| I am trying to determine when potato plants are ready for harvest.the plants are about 6 to 9 inches tall. thank you |
| Your potato plants will flower later this summer. After they flower you'll know that spuds are beginning to develop underground. When the tops of the plants die down competely, the potatoes will be ready to harvest. (But you can cheat a little and harvest new potatoes after the flowers die off). Enjoy! |
