My procedure is to place the potato in soil just below the surface and let it grow in light. The slips grew well (25 days) and were removed and placed in water for about a week to develop stronger roots. Then they will be planted in a pot to grow, until planted in the outdoor garden. I find the growth is excellent using this method, and it is convenient since only six plants are required.

Apparently one can eat the vegetation as a green, which will be tried if the plants get too large before time to plant out in June. The plants were placed in a window with sunlight available.

They were placed in the greenhouse. Establishing strong roots prior to planting in the outdoor garden improves production.
