What happens in the bee colony in individual seasons? What needs to be done in the apiary? Bee expert Wolfgang Ritter answers these questions with the help of a phenological calendar, which includes a total of 10 seasons and is guided by certain developmental stages in nature, for example the flowering of certain plants. The book is thus applicable in every area - even in times of climate change! Due to the neutral presentation of operating methods and type of hives, this guide is suitable for every beekeeper. Beginners and advanced beekeepers will find here a very good working tool, which, thanks to its clear structure, helps in all beekeeping activities.
