|potato flower means it is soon time to harvest|
Potatoes are easy to grow and can be stored for a very long time.They prefer a slightly acidic soil with a pH factor of about 6. They should be planted in early spring, and the soil should be at least 45 degrees F. They should not be grown in the same soil year after year. I grow them in pots and my soil is always new, so crop rotation is not an issue here.
One week before planting, I set my seed potato on the dry warm balcony with full light to induce sprouting. Then I chopped up the sprouts, with the eyes or ´buds´ fully intact. The seed formed a thick callous over the cut which helped prevent it from rotting once planted. This is an important step that should not be over looked.
The best way to get more potatoes is to keep covering the plant with soil. Do not bury the plant entirely with soil. Leave just enough for the plant to push through. Some people do this with tires, others build potato boxes.
