Growing Instructions
Calendula prefers the cooler parts of the growing season and can tolerate light frosts easily. It’s an annual (or short-lived perennial in warmer regions). You can direct-sow calendula seeds as soon as the soil can be worked in early spring. Sow seeds about 1/4" deep and cover them completely since they germinate best in darkness. Plant in reasonably fertile, well-draining soil. Seeds will sprout in 1-2 weeks. Space plants about 6"-12" apart. Calendula grows well in full sun to part sun. Keep the soil evenly moist. Don’t let it dry out for long periods, as that can stress the plants. Deadhead the flowers to encourage the plant to keep flowering abundantly. If you neglect deadheading, calendula will slow down flower production since it’s trying to set seed.
