Our 5 x 5 m experimental garden permitted 38 such mounds, each approximately 40 cm in diameter and 30 cm high.
In the first season at Robin Hood Bay, we grew two plants on
each of these mounds, one on the north side, and one on the south.
We found that 19.kg of tubers was produced from plants on the northern side
and only 9.8 kg on the south. Whether this is due to increased solar
energy or differences in soil temperature on each side of the
mound required a separate project,
carried in the second year.
During the harvest, all tubers from each plant were bagged
separately.
