Calendula is easy to grow from seeds directly sown in the garden or containers. Plant seedlings outdoors after the threat of frost has passed. Calendula will tolerate poor conditions but grows best when it has rich soil.
Once established, it doesn't need much water or fertiliser to grow. Calendula is a full sun plant, however, it's not a fan of sweltering hot temperatures and might start wilting in intense heat. Calendula generally prefers full sun, but it sometimes languishes during the hottest months unless it receives some afternoon shade in hotter areas. Like most members of the daisy family, calendula needs a well-drained soil high in organic material, dense, wet soils can cause the roots to rot. Water frequently until the plants are established. Mature plants thrive on only occasional watering. Avoid too much water with these plants.
