When to Plant Calendula Seeds
Calendula can be sown directly outdoors after the threat of frost has passed. Alternatively, you can start them indoors in trays 3-4 weeks before your final frost date.
Where to Plant Calendula Seeds
Calendula thrives in full sun and is tolerant of partial shade. However, it can struggle in hot summer heat, so providing afternoon shade can be beneficial.
How to Plant Calendula Seeds
Plant Calendula seeds in rows, pressing them 1/2 inch deep into the soil and allowing 5 inches of space between each seed. This covering is important as sunlight can disrupt germination. Seeds should germinate within a week.
How to Care for Calendula
Pinch off spent blooms of Calendula to encourage new growth. Additionally, adding a layer of mulch around the base of emerged plants in the spring may help discourage weeds and keep the soil moist.
