Should I let potato plants flower?

You should allow your potatoes to flower. By harvesting after they flower, you allow the potato plant to grow to its potential. However, not all potatoes will flower or produce fruit. Whether your potatoes flower or not, the best time to harvest them is after above-ground greenery starts to turn yellow and die.

What does it mean when potato plants flower?

Flowering just means that the vines are mature enough and have enough leaf area to start forming tubers. It doesn't mean the tubers are ready to harvest. Until they reach mature size, your potatoes should be watered regularly though the summer, from 1 to 3 inches of water per week, as needed.
