Business planning is of utmost importance for any company or organization in order to function effectively and achieve desired results. Planning reduces the possibility of mistakes and defines the framework within which the business processes of a company or organization take place. The same applies for the communication plan, an important link in today's fast-paced and changing business market with which one sends the desired message to the target audience through various communication channels and then evaluates the results. If no clearly structured communication plan exists, it will be difficult to achieve desired communication and business results. Correspondingly, the focus of this paper is on the creation of a communication plan for the company Bio Zaštita, which produces natural means for plant breeding. This paper includes an overview of the theoretical framework for the communication plan, communication planning, and strategic and integrated marketing communication. In addition to the theoretical part, semi-structured in-depth interviews were conducted for the purposes of this work with Mislav Fucijaš, owner of the company, Dalibor Milić, owner of the Milić Plant Nursery, and Anita Majstorović, from the agricultural products store Agros Zagreb. Furthermore, the author conducted an analysis of the company’s press releases, communication on social media networks Facebook and Instagram as well as public opinions and attitudes using an online survey method to examine the positioning and communication of company Bio Zaštita in public consciousness. A communication plan has been devised on the basis of research results with the aim of attracting new customers and garden enthusiasts as well as improving the positioning of Bio Zaštita as a leading company in the production of bio stimulants on the Croatian market and beyond.
