My husband built a very large potato box for planting tubers in. We are getting ready to add the dirt and the potato seeds. Few questions:
1. The box is huge, roughly 4' x 4'. We have purchased a bag of 16 potato seeds that I understand need to be cut in half, as there are 3-4 shoots on each potato. Do we plant ALL the potato seeds at once, or do we add new seeds as the plant growth begins to emerge to roughly 12" and we cover with dirt?
2. These seed potatoes have very long sprouts - should I cut them down before planting? Pic included.
