Care Instructions
Calendula officinalis is relatively easy to care for. It prefers full sun and moderate temperatures. Water the plant regularly, allowing the soil to dry out partially between waterings. It can tolerate a range of humidity levels but prefers moderate humidity. The plant can be grown both indoors and outdoors.Harvest
Calendula officinalis, commonly known as pot marigold, is typically ready for harvest about 60 days after planting. The flowers should be harvested when they are fully open, usually in the morning after the dew has dried. To harvest, gently pinch or use scissors to cut the flower heads just above the first set of leaves. Regular harvesting encourages more blooms. Ensure the flowers are dried properly if they are to be stored for later use, as moisture can lead to mold and spoilage.Soil
Calendula officinalis prefers well-draining loamy soil. Ensure the soil has good drainage to prevent waterlogging, which can lead to root rot. A slightly acidic to neutral pH is ideal for this plant.Fertilizer
Use a balanced fertilizer with a nutrient composition of 5-10-10. Fertilize the plant every 4-6 weeks during the growing season to promote healthy growth and flowering.Repotting
Repot Calendula officinalis when the plant outgrows its current container or if the soil becomes compacted. Choose a slightly larger pot with good drainage. Repotting is best done in the early spring before the growing season begins.Propagation
Calendula officinalis can be propagated by seeds. Sow the seeds directly in the soil in early spring or start them indoors 6-8 weeks before the last frost. Keep the soil moist until the seeds germinate.Pruning
Pruning is beneficial for Calendula officinalis to encourage bushier growth and more flowers. Deadhead spent flowers regularly to promote continuous blooming. Prune back any leggy or overgrown stems.Toxicity
Calendula officinalis is generally non-toxic to pets and humans. However, some individuals may experience skin irritation or allergic reactions when handling the plant. It is always best to handle with care.REVOLUTIONIZE YOUR PLANT CARE
