Making Biodynamic Preparations with Aaron from Harvest Farms

Today, we had a visit from Aaron from Harvest Farms. He brought us some beautiful red oak bark, casuarina and nettle leaves from his farm. We picked yarrow, chamomile flowers, and dandelion from our gardens, put the flowers to dry, and chopped the red oak bark to a fine crumb. All these ingredients are ready to be dried and stored to make biodynamic preparations.

We packed the nettle leaves into a terracotta pot, buried it in our garden to compost down for the season. The result will be a compost, rich in essential minerals for the soil.

Experimenting with Biodynamics

In the Lyttleton woven garden bed, the yarrow is flowering, and we would like to try to use it in a biodynamic preparation.

The Yarrow (502) preparation is made with yarrow flowers placed in the stags bladder, hung in the sun during the summer and buried in rich soil during the next winter. This preparation stimulates the potassium, silica and selenium activating bacteria in the soil and helps combine sulphur with other substances. It is said to remedy weaknesses in flowering and fruiting and strengthens the plant against insect attack. 

Yarrow is a very useful herb to have in your garden as it has many medicinal uses and its leaves are fantastic for the compost. This is because the plant's leaves accumulate many essential nutrients for building rich, healthy soil.
