From its beginnings, Wallula vineyard was planted as a Biodynamic vineyard on virgin land without disturbing the native vegetation. Dan Nickolaus, the vineyard manager at Wallula, uses no pesticides and no herbicides and he is working to make this vineyard self sustainable. Dan uses all the Biodynamic preparations with an emphasis on horn manure, silica, stinging nettle and horsetail teas. Dan also makes his own compost and has a herd of sheep to control the weeds in the vineyard.
