Carrots reproduce by way of seeds. Unlike potatoes and other root vegetables, they aren't grown from tubers or rhizomes. Carrots are a cool or late season crop that grows best in temperate environments.
If left unharvested, carrots develop tiny white flowers borne in umbels. These attract insects who fertilize the plants. After the plant is fertilized, the umbel curls up into what looks like a bird's nest. The resulting seeds are flat and have five ribs.
Once the carrot seeds are planted, they should germinate in six to 14 days. They need soft, pH neutral soil to develop a long, healthy taproot.
