Maria Thun – see here for more about her – has been doing practical research with biodynamics and the calendar since the 1950s. She began by carrying out experiments to attempt to establish a connection between the growth of plants and the movements of the stars. Her first experiment was to sow a plot of radishes every day for an entire growing season and observe the performance of each sowing.
She discovered four very noticeable differences in the plots. Some produced larger roots, others larger leaves, others again produced more flowers and the fourth group went more quickly to seed. This was the beginning of her Star Calendar.
She has subsequently done, and continues to do, a massive amount of scientific research into biodynamic growing and updates the calendar each year with her latest findings.
- NB – Maria Thun died in February 2012 but her son continues her work, including the Star Calendar.
