the factory over the decades, developed a range of new specialty fertilizers and established Mairol as a well-known and successful brand throughout Germany and internationally. In the 1970s, Mairol was even the first fertilizer manufacturer to advertise on television.
New Management in 2015
In 2015, Andreas Zettler and Dr. Christian Zettler took over the company from the owner family Ruoff-Maier and saved it from closure due to a lack of succession planning. A well-known traditional brand is successfully led into the future. The production site has since moved from Gussenstadt to Aham in Lower Bavaria. The Mairol brand has already been marketed from there for several years. The mission: New products and innovations in the premium segment.
Today, Mairol is consolidated by its tradition and experience and will remain a manufacturer of high-quality products thanks to state-of-the-art technology and contemporary thinking. One thing will never change: Quality is always Mairol's top priority.
From universal fertilizers to special fertilizers
Mairol products are specially tailored to the needs of plants. Whether it's strong growth, magnificent flowering or the healthy development of demanding rarities - the Mairol range always offers the right product. Because plants need more than just water and air.
