Potato Test Box
http://www.durgan.org/URL/?EIFPD 17 August 2009 Potato Test Box
The seed potato is about six inches below the bottom of the box. The plant was carefully hilled often as the stalk grew. Hilling ceased when the flowers started to form. According to some there should be potatoes along stolens growing all along the stem. Experience has indicated that this is simply not the case. It will be a few weeks before the upper boards are removed and pictures supplied at each removal.
