Starting Calendula from Seed
Calendula can be planted from seed indoors 6-8 weeks prior to the last frost of the season. Light inhibits germination so keep the seeds covered lightly by soil.
Calendula is easily grown from seed sown directly into the soil. Prior to planting, prepare the soil by working three inches of rich compost and one teaspoon of an all purpose fertilizer per square foot, six to eight inches into the soil. Plant the seeds ¼ deep.

Care and Maintenance
Calendula performs well with regular watering. 1 to ½ inches of water per week during the summer will result in optimal growth. Immediately deadheading spent flowers will encourage bushy plants. If flowering dwindles, cut back plants severely.
Calendula deters nematodes and general garden pests making it a great companion plant for tomatoes and potatoes. It is also believed to deter beetles so works well planted among beans and squash.
