WHEN TO PLANT CALENDULA SEEDS

Calendula can be sown directly outdoors, after the threat of frost. They can also be started indoors in trays, 3-4 weeks before your final frost date.

WHERE TO PLANT CALENDULA SEEDS

Calendula does well in Full Sun and is tolerant of partial shade. Keep in mind that Calendula can struggle in hot summer heat, so would benefit from afternoon shade.

HOW TO PLANT CALENDULA SEEDS

Plant Calendula seeds in rows, pressing 1/2 inch deep, and allowing 5 inches of space - this covering is important as sunlight can disrupt germination. Seeds should germinate within a week.

HOW TO CARE FOR CALENDULA

Pinch off spent blooms to encourage new growth. A layer of mulch in the Spring around the base of the emerged plants may help discourage weeds and keep your soil moist.
