Growing carrots in a circle rather than rows eliminates the need for a lot of space and will lessen your workload. There is no weeding between rows and the soil is kept moist so carrots grow sweet and succulent. Circular rows of carrots are watered from the center of the circle. A special irrigator sprays water down and around the sloped surface of the Crop Circle to carrots growing at the perimeter. The irrigator is so efficient, that it only takes one cup of water for each row once every second day – 1/10th the water needed if you were growing carrots in a garden using conventional irrigators. Growing carrots in a pot would require about 2 or 3 cups a day depending on the size of your pot. That would be enough water to grow 50 to 100 carrots in a pot. Growing carrots in the garden may need a gallon (16 cups), which would grow 800 carrots or more in a little round garden.
