Sow seeds about 1-inch apart. After they begin to develop you are going to thin them out. Cover the seeds Space several rows around 20-inches apart. Expect Coriandrum sativum to germinate about eight to 10 times after soil temperatures reach 55 degrees Fahrenheit.
Water the seeds with around 1/2 inch of water. Keep the soil moist until germination.
