Propagation of coriander is via seeds. Soaking seeds in water before planting will promote germination. If grown in a tropical and hot climate plant in a partly shaded area. If the plants are not provided with a sufficient amount of water they can quickly bolt to seed.

The best time for seed germination is when the temperature has been consistently warm (20⁰C) for a fortnight. If growing for its leaves put it in light shade. If you’re wanting the seeds, both sun and little water will make it seed. Coriander does not like extreme heat, if it experiences this, it will bolt to seed. Coriander in the garden attracts pollinators such as bees.

It is said that coriander will create a larger crop of seeds if grown with anise. It is advisable not to grow near fennel as the fennel will be unlikely to germinate or seed.
