Calendula officinalis is a cool-season plant that prefers mild temperatures between 50-75°F (10-23°C). It can tolerate light frost and may even continue to bloom during the winter in milder climates.
Calendula officinalis prefers well-draining soil that is rich in organic matter. It can tolerate a range of soil pH levels, but a slightly acidic to neutral soil with a pH of 6.0-7.0 is optimal.
Calendula officinalis prefers full sun to partial shade, but it can also grow in shaded areas.
Calendula officinalis requires regular watering to keep the soil moist, but it can tolerate some drought. Overwatering can lead to root rot, so it's important to ensure the soil is well-drained.
Calendula officinalis doesn't require much fertilizer, but a balanced, all-purpose fertilizer can be applied once a month during the growing season to promote healthy growth and blooming.
Calendula officinalis can be propagated from seeds or cuttings. Seeds should be planted in the fall or early spring, and cuttings can be taken in the spring or summer.
