A lifetime farmer, born in 1922 in Germany, Maria Thun received her introduction to Biodynamics at the Institute for Biodynamic Research.
She was fascinated by Dr. Rudolf Steiners indications concerning the effect of planetary rhythms. Maria Thun grew radishes, potatoes and grains for almost three decades, noting the positions of the moon. She took conscientious notes on the production of the different parts of the plants.
Years of exploration led her to conclude, that root crops are enhanced in quality and quantity if sown when the moon is transiting through the earth signs Capricorn, Taurus and Virgo; flowering plants do best when the moon is in the air signs Libra, Aquarius and Gemini; fruits did better when planted while the moon is in the fire signs Aries, Leo and Sagittarius. When the moon is found in the water signs Cancer, Scorpio and Pisces, leafy crops do best.
These observations are based on the observable phenomenon as it appears in the sky (sidereal) from Earth as opposed to heliocentric, tropical data. Her undaunting labor inspired her Biodynamic Sowing and Planting Calendar.
This work led to the development of other calendars, most notably Stella Natura. Maria Thun’s scientific research should be an inspiration to all biodynamic gardeners and farmers.
Maria Thun passed away February 9, 2012
