Your go-to for fertilizers and plant boosts
since 1996
How HESI came about
The story
A German woman and a Dutch man fell in love with plant care. Siglinde was a scientist, working on various projects in a laboratory. One of her side projects was the development of a high-quality fertilizer. For this passion project, only the finest ingredients were considered, and no expense or effort was spared. The same recipe, with the same quality standards, is still used today. Their friends, who were involved in cultivation, were not achieving the desired results. These cultivators were challenged and desperately needed a high-quality fertilizer. With their passion, experience, and motivation, they embarked on a journey together and founded Hesi Plantenvoeding. They said goodbye to their old lives and never looked back.
"What should we name our company?" Henk asked. After some brainstorming and discussion, they realized it was a passion for both of them, so why not combine their names? Thus, the name "HESI" was born: a combination of the first names of the two company founders.
HE stands for Henk and SI for Siglinde.
High-quality fertilizers
Produced by HESI
Plant and soil additives, blended, filled, and packaged in our own production facilities in Kerkrade, the Netherlands. We've been doing this with love and passion since 1996.
Thorough research into the mysteries of plant metabolism has enabled HESI to develop an optimally balanced composition for every phase of plant life. The result is a range of fertilizers for every developmental stage, but universally applicable, rather than specific fertilizers for each individual plant species. Additional vital substances such as vitamins and amino acids allow the plants to boost their energy levels. This makes growing house, garden, and patio plants a true pleasure.
Hesi is a thriving, internationally operating company with a global reach across Europe, the Americas, Asia, and South America, characterized by a personal touch and a down-to-earth approach. Plant lovers can find the nearest Hesi shop in our Retailers section.
2025
To this day
Hesi has helped more than 1,000 companies and individuals with its solutions. Our secret? Listening carefully and exceeding every customer's expectations with genuine ingredients, in-house production, and personal customer contact. The inspiration for founding the company—the smiles on their friends' faces—is what has driven Henk and Siglinde all these years.
