The calendula flower or flowering herb is an annual which will readily reseed. Too much calendula care can result in stunted or slow growth.
Light - Calendula generally prefers full sun, but it sometimes languishes during the hottest months unless it receives some afternoon shade.
Soil - Like most daisy family members, calendula needs a well-drained soil high in organic material.
Water-Water frequently until the plants are established. Mature plants thrive on only occasional watering. Avoid too much water with these plants. Like most herbs, calendulas are adaptable and do not require a lot of maintenance. Roots will often adapt to the space provided. As the calendula prefers cool temperatures, flowers last longer in filtered sun or shady areas.
