Carrots are slow to germinate, so plant with a quick germinating / growing crop, such as radishes, to mark your rows. Carrots were first domesticated 5000 years ago in today's Iran and Afghanistan, and at that time they came in black, red, white and purple. Today's orange carrots were created in the Netherlands as a tribute to the ruling House of Orange.
