The inflammation in joints causes spasms in the muscles adjacent to the joints, which is probably why people have hand cramps, explained Richard Brasington, MD, a rheumatologist at Barnes-Jewish Hospital and Washington University in St. Louis.
Grow 1 plant to yield 5 to 10 potatoes. Yield 10 to 20 pounds per 10-foot row. Space seed potatoes 10 to 14 inches apart in trenches 24 to 34 inches apart.
Many potatoes mature within 80 to 120 days after planting, depending on cultivar and conditions. For new potatoes (usually about an inch or so--or 2.5 cm--in diameter), a general guideline is to harvest them when the plant is in bloom.
