http://www.durgan.org/URL/?PotatoH 27 May 2009 Last hilling of Potatoes.
The four rows of potatoes were hilled. This gives a depth of six to eight inches of soil above the seed potato. In the valley formed after hilling, the space was filled with compost. This was not necessary, but the compost was available and it will supply nutrients.
