Calendula is a frost sensitive annual that prefers full sun and well-drained soil.
Direct sow seeds outdoors once the danger of frost has passed. Optimal soil temperatures for germination are 65-85°F. Sow seeds 1/8" deep and 4-6" apart. Seeds will germinate in 8-14 days. Thin seedlings so mature plants are 12-16" apart. Seeds can also be started indoors and transplanted outside once the danger of frost has passed. Plants will readily self-seed.
Calendula flowers are used medicinally and as food coloring. Harvest flowers when they are fully open. For season long blooms, continually remove spent flowers.
