The Kocaeli Metropolitan Municipality has planted approximately 2.5 million medicinal and aromatic plant seedlings, primarily rosemary, across 1200 decares of land as part of the Medicinal and Aromatic Plants Project. This initiative aims to support rosemary, medicinal mint, and lemon balm growers and has also created job opportunities for women. Soil analysis and consultancy services have been provided to farmers by agricultural engineers. In Derince district, 120 thousand rosemary seedlings have been planted on a 59 decare field, with a five-year contract in place for harvest and purchase by the municipality.
