What Are "Seed Potatoes"?
Potato "seed" is whole or cut up potatoes that have been grown especially for growing crops of potatoes and are usually certified virus-free. Home garden potatoes are not commonly grown from seeds like tomatoes or lettuce. Supermarket potatoes do not make good garden seed as they are usually treated with sprout inhibitors and will produce small yields and inferior quality tubers.
How Many Pounds Of Seed potatoes Do I Need?
On average, one pound of seed potatoes will plant 10 feet of garden row and yield 10 pounds of potato crop. This varies with varieties and growing conditions in your own garden, and yields can be much higher or lower. In general, "fingerling" varieties like Russian Banana yield much higher crops than "conventional" varieties like Russet Burbank.
When Should I Plant Potatoes?
Plant seed potatoes 2 weeks before the average last frost in your area, or anytime the soil temperature is above 55 degrees Fahrenheit.
When Do I Harvest Potatoes?
Baby, or "new" potatoes can be ready to harvest as early as two weeks after plants have flowered. The ideal time to harvest mature tubers is after the vines have died down or been killed by frost. Alternatively, the vines can be broken or cut off near the end of the season. Leave the tubers in the ground for a week or two after the vines have died to allow the skin to "set" before harvesting and handling.
